Implementation of emulated framebuffer

In this short video, you will learn how to implement the emulated framebuffer strategy. The example is based on the STM32H7S78-DK, but the same procedure applies to other boards that support emulated framebuffer.

The emulated framebuffer strategy leverages a partial framebuffer — usually placed in internal RAM — that is exposed as a full framebuffer by using the GFXMMU. This effectively emulates a full framebuffer.

You wil learn:

• How to set up the GFXMMU
• How to properly configure TouchGFX
• Specific considerations when using the emulated framebuffer on the STM32H7S78-DK
• General recommendations when using emulated framebuffer

Note

Emulated framebuffer is only supported on STM32 MCUs with GFXMMU.
