Version 4.12.3

• Release date: September 25th, 2019

• New TouchGFX Core Features (since 4.12.0):

  • Binary Fonts: Binary fonts can be used as an alternative to compiling and linking font information in to your application. The main advantages of this approach is to get a smaller application binary and get a flexibility in providing different sets of fonts with your device.
  • Font Caching: Support for caching binary fonts, suitable for loading only the required characters from a file system, when a string is displayed.
  • Binary Translations: Support for binary translations, suitable for loading translations from a file system as opposed to linking them into the application. Read more about these feature here: https://support.touchgfx.com/docs/development/ui-development/touchgfx-engine-features/using-binary-translations/
  • Support for non-memory-mapped flash storage for 16bpp displays, allows storage of images and fonts in e.g. inexpensive SPI flashes.

• Bugfixes in TouchGFX Core:

  • TextureMapper (bilinear) would fail to draw L8_RGB888 and RGB888 bitmaps on 24bpp displays correctly.
  • Setting a text with a wildcard in a TextArea without wildcard support in combination with RTL could cause a crash.
  • If a CacheableContainer was smaller than the associated bitmap, the size of the container would not be correct.
  • Fixed SnapshotWidget on 8bpp LCDs.
  • Fixed rendering of some Arabic ligatures.
  • Fixed rendering of some Hindi ligatures.
  • Fixed bug when applying certain GSUB substitution rules.
  • Fixed bug that binary fonts contained extra rules.

Version 4.12.0

• Release date: 06-07-2019

• Important upgrade information:

  • Public version of drawGlyph has been removed. Use drawString instead.
  • Using bitmap format ARGB8888 for opaque images will no longer dither to 565 but keep full 888 colors. Using ARGB8888 for non-opaque images will still dither to 565 when the opaque format is RGB565.
  • Images converted to BW_RLE will no longer fall back to BW if the BW_RLE format causes the converted image to be larger. Instead a warning will be generated by the image converter. Use the Designer (or the new configuration file) to specify BW or BW_RLE for each individual image.

• New TouchGFX Designer Features:

  • A custom container can now be nested within another custom container. This enables composing custom components into larger custom components indefinitely.
  • A custom container supports defining custom triggers and custom actions, a screen supports defining custom actions. These triggers and actions support the flow of information from one component to another component. Using such triggers and actions in interactions within the Designer enables doing more real world application behaviour without leaving the Designer. Check out the documentation for further introduction.
  • A Container can now be generated as a CacheableContainer.

• Release date: March 10th, 2017

• Performance

  • LCD4bpp now draws characters up to 15% faster.
  • Canvas widgets now render slightly faster in certain situations.

• New Features:

  • TouchGFX Designer released. The core framework, Designer and environment shell are now bundled in a single installation.
  • Support for Farsi and Arabic ligatures where squences of up to three character are recognized.
  • Added support for Microsoft Visual Studio 2017.
  • TextArea and TextAreaWithWildcard(s) now support setWideTextAction() to automatically break lines and insert ellipsis at end of line, when the line is too long.
  • Added getter functions to Slider.
  • MoveAnimator and FadeAnimator can now clear the callback set for animation ended.
  • Errors from ImageConvert, TextConvert and FontConvert are now shown in the Error List window of Visual Studio.
  • Simulator applications are now Windows programs instead of Console programs.

• Bugfixes

  • AbstractShape::updateAbstractShapeCache() is now a public function and should be called after one or more calls to AbstractShape::setCorner(), to ensure shape is correct.
  • Simulator window can no longer be unintentionally resized.
  • F2 to highlight invalidated areas now works with old HALSDL.
  • PainterGRAY2Bitmap, PainterGRAY4Bitmap, PainterRGB565Bitmap and PainterRGB888Bitmap all failed to validate that painting was inside the size of the bitmap in some situations.
  • HALSDL2 (simulator) now uses 24bpp on screen to make colors in screenshots correct.
  • TiledImage::setOffset() now handles an empty bitmap correctly.
  • TiledImage::getSolidRect() would sometimes report wrong rect.
  • If text in a TextArea was rotated, resizeToCurrentText() and resizeHeightToCurrentText() would swap the width/height.
  • Function getTextHeight() would not take line spacing into account. Functions like resizeToCurrentText() and others that use the getTextHeight() function would not resize correctly.
  • SlideMenu::setState() did not handle EXPANDED state correctly.

