I tried copying some code online to make my I2C ST7735 display work. I thought it was SPI because it worked with SPI on Arduino. It's I2C so it's behaving weird with my USART_MSPI. I don't know if I've got something wrongly configured or not, but I'd like to know if there's a library with test examples for this display so that I can test the SPI code and then change it to work as USART_MSPI and later on USART_MSPI+DMA for scanline-by-scanline rendering.
