ESP32-C3 Dedicated GPIO

Postby dwhire » Sat Jan 29, 2022 9:00 am

The example: examples\peripherals\gpio\matrix_keyboard does not compile. There seems to be a problem with the Dedicated GPIO Configuration. One of the error messages is: DEDIC_GPIO_INTR_NONE' undeclared
I ran idf.py set-target esp32c3. Did I miss something in memuconfig?

I experienced this problem on both ESP-IDF version 4.3 and 4.4.

Ah, I think I see the issue. The C3 does not have interrupt support for the dedicated IO, so that example is not compatible.
