How-to

Hi guys,

I’m trying to use the UART of the Waveshare ESP32-S3-TOUCH-LCD-7, but I don’t know what the pinout or Serial[n] is to do this.

Can anyone help me to solve this issue?
Please, post the code for me to send String number from 0 to 10 with 1 second delay.

Tell me if it is necessary to change item 15.

Thanks.

i believe that board uses CDC and not a UART. the CDC operates on pins 19 and 20. You would need to set up the ESP-IDF so USB-CDC is turned on.
