Questions About Animation Storage

[V.H]

Hi,

virtual void setFrameBufferStartAddresses(void* frameBuffer, void* doubleBuffer, void* animationStorage)

1, Parameters frameBuffer and doubleBuffer can generated by CubeMX, animationStorage parameters can also be generated by CubeMX ?

2, I don't use the animationStorage parameter and the animation of the Icon will play normally, when will the animationStorage buffer be used ?

3, How to determine the size of parameter animationStorage, does it have to be equal to the frame cache size ?

Hi,

1. The animationStorage cannot be generated by STM32CubeMX. If I remember correctly this was done to prevent malpractice since it is not necessary for most UIs and requires available memory.
2. The animation storage is mostly used for the screen transition "Slide transition". It is not necessary for texture mapper animations.
3. It must be the same size as a framebuffer, so Width * Height *bpp/8
