I want to use touchGFX on STM32L496G-Disco with a screen connected to spi1 and not the on board screen.

I want to use touchGFX on STM32L496G-Disco with a screen connected to spi1 and not the on board screen.

the screen connected to spi1 is supported on another board with the driver in ST7789.c + .h when it is connected to STM32L476RG_NUCLEO. the problem I have with this board is that touchGFX can't run on it because of small ram size.

I tried to switch to this driver, but I had problems to change the TouchGFXHAL.cpp . I don't know what should I do with this layer.

thanks.

320KB of RAM is ok, then maybe you make other mistake.

hello. if ram is ok with STM32L476RG , how can I add touchGFX to the project made by cube MX ? thanks.

also, if I try to use STM32L496G-Disco with the other screen I want, how can I set touchGFX to run on this other screen ? thanks.

hello. I have a project that support ST7789H2 screen and I need to change to ST7789 screen that I connected through SPI.

I have to set TouchGFXHAL properly. Is there an example for TouchGFXHAL that use ST7789 ?

thanks.