• Update Procedure

  • Due to the addition of TouchGFX Designer, installation is now done via an .msi installer.
  • Compatible with existing 4.x applications and HAL ports.

Version 4.7.0

• Release date: December 14th, 2016

• New Features:

  • Source code for all the standard widgets and containers is now included. See the touchgfx/framework/source/touchgfx directory. Note that these classes are still present in the core library, and the source code files are not added to the IAR/Keil/gcc projects per default.
  • Optimized the handling of single frame buffer configuration on TFT controller based platforms, which in many cases eliminate the need for external RAM.
  • Substantial performance optimizations of the canvas widget system and all the standard painters. Expect a very significant increase in performance if many pixels are being drawn, and a smaller increase in performance for minor shapes (e.g. graph lines). The "PainterVerticalAlpha" used in our demos have also been updated.
  • The text converter tool will now combine identical translations across all languages, resulting in reduced footprint. The result of this process will be printed during asset generation. NOTE: This behavior is enabled by default. If you have an existing project where you manipulate the text data structures (e.g. load a single language into RAM), this optimization might break your code. The optimization can be disabled by adding the following remap_identical_texts := no (for "make"-based generation) <RemapIdenticalTexts>no</RemapIdenticalTexts> (for MSVS)
  • Updated SDL version used by simulator from 1.2 to 2.0.4. SDL1.2 is still present in the distribution, but all examples and projects now use SDL2.
  • Support for skinning the simulator with .png files. If the .png files contain non-opaque areas, the simulator window will be shaped accordingly. See display_orientation_example for a code example.
  • On ST targets with Chrom-ART, the Box widget will now be drawn by DMA even when alpha < 255 (BLIT_OP_FILL_WITH_ALPHA support).
  • TextArea and TextArea with wildcard(s) now support setWideTextAction() to automatically wrap long lines.
  • Added the ability to display a "fallback" character in case a non-existing glyph is encountered at runtime. This is configured in the typography sheet of the text database.
  • Added options for forcing the inclusion of additional glyphs in a font. This makes it much easier to handle dynamic texts where the glyphs are not known at compile time. This is configured in the typography sheet of the text database.
  • Output from the TextConvert utility is now post-processed to give significant saving by mapping identical strings to the same memory areas.
  • Added built-in BitmapId called BITMAP_ANIMATION_STORAGE which can be used to refer to the animation storage when assigning a Bitmap to a widget.
  • Added dither algorithm selection from config/gcc/app.mk and config/msvs/Application.props.
  • It is possible to save a simulator screenshot programatically, by using: #ifdef SIMULATOR (static_cast<HALSDL2*>(HAL::getInstance()))->saveScreenshot(); #endif
  • ScrollableContainer now properly ignores invisible elements.
  • DigitalClock now supports a zero to be displayed in front of the hour indicator (if hour < 10).
  • The simulator can now highlight the areas being invalidated. Press F2 to toggle this feature.
  • Added Unicode::vsnprintf functions that take va_list arguments instead of ellipsis.

• Bugfixes

  • Unicode::sprintfFloat did not print <space> instead of '+' if the format string was "% f". Also, the sign of floating point numbers in range ]-1..0[ would not be printed with sign so for example -0.5 would print as 0.5.
  • Fixed a bug that could cause TextureMapper to read outside source bitmap memory area.
  • GPIO.cpp for STM32F769-Discovery and Eval boards had some incorrect GPIO pin manipulations (used for performance measurement).
  • Some methods in Slider.hpp were missing a virtual declaration.
  • Fixed a bug in BoardConfiguration for STM32F769-Discovery board causing 24bpp color mode to be displayed incorrectly.
  • AnimatedImage - setBitmap(..) should not be used and is now private For AnimatedImage use setBitmaps(..) instead.
  • Project files and Makefile have been updated to allow the TouchGFX framework to be placed on another disk drive than the project being developed.

• TouchGFX Environment (version 2.8)

  • "make.exe" is now version 4.1 which allows for parallel compilation, by adding e.g. "-j8" to your make command. This substantially speeds up compilation. If your makefile is from TouchGFX 4.2.0 or earlier, you will need to either update it, or to use make-3.81.exe
  • g++ could in some cases report "There is no disk in the drive. Please insert a disk into drive E:.". This has been fixed by upgrading gcc from version 4.8.1 to version 4.9.3.

