ST7789 + F767ZI Nucleo
Posted: Fri Feb 18, 2022 1:59 am
All I want to do is wire up an ST7789 to my STM32 black pill board, over SPI.
I've wired it into SPI1, based on the multiple pinouts I've found online.
I use the "SPI" instance of SPIClass in arduino to talk to it.
I GET NOTHING.
Just the backlight.
I've done this fine for ESP32s, and Arduinos, and other MCUs. The only ones that give me trouble are the Nucleos.
I've got two of them, and they have caused me nothing but headaches.
Which pins are SPI? Which pins connect to the SPIClass instance named SPI under Arduino, FFS? This shouldn't be this complicated.
