First round touch display working with ESP32-S3 ๐Ÿ‘‰๐Ÿ”ด๐ŸŸข๐Ÿ”ต
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, but we were able to noodle that together here https://github.com/ladyada/ESP32_Display_Panel/blob/master/src/lcd/ST7701.cpp#L37, and now it's looking great. Now we know this display and touch setup works, we'll start ordering the displays for us to stock and use.
