LCD screen flashing on STM32H747 Discovery board with BSP library

[Pouya Rostam]

Hi folks,

I am trying to create a simple GUI with the BSP library on a STM32H747-Discovery board. Everything works fine till I increase the lcd refresh rate to around 30 Hz, then I see some flickering. Does anyone have any idea on this issue?

Also, I wanna know if there is a way to use "double buffering" in BSP library.

Thanks,
