Re: Pull up does not work.

Hello @Saichander have a look here: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/gpio.html . GPIO34 to GPIO39 don't have internal pull-up (or pull-down) capabilities. Excerpt from that page: GPI: GPIO34-39 can only be set as input mode and do not have softwar...

Re: ESP32-C3 deep sleep GPIO wakeup reason

Hello @andrewandroid which ESP-IDF version are you using? Running the provided deep sleep example https://github.com/espressif/esp-idf/tree/master/examples/system/deep_sleep on my ESP32C3 works fine and I get the proper wake-up reason. I tried with the latest ESP-IDF from github, e.g. 5.2.x. Thanks ...

Re: Interal Pulldown not working on GPIO19?

Hello @sircastor from the ESP32C3 datasheet: https://www.espressif.com/sites/default/files/documentation/esp32-c3_datasheet_en.pdf USB - GPIO18 and GPIO19 are USB pins. The pull-up value of a USB pin is controlled by the pin’s pull-up value together with USB pull-up value. If any of the two pull-up ...
