Hi folks,
i use CubeMX and touchGFX generated code with custom DSI 480x1280 display.
All code works ok , but sometimes display is shifted horizontaly.
70% starts code on and display is pixel 0 to 479 ok.
But 30% starts dispolay randomly shifted and show 60-479-0-59 and rgb is too shifted randomly to gbr or brg. 60 is too random between 30 - 150
I need idea howto solve this.
We use FMC SDRAM and seems as LTDC DSI sync data problem.
Pls help. I attach hwinit cpp file. MCU in main is started and go to sleep
HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);
then wake up by button and go. Code work all ok only GUI is sometimes shifted.