Version 4.6.1

• Release date: September 12th, 2016

• Performance

  • Optimization improvements of core library for GCC on Cortex-M4 and Cortex-M7, providing significant speeedup of especially TextureMapper and Canvas widgets compared to TouchGFX 4.6.0.

• New Features

  • New function in HALSDL to set title of simulator window see HALSDL::setWindowTitle().
  • BW_RLE format (1bpp displays) now compresses better. Remember to remove old generated files and re-generate assets.
  • STM32F756G-EVAL using IAR now supports flashing of external memory.

• Bugfixes

  • Added IAR linker redirect commands to fix linker errors when compiling a Cortex-M4 based target with IAR 7.x.
  • Assigning different memory buffers to CanvasWidgetRenderer using setupBuffer() could in rare cases result in memory corruption.
  • TextureMapper could in rare cases draw outside the framebuffer.
  • Setting the offset of a TiledImage did not work properly.
  • Fixed two issues that would in some cases cause memory corruption when deleting dynamic bitmaps.
  • Missing virtual method declarations in AnalogClock added.
  • Fixed a problem in GCC linker script for LPC4088DisplayModule which caused texts and fonts to be placed in external flash.
  • For those using fontconvert.out on its own, the output directory is now automatically created if it does not exist.
  • ScrollableContainers could in rare cases send a wrong drag event to a child.
  • Monochrome (1bpp) displays with width not divisible by 8 would not display text correctly.
  • Slightly increased default touch sample rate on STM32F746G Discovery board.

Version 4.6.0

• Release date: June 14th, 2016

• New features

  • Added support for 2bpp grayscale displays.
  • Added support for 4bpp grayscale displays.
  • New widget TiledImage. Will display one or more repetions of an image. The number of repetitions depends on the size of the widget and the size of the image.
  • New widget RepeatButton. A button that will repeatedly fire click events when pressed.
  • New widget AnimationTextureMapper. TextureMapper with build in animation features. See animation_texture_mapper_example.
  • New containers AnalogClock and DigitalClock, see clock_example.
  • New containers ProgressIndicators, see progress_indicator_example.
  • New container ModalWindow. Creates a window on top of the main screen and a shade on the rest of the main screen. No clicks are passed on to the main screen as long as the modal window is visible. See example modal_window_example.
  • New container SlideMenu. Animating side/top/bottom-menu that has an activate button for sliding it in/out of the screen. A timeout can be set for automitical hiding when idle for a period of time.
  • Canvas Widget Line supports ROUND_CAP_ENDING and setCapPrecision() to control the round cap.
  • Simulator can now generate ticks very close to the frequency of the hardware.
  • Mouse X and Y coordinates are put in the title of the window in the simulator. (press F1 to (de)active this when running the simulator).
  • ST Cube drivers updated to version 1.4.0 for STM32F7 MCU and STM32F7 based boards.
  • Added support for the STM32769I-EVAL board.
  • Added support for the STM32F769I-Discovery board.
  • Screenshots made from the simulator (F3) are now saved under a name with timestamp to prevent old screenshots to be overwritten by accident.
  • Simulator now outputs canvas widget memory usage to easily find optimal canvas memory buffer size.

• Bugfixes

  • DMA drivers for ST boards: express DMA2D instance initialization for STM32F7. Fixed incorrect used of CLUT_CM for F4-Discovery.
  • DMA drivers for LPC17xx, LPC18xx, LPC43xx did not behave correctly if other DMA channels are in use simulatenously. They now properly look at flags for channel 0 only.
  • Touch controller drivers for ST boards now properly checks that initialization was OK before querying.
  • Mouse clicks in the simulator would not always be detected.
  • ImageConvert.exe has RGB565 as default (and sensible defaults for other opque formats)
  • ImageConvert would not work for a BW image scheduled for compression (BW_RLE) and rotation (.90. in filename) if the image would become too large if compressed (falling back to BW format).
  • All Makefiles now use abspath instead of realpath.
  • AnimatedImage now allows the animation to be restarted from the AnimationEnded callback function.
  • QSPI flash size corrected to 64MBytes for STM32756G-EVAL board.
  • Added D-cache invalidation to STM32F7HAL::flushFrameBuffer. This fixes occasional graphics errors on STM32F7 when in single frame buffer mode and fb was located in SRAM.
  • The otm8009a displays (STM32769-DISCO, STM32769-EVAL, STM32469-DISCO, STM32469-EVAL) are now using maximum display brightness.
  • Added a workaround for a bug in IAR 7.50.x regarding va_list name mangling.

