Function for effectuating a screen transition (i.e.

makes the requested new presenter/view pair active). Once this function has returned, the new screen has been transitioned to. Due to the memory allocation strategy of using the same memory area for all screens, the old view/presenter will no longer exist when this function returns.

Will properly clean up old screen (tearDownScreen, Presenter::deactivate) and call setupScreen/activate on new view/presenter pair. Will also make sure the view, presenter and model are correctly bound to each other.

Template Parameters:
ScreenTypeClass type for the View.
PresenterTypeClass type for the Presenter.
TransTypeClass type for the Transition.
ModelTypeClass type for the Model.
Parameters:
currentScreenPointer to pointer to the current view.
currentPresenterPointer to pointer to the current presenter.
heapReference to the heap containing the memory storage in which to allocate.
currentTransPointer to pointer to the current transition.
modelPointer to model.
Returns:

Pointer to the new Presenter of the requested type. Incidentally it will be the same value as the old presenter due to memory reuse.

Simple implementation of the standard memset function.

Will write the value of 'c' in 'size' consecutive bytes starting from 'data'.

muldiv

int32_t muldiv(int32_tfactor1 ,
int32_tfactor2 ,
int32_tdivisor
)

Multiply and divide without causing overflow.

Multiplying two large values and subsequently dividing the result with another large value might cause an overflow in the intermediate result. The function muldiv() will multiply factor1 and factor2 and divide the result by divisor without causing overflow (unless the final result would overflow). The remainder is used to round the result up or down.

Parameters:
factor1The first factor.
factor2The second factor.
divisorThe divisor.
Returns:

(factor1 * factor2) / divisor rounded.

See also:

Location: touchgfx/Utils.hpp

Multiply and divide without causing overflow.

Multiplying two large values and subsequently dividing the result with another large value might cause an overflow in the intermediate result. The function muldiv() will multiply factor1 and factor2 and divide the result by divisor without causing overflow (unless the final result would overflow). The remainder from the division is returned.

Parameters:
factor1The first factor.
factor2The second factor.
divisorThe divisor.
remainderThe remainder.
Returns:

(factor1 * factor2) / divisor.

Note

For large numbers close to the limit of int32_t, the calculation may not be correct.
