Espressif does not control additions to platformIO. You need to contact them to see if they are willing to add it. Does that mean I can't use PlatformIO to write programs for a board that I design? That doesn't sound right. I was thinking that I would need to make some new description file that wou...

I've built my own ESP32C3 board. How do I use it in PlatformIO? (VSCode) I have already tested it in Arduino IDE and I can program it and see that it works, but I don't get access to the serial communication via the built-in JTAG. I am trying to see if I can do so with platformIO, but PlatformIO onl...

Awesome, thank you! I still can't make any serial writes to the console. The console is empty. (I'm using Arduino 2.0 IDE for now for simplicity, but will eventually be using Platform.io, if that makes a difference). Is there anything I can do to get the serial monitor to work over the USB JTAG? Tha...

It's odd, I don't do anything with pins 18 and 19, but doing some simple networking, and that knocks the connection over the USB off. I've since been testing other things and everything else is working: I have an LED, a couple of interrupt lines that I can trigger, a piezo, etc. The USB JTAG/serial ...

Thank you!

For a brief moment the device showed up on my Mac with as a "USB JTAG/serial debug unit". I tried uploading a simple sample (SimpleTime), and after that I somehow must have screwed up the state of the GPIO18 and 19 pins, and now I don't see the device on my Mac anymore. Any ideas?

I've connected my ESP32C3's GPIO18 and GPIO19 to the USB connector in the hopes that I can directly communicate with it over USB. I am not sure what the next step is. Do I need special drivers? What are the use cases for this? Can I use those pins/USB for uploading programs, or am I only limited to ...
