ESP32-S2 - GPIO 39 not working as ouput?
Posted: Sun Apr 16, 2023 12:52 pm
I'm trying to use GPIO 39 as an output to drive an LED. I know on the ESP32 WROOM that's not possible, but it should be possible on the ESP32-S2. However, the output remains low.
gpio_set_direction(39, GPIO_MODE_OUTPUT);
gpio_set_level(39, HIGH);
What can I do? Is it conflicting with jtag (since IO39 is shared with the MTCK jtag function)? If so, how do I disable this?
