Good afternoon to everyone!I have some problem with flushing or rendering.My settings:partitial framebuffer, 4 bloks, 16bpp, 32000 block size;internal RAM for framebuffer;use DMA2D and DMA2 for FMC (STM32F469);Problem - after start UI if we press "Re...

Hello everyone!I find out that framebuffer allocator working with issues. If we use 4 bloks, counter sendingBlock or drawingBlock lags and we draw another blocks. TouchGFX engine marks another block. markBlockReadyForTransfer() we call in flush met...

I am add code in function transmitFrameBufferBlock delay before start DMA for FMC:void transmitFrameBufferBlock(uint8_t* pixels, uint16_t x, uint16_t y, uint16_t w, uint16_t h) { _isTransmittingData = 1; uint32_t _data_length = w * h; ...

Why not call buttonCallbackHandler in touchGFX?

How to configurate my custom project with TouchGFX engine and design for STM32F4 (I am use RTOS) with LCD controller SSD1963 over 8080 interface (i am not use DMA)?
