Partial Frame Buffer & Slide Transition

[kumaichi]

I'm using an STM32U535 and ILI9341 touch display for my project.  I have the screen up and the touch control working with 5 screens, using forward/back buttons to navigate.  The simulator shows the slide transitions correctly but when I push it to my board, there are no slide transitions with selecting the buttons.  I've done some searching and it appears that I don't have any memory allocated for the animation buffer.  Which leads me to my question, how do you implement/allocate memory when a partial frame buffer is being used?

In my research, I need to call the, setFrameBufferStartAddresses() method in the TouchGFXGeneratedHAL::initialize() method.  My initialization method is considerably different than what I've seen:

// Block Allocator for Partial Framebuffer strategy
static ManyBlockAllocator<2048, /* block size */
       3, /* number of blocks */
       2 /* bytes per pixel */
       > blockAllocator;

void TouchGFXGeneratedHAL::initialize()
{
    HAL::initialize();
    registerEventListener(*(Application::getInstance()));
    enableLCDControllerInterrupt();
    enableInterrupts();
    // Partial framebuffer strategy
    setFrameBufferAllocator(&blockAllocator);
    setFrameRefreshStrategy(HAL::REFRESH_STRATEGY_PARTIAL_FRAMEBUFFER);
}

I tried creating some of the examples in TouchGFX but can't seem to find a sample that uses the partial frame buffer with slide transitions.

Any insight would be greatly appreciated.

Kindest regards