• Update Procedure

  • Compatible with existing 4.x applications and HAL ports.

Version 4.5.1

• Release date: March 14th, 2016

• Bugfixes

  • Fixed two IAR linker issues related to resolving the va_list symbol, which would cause some versions of IAR being unable to link the example projects.
  • STM32F4-Discovery board would draw solid rectangles with the wrong color in 16bpp mode.
  • The Canvas Widget Renderer no longer performs unaligned memory accesses.
  • vApplicationIdleHook (FreeRTOS specific) no longer blocks, which previously prevented FreeRTOS from freeing memory if tasks were deleted.
  • Arabic words with accent in the middle would not render properly.
  • Added PixelDataWidget::getAlpha().
  • Unicode::strncpy() with a char* as source would not copy characters with ascii codes above 127 properly.

Version 4.5.0

• Release date: February 2nd, 2016

• New features

  • Support for two new languages, Arabic and Hebrew, with right-to-left text rendering. RTL strings can be mixed with LTR texts and numbers.
  • Support for 24 bits per pixel framebuffers. Images look more detailed, but also consume more memory.
  • Bitmaps can now be created at runtime using method Bitmap::dynamicBitmapCreate. Useful for e.g. displaying .bmp files loaded from an SD card. See dynamic_bitmap_example.
  • Frame rate compensation feature which provides smoother animations if frame rate occasionally drops. Not enabled by default.
  • Bitmap caching is enhanced to allow removal of bitmaps from the cache to make room for caching of other bitmaps.
  • A new widget, PixelDataWidget, is introduced. This widget makes it possible to display raw pixel data obtained at runtime (e.g. video samples).
  • The simulator executable on windows now features an icon for easier identification in the task bar.
  • ST boards supported by TouchGFX can now have just their internal flash programmed from the command using 'make intflash' provided that ST-Link Utility Release 3.7+ is installed.
  • Unicode::snprintf() has been improved and updated substantially to support more of the standard format specifiers like %02d.
  • Unicode::snprintfFloat() added to support floats (in separate function because the "%f" va_args approach would force inclusion of doubles).
  • Quality of image converter dithering has been improved (floating point arithmetics). Also added support for new types of dither algorithms, and can take into account hardware with various wiring of the low (unused) bits in 16/18 bit displays.
  • touchgfx::ButtonWithLabel now contains a method, updateTextPosition(), that can be used to ensure horizontal text centering when changing label content (e.g. when changing language).
  • touchgfx::TextArea has a new method, setBaselineY(), that allows placing texts according to a text baseline instead of upper left corner.
  • The internal format of glyph encoding now stores the first pixel in the least significant bit instead of the most significant bit.
  • Specification of color values has been switched from uint16_t to colortype to support seamless switching between 16 and 24 bit colors.
  • The touchgfx::TextArea class now has a method, setIndentation(), that can prevent the glyph of characters from being cut off in the rare case where it extends under the previous character (similarly for touchgfx::Keyboard class which has a new setTextIndentation() method).
  • STM32F7xx and STM32F4x9 ports now support DMA transfers of touchgfx::Box.
  • The GPIO::VSYNC_FREQ signal was previously "toggled" exclusively on "VSYNC" interrupt (NXP LPC18xx, NXP LPC43xx, Freescale MK70F12, ST stm32f4x9). The signal is now high on "VSYNC" interrupt and low on "Front-Porch-Entered" interrupt.
  • GCC support for Cortex-M3.

• Bugfixes

  • Fixed rare crash on STM32F7 caused by speculative caching of invalid QSPI memory region. Update your BoardConfiguration if yours is based on 4.4.x.
  • Fixed occasional display flickering on STM32F746G-DISCO board caused by cache access on FMC bank 1.
  • Handling of the character "%"" in touchgfx::TextAreaWithWildcards has been improved to prevent inserting %% in some special cases.
  • touchgfx::DragEvent and touchgfx::GestureEvent now use and report signed coordinates instead of unsigned. This makes more sense as drags/gestures are expressed in coordinates relative to the drawable receiving them.
  • snprintf("%x") would generate uppper case hex. Now "%X" generates uppercase hex and "%x" generates lower case hex, just like the standard snprintf().
  • Fixed randomness for demos when running on Linux.
  • Fixed redrawing when using heavily italicized fonts.
  • Pointer to ModelListener in Model class for all TouchGFX applications was not properly initialized (NULL).
  • Fixed support for heavily italicized fonts in touchgfx::TextArea.
  • Subtle error in the Image Converter where column 0 could get slightly incorrect pixel colors. As a result the entire image could be slightly wrong, probably not noticeable.
  • Minor error in Slider where values were not distributed evenly.

