Waveshare esp32-s3 2.1 touch

[themagicm]

Anyone have an example code that works with this device?

[tobozo]

the wiki has a some demo code both for esp-idf and arduino

however there is no existing LGFX config for this device, so you'll have to build your own.

you can use this configuration example as a basis:

• keep Panel_ST7701 section
• replace Touch_GT911 with Touch_CST816S
• edit the pin numbers to match those from the wiki

So the 816S is compatible with the 820 that is on this display? Sent from Proton Mail Android

hi @themagicm, have you make it work? I'm doing the same but still not work, confusing with EXIO_Init
