i'm referring to the STM32H7S78-DK which specifically mounts the new STM32H7S7L8 mcu there is the possibility of driving a 1280x400 rgb 888 or RGB 565 tft display using a double frame buffer with reasonable performance we can carry out an example (F...
Hello. I have made a custom project with STM32H735IGT. I use Touchgfx. I am using external flash and external RAM. The problem is when I place the framebuffer in external RAM. Some green pixels appear as in image 1. When I place the framebuffer in in...
Dear all, We are very happy to announce that the new STM32H7R7/S7 graphics line is launched, offering even higher performance and memory flexibility. The main graphics benefits are: 1: Rich graphics features: NeoChrom GPU, LTDC, JPEG Codec, Chrom-AR...