• Deprecated

  • LCD::drawGlyph() has been deprecated. Use LCD::drawString instead.

• Update Procedure

  • Compatible with existing 4.x applications and HAL ports.

Version 4.4.2

• Release date: November 26th, 2015

• Bugfixes:

  • Corrected rare GUI task hangup on STM32F7 targets when compiling with IAR 7.x

Version 4.4.1

• Release date: October 27th, 2015

• Bugfixes:

  • Corrected occasional GUI task hangup on STM32F7 targets when compiling with Keil 5.x
  • Fixed occasional tearing on STM32 F469 EVAL/Discovery boards when using DSI in landscape orientation and single framebuffer mode.
  • Modified IAR flash loader settings for STM32 F469 boards to enable programming of internal flash (Note: QuadSPI flash must still be programmed from ST-Link Utility as there are no IAR loaders for this)
  • GPIO class for perf. measurement for STM32F746G-EVAL boards now properly uses the BSP_LED functions. Note that only two signals are active on this board per default because LED2 and LED4 use IO Expander, making them unsuited for measuring performance.
  • Removed annoying "Get Alternative File" dialog popups in IAR Workbench when debugging Cortex-M7 applications.

Version 4.4.0

• Release date: October 6th, 2015

• New features

  • Added support for the Cortex-M7 core.
  • Introduced concept of "finger size" for touch input. When used, TouchGFX will attempt to find touchable widgets in the area surrounding the reported x,y coordinates, so users no longer have to click precisely on a widget. This feature makes it substantially easier to hit small buttons. See HAL::setFingerSize().
  • Supports Visual Studio 2015
  • Visual Studio projects for Demos and Examples now include Application.props under Resources for quick access. As always a rebuild might be required when altering the contents of Application.props.
  • Support for Bitmap Fonts in BDF format. If the requested font size is not available in the font file, the font converter will write the supported font size(s) in the error message. See the example monochrome_example for usage.
  • Generating assets now issues better error messages when spaces are detected in paths and file names.
  • All ST boards can now be flashed from the command line provided that ST-Link Utility Release 3.7 has been installed. Simply use 'make -f target/ST/<board>/Makefile flash' to build and flash your application to the connected board. If timeouts occur during flashing, go to Device Manager in Windows and disable "MBED microcontroller USB Device" under "Disk drives".
  • New touchgfx-env version 2.5 available with new gcc cross compiler version 4.9.3. The older version 4.8.4 could generate invalid code for Cortex-M7 cores in rare cases.

• Board support

  • Added support for the STM32F7xx processors
  • Added support for the STM32F746G-DISCO and STM32756G-EVAL boards
  • Added support for the STM32F469 processor with DSI displays
  • Added support for the STM32469I-EVAL and STM32469I-Discovery boards

• Bugfixes

  • TextureMapper and ScaleableImage now draws images correctly when using "rotate90".
  • Fixed potential initialization order bug in STM32F4DMA.cpp
  • Fixed bug that limited number of glyphs in a single font to 32768. Now supports 65536 glyphs per font as intended.
  • Fixed bug that caused hal.lockDMAToFrontPorch(false) to not have any effect in single framebuffer mode.
  • ButtonWithLabel correctly center texts vertically if text contains newlines

Version 4.3.0

• Release date: June 8th, 2015

• New features

  • TextureMapper widget added. The TextureMapper is a highly optimized image renderer that can be used for displaying an image that is scaled and/or rotated in two or three dimensions during run time. This can be used for doing advanced rotation animations of images. See manual or texture_mapper_example for more information. LCD has new methods for drawing triangles and corresponding scan lines, drawTextureMapTriangle and drawTextureMapScanLine
  • Alpha Channel Dithering Images with alpha channel can now get the alpha channel dithered for smoother alpha gradients, see examples or Application Development section in manual for details
  • Compression of 1BPP (monochrome) bitmaps Added image format option of BW_RLE, which will cause bitmaps to be automatically run-length encoded if that takes up less space than the regular per-pixel format. Yields substantially smaller bitmap footprint in many cases. See advanced chapter in manual for details.
  • Slider widget added. See manual or slider_example for more information.
  • Makefiles has been updated to work with make-4.1.
  • Added support for the LPC4088 processor and the Embedded Artists LPC4088 Display Module board.
  • Individual bitmaps can now be placed in internal flash instead of external by having the bitmap file name include the string ".int."
  • MoveAnimator, FadeAnimator and ZoomAnimationImage now have a cancelMoveAnimation/cancelFadeAnimation/cancelZoomAnimation method.

