I try to drive ST7735 oled display with nucleo board. I worked with a ready-made example I found on the internet, but I could not print anything to the screen. When I compile my code, I don't get any errors and my screen is getting power. Is there a point I missed in the spi settings?
some friends suggested adding spi dma tx, i tried but the result did not change. Do I need to enter an extra parameter in the dma settings?
