ESP32 failed to configure gpio

Postby Marco_daikoo » Wed Jan 15, 2020 5:27 pm

I have development modules based on the Esp32 Wroom 32 with 38 pins.
I can run several programs, so far so good.
I used Uart2 and Uart0 normally.
Until I went to use Uart1. I noticed that the pins on this port cannot be set. I tried to turn on leds to do a simple test and not even the leds could be configured.
I realized then that these pins belong to a group of pins that comprise in SD0,1,2,3, CMD and CLK. I went to run the led test and it doesn't work on any of these pins. on all other module pins work.
I'm using the Arduino IDE, what can I do to fix this?