• Update procedure

  • Compatible with existing 4.X applications. Just replace the touchgfx folder.
  • Check Known Issues in the documentation.

• Info

  • The evaluation version of TouchGFX is now distributed with source code for the hardware abstraction layer instead of a precompiled library. This makes it possible to port the evaluation version to custom hardware instead of it being limited to the supported eval boards only. Instead, the evaluation version now has a TouchGFX watermark which will appear occasionally.
  • Memory consumption reduced due to improved rendering algorithm. Will typically allow GUI task stack to be reduced by around 1400 bytes compared to version 4.2.0 (depending on actual application). Additionally the statically allocated memory is also reduced by around 1KB.
  • Maximum number of visible widgets limit of 150 removed.
  • Added two new demos for 640x480 and 480x272 resolutions showcasing new features, graphs, internationalization and custom widgets.
  • Drawable.setPosition() now calls setXY(), setWidth() and setHeight() for easier subclassing.
  • AbstractPainterRGB565 and AbstractPainterBW are recommended as base classes when implementing your own painters.
  • CanvasWidgets now have setAlpha() and getAlpha() methods. Your custom Painter classes must implement this, or inherit from the AbstractPainterRGB565 class
  • Maximum number of registered timer widgets increased from 16 to 24.
  • touchgfx-env updated to 2.4. The environment does not beep anymore.
  • Board Support Package for STM324x9I-EVAL is now based on the STMCubeF4 drivers.

• Bugfixes

  • Screen::handleGestureEvent now converts x/y to relative coordinates
  • Fixed bug when drawing several objects on the same canvas using moveTo() more than once.
  • ZoomAnimationImage movement relative to scaling did not use correct easing equation.
  • PainterRGB565 did not blend green alpha correctly.
  • RadioButtonGroup now initializes callbacks to zero.
  • ScalableImage now works with bitmaps with transparancy.
  • AnimatedImage would display the start and end of an animation twice.
  • Default implementation of CanvasWidget::getMinimalRect() returned coordinates relative to its parent, not itself.
  • ScrollableContainer erroneously unregistered itself as a timer widget at every tick, which made it difficult to use with other timer-based operations.

• Performance

  • ScalableImage and ZoomAnimationImage has been optimized for better performance.

Version 4.2.0

• Release date: January 14th, 2015

• Performance

  • Substantially improved rendering performance, which in most cases will result in a 25% reduction of time it takes to render a frame.

    NOTE: This optimization does not necessarily work on all targets so it must be manually enabled. See the "Optimization" chapter in the porting guide for how to enable this optimization for existing portings. It is STRONGLY recommended that the optimization is enabled. This optimization is enabled for all appropriate evaluation boards in the 4.2.0 board packages.

• Major new features

  • Added CanvasWidgets for smooth, anti-aliased drawing of geometric shapes. Currently Line, Circle and a more generic Shape have been implemented. CanvasWidgets can be painted with a solid color (+ alpha), a bitmap (including alpha) or a custom painter. Read more on Canvas Widgets and Painters in the documentation.
  • Added support for the Keil compiler and uVision4 IDE. Please refer to the "Supported Hardware" section of the TouchGFX Distribution chapter in the documentation for a list of Keil-supported targets.

  • The message displayed when starting a shell has been fixed with correct path to examples.

• Bugfixes

  • Fixed bug in simulator for 1bpp displays when width and/or height was not not a multiple of 8.
  • Fixed bug in ScrollableContainer where CANCEL events where not always delegated to correct child, causing e.g. buttons to remain pressed when dragging outside SC area.
  • Fixed bug when rendering chromArt fonts with a rotated display.
  • Fixed bug - Keyboard widget setTouchable(false) had no effect.
  • Freescale K70 DMA now checks the appropriate DONE bit in TCD0_CSR.
  • On ST processors fixed bug with rotated texts rendered by ChromArt when in non-native display orientation.

