Re: gpio_get_level() always returns 0 if pin mode is GPIO_MODE_OUTPUT?

And it was merged into the master branch within 30 hours or so... https://github.com/espressif/esp-idf/co ... 38b69d4807

kudos to espressif for this kind of community engagement and support, thank you.

Re: GPIO32 and GPIO33 on DevkitC V4 (Wroom)

Can you please clarify in which models there is (n)one? DevKitC board (all versions of them) come with ESP-WROOM32 module, not ESP-WROOM03. None of the versions of ESP-WROOM32 came with a 32k XTAL. DevKitC boards don't come with 32k XTAL installed either. Oh, I was not aware that "03" was a model n...

Re: What would you like to see in The Next Chip?

Two things are certainly important for many people: on-chip flash and/or more usable GPIOs. USB Integration of LoRa would be awesome, more GP timers would be useful (although there are already some peripherals that can be used to implement what is done with GP timers on other devices like pulse coun...

Re: gpio_get_level() always returns 0 if pin mode is GPIO_MODE_OUTPUT?

I fell for this today as well. The API documentation states "GPIO get input level." This is a good hint but could be made way more obvious. I made a merge request to improve on that: https://github.com/espressif/esp-idf/pull/1740

GPIO32 and GPIO33 on DevkitC V4 (Wroom)

Hi, I was unable to confidently derive from (the schematics in) the documentation if there is a 32kHz crystal attached to the RTC GPIO pins 32 and 33 of the ESP32 DevkitC V4. In earlier versions of the Wroom datasheet (ESP-WROOM-03 Specifications, Version 1.0, 2015.12) there is one depicted but not ...
