[yukang]

hello everyone i'm a beginner here,i have successfully using my DIY board to that the SPI LCD work without TouchGFX the color and reaction was great.

MCU:stm32wb5mmg

LCD driver:st7789

Display:240x240pixels,RGB565

now i want to use TouchGFX in this project, i try the stm32wb55RG NUCLEO AZ1 demo

project in TouchGFX with stm demo board and it work perfectly,i notice the demo board

have the TE pin and external FLASH memory(MX25L6433F)that my DIY board don't have.

Is there possible to use touchgfx in my DIY board(without TE pin and external FLASH memory)?

If you dont plan super smooth quick animation TE isnt required for SPI

and external flash is required if your graphics resources oversize internal flash.

Good optimized gui no problem.