• Board support

  • ScalableImage and ZoomAnimationImage now support alpha per pixel bitmaps and alpha per bitmap
  • ScalableImage and ZoomAnimationImage now support ARGB8888 format bitmaps

• Bugfixes

  • Fixed a bug causing the Keyboard widget to render incorrectly in rare cases.
  • Fixed a bug causing drag event coordinates to be incorrect for widgets when placed in a Container with coords != {0,0} which itself was placed in a ScrollableContainer.
  • The Application class now properly keeps track of number of times registerTimerWidget vs. unregisterTimerWidget is called for a given widget, meaning that if registered several times it now requires same number of unregisters before widget no longer receives tick events.
  • Some ZoomAnimationImage functions were not virtual as they should be.
  • Some widgets were missing certain getter functions.

• Update procedure

  • Compatible with existing 4.X applications. Just replace the touchgfx folder.

Version 4.1.0

  • TouchEvent refactoring (API breaking):
    • Drawable::setActive is renamed to Drawable::setTouchable
    • Drawable::isActive is renamed to Drawable::isTouchable
    • Drawable::hijackTouchEvent is deprecated
    • Drawables are now per default not touchables
    • TouchEvents are now always propagated to all containers children
  • Language specific typography and alignment columns support added to text converter. Read more about this feature in the documentation.
  • Font rendering has been vastly improved with regards to font shapes and kerning.
  • Simulator - assert check on new view/presenter/transition size when doing screen transition. Failed assert checks probably due to missing definition of view/presenter/transition in FrontEndHeap.
  • TextArea and ButtonWithLabel now support text rotated 0, 90, 180 or 270 degrees.
  • Text centering on ButtonWithLabel has been improved in special cases.
  • Hardware Accelerated text rendering (4 and 8bpp) on supported ST platforms.
  • Ability to cache all items in the bitmap database in external RAM.
  • Support for Freescales K70 MCU.
  • Translation Sheet: Instances of "\<" and ">" are converted into "<" and ">" respectively. This enables literal translated strings such as "<Not a wildcard>" using "\<Not a wildcard\>".
  • Support for NXP LPC18XX series of MCU's.

• Bugfixes

  • Rendering error of images with odd width and alpha value less than 255
  • Correct handling of TextArea::getTextHeight in case of non initialized textArea

  • ButtonWithIcon optimized draw functionality
  • In extremely rare cases text could be written slightly outside the text area

• Update procedure

  • Due to the TouchEvent refactoring you have to rename functions accordingly. You also need to state in any custom widget or containers if they need to receive touch events. If you were using hijackTouchEvent to prevent children of getting touch events, you now need to make sure that all children is not touchable instead.
  • Main.cpp for simulators need to be updated by replacing the line: TypedText::registerTypedTextDatabase(TypedTextDatabase::getInstance(), TypedTextDatabase::getInstanceSize()) with: Texts::setLanguage(0) You can also specify a specific language from your text database e.g. Texts::setLanguage(GB) In that case you also need to: #include <texts/TextKeysAndLanguages.hpp>
  • Rebuild entire project.

• Info

  • The TouchGFX Manual has been updated considerably.

Version 3.1.0

• New features

  • Added support for FDI uEZGUI-1788-70WVT eval board (NXP LPC-1788 Cortex M3).
  • Added support for Mjolner TouchGFX Demo Board Rev. 1.1 eval board (NXP LPC-4353 Cortex M4/M0 4.3").

• Bugfixes

  • Visual Studio build now rebuild BitmapDatabase.h when new images are added to the assets/images folder.

• Update procedure

  • Only if using Visual Studio: Update TouchGFXReleasePath in your Visual Studio .props file. Simply edit the file in a text editor. The path should be extended with "touchgfx\". See the template_application for inspiration.
  • Only if using Visual Studio: Update your Visual Studio project file (.vcxproj file). Simply edit the file in a text editor. Replace all paths on the form "$(TouchGFXReleasePath)\framework\config\msvs\touchgfx_prebuild.targets" with "$(TouchGFXReleasePath)\config\msvs\touchgfx_prebuild.targets".

• Info

• Hardware Abstraction Layer architecture has been reworked so that all common code for various hardware components (MCUs and drivers) is now shared across different target boards. This greatly simplifies the porting effort for new/custom boards as long as they contain one or more hardware components already supported by TouchGFX.
