Hi everyone!,
I am working with the STM32 MCU family. I have some TFT with different graphics drivers (1.8 "ST7735 - 2.4" ILI9341). I tried the wiring and everything works fine.
To draw text on a background image, I want to save the background image area to redraw it when I delete the text. None of the graphics drivers has this option. I am thinking of using an external SRAM, an SPI.
Do you think it is a good idea? Is there a better way to do this?
