ESP32-R3 touch - GPIO pins?

Postby apepper » Fri Dec 23, 2022 4:05 pm

Hi all, I'm working on a project using the ESP32-R3 with display and touch. The question is, what GPIO pins can I safely use? I can't find a pin out diagram of the board - can someone point me in the right direction?

TIA

I've found the pinout (on the website, duh!), but most of the GPIO pins are labelled "touch" - does that mean they aren't available for general use? In an ideal world, I'd like to use the SPI pins.

I think we do not have a chip series called " ESP32-R3 ", please figure out which chip do you use. Then please read chip datasheet, you will find a chapter called "Peripheral pin configurations ", you could know how to use GPIO for different peripheral.
