hi,I have successfully connected LTDC display(480x272) with STM32H723ZGT6 - RGB565 mode .I could able to image file from internal Flash Memory .I could able to Load Perfect colour from DMA2D by using. framebuffer in global level .uint16_t framebuffer...

hi,I am trying to connect ili9341 - STM32F722ZE FSMC- TFT but i couldn't succeed .ili9342 16bit - is working in direct GPIO 16 bit data PORT drive with STM32F722ZE not in FSMC-TFT . Looks most of the ili9341 working with FMC-TFT STM32F4 Series aro...

hi1. STM32F722ZE & Winbond SDRAM is working fine with follow setting .W9825G6KH-6I 166MHz/CL3 or 133MHz/CL2 CASLatency = FMC_SDRAM_CAS_LATENCY_3; SDClockPeriod = FMC_SDRAM_CLOCK_PERIOD_3;my understanding was MCU main clock was divide by 2 is made o...

@SofLit @Tesla DeLorean Hi,Problem is with the DMA incorrect data is coming and Without the DMA is working properly .I do agree with MCU pins (Nucleo Board) and SDRAM PCB pins connected via the jumper wire might be cause.at this movement my quest...

hi,i was used stm32f446re . Using ULPI interface for HS operations on STOP Mode will be solution . ( not USB related )Currently working on stm32f722ze and going to add stm32h7b0 power saving is essential in any series . Hope your suggestion will...
