ESP32 GPIO Config

Postby owen_chen » Fri Sep 07, 2018 2:39 am

Hi:

Does any GPIO of ESP32 could be configured as UART/SPI/I2C by software?

Yes. Note that some pins are already in use for other things (e.g. the GPIOs the flash is connected to) and some GPIOs are input-only; aside from that, the GPIO matrix allows you to use any pin for these functions.
