Thanks for the reply. I'm not much good with software either (or hardware! :roll: ) I think I'm going to try I2C rotary encoder boards. They should only need one (interrupt) pin each, which hopefully will work with the JTAG pins that are functioning. I've had an OLED display running on the I2C heade...

I don't understand this, as the hardware reference says that (after JTAG is enabled)

Vol- touch button is not available for use with the API

So surely Pin 13 should be available for me to use too?

Is anyone here from Espressif who could explain this?

Thanks, Peter

Thanks for the reply. I think the SD card is disabled with the DIP switches in that configuration, so Pin 15 should be okay? Yes, the 'Allocation of ESP32 pins' section of the Hardware Reference doc says that Pin 13 is also used for the Vol- touch pad. Presumably this is the issue. Is there any way ...

Hello, I am trying to use the JTAG header pins as GPIO pins on a Lyra-T board. I have switched the DIP switches as per the Hardware Ref to enable JTAG (DIP switches 3 to 7 ON). I want to run two rotary encoders using the four available pins (earth being provided on a power rail). I am using the ESP-...
