I have a 7" RGB LCD 1024x600 32bits framebuffer, the pixel clock is 51.2MHz for 60fps recommended in the datasheet.I tried to interface this LCD with an STM32H743i-EVAL2 board, which is working fine, until I began to try using 2 layers of 32bits (for...
Hello,I have 2 EVAL board, one STM32H743i-EVAL2 and one STM32H7B3i-EVAL.Both have the same NOR Flash chipset MT28EW128.I'm using the function HAL_NOR_ReadBuffer to read data from the NOR.but, "sometimes", the data I read are corrupt.I made my project...
Hello,I'm using an STM32H743i-Eval2, we plugged in another LCD of 1024x600 RGB888 60HzWe set the LTDC clock at 51.2Mhz as written in the LCD datasheet. (HSE 25Mhz / 25 * 512 / 10)We get no clock at all on Pin32 of CN20 (CLK pin on LCD connector)The c...
Hello,I'm using an STM32H743-EVAL2 board, I want to access the LCD screen to draw a PNG image, so I'm using a png library to load the image, and this library use "malloc".Unfortunately the RAM of the H743 is too small for handling large pictures, so ...
I bought a STM32H743I-EVAL2 board and updated to the latest STM32Cube 1.8.0 with firmware V1.9.0 and V1.9.1I tried 2 examples project and they both shows graphics issues.The example "DMA2D_MemToMemWithBlending" show the 2 first image incorrectly (the...
