We showed off some fabulous shaped displays last week - and now we're getting them running! This is a 2.1" 480x480 round display with SPI configuration and an 18-bit RGB interface. Thankfully there is already an Arduino library https://github.com/Lzw655/ESP32_Display_Panel that supports the SPI configuration over port expander stuff on this eval board, plus the touchscreen drivers, too - it saved me a lot of time! The chipset is ST7701, a typical TFT panel driver. You definitely have to initialize the display first with the proper configuration before you can blast RGB data for it to show up…
