Please add the DOIT ESP32 DEVKIT V1 / Expressif ESP32 DevKitC to the list of compatible boards

[DurvalMenezes]

Minimum requirements

• Core clock speed is 48 MHz or faster?
• Is the CPU an ARM Cortex M0+ or later?
• Does the host microcontroller have at least 32 KB of flash memory?
• Is the host microcontroller's UART peripheral able to support 420,000 (or higher) baud rate(s)?
• Is your development board currently supported in the Arduino IDE?

What development board would you like me to add?

Please add support for the venerable "DOIT ESP32 DEVKIT V1": https://www.espboards.dev/esp32/esp32doit-devkit-v1/, it's also known as "Espressif ESP32 DevKitC" and by a miriad of other names by other ESP32 devboard manufacturers, all using the no-less-venerable Espressif ESP32-WROOM-32 module.

TIA!

EDIT: forgot to mention, the examples (eg, flight_modes.ino) do compile and upload with no issues. But using the Serial2 port (the only free and unencumbered UART on these boards), serial monitor output becomes garbled immediately upon calling crsf.begin() and from that point on, nothing works. I suspect there's some kind of incompatibility in the way CRSFforArduino uses the serial port, but couldn't figure it out by examining the code.

Espressif have some interesting names for their development boards.
But yea, should be a straightforward one to add. By the looks of things, all I'd need to do is add the board's definitions to the Compatibility Table, and go from there.

There is a bit of a de-facto process I have going on with user requests — especially when I am the one doing the leg work, and that's when I go to do the Pull Request to CFA. What I do there is I'll tag you in the comments section of that Pull Request and you'll need to test it out on your end to ensure everything is working as you expect it to.

Regarding your edit, building CFA with CRSF_DEBUG_ENABLED pre-processor define set to 1 will tell all. It's possible the issue you have mentioned here is because your request isn't yet compatible with CFA. Let's tackle this one step at a time, and if this issue persists after compatibility has been added, feel free to open a separate Issue for this.

Thanks for the prompt response!

Count on it, waiting eagerly for the PR to test.

Just did, and here's everything I see on the serial monitor:

Alright, cool.
I tagged you in #162 with further instructions. We'll carry this discussion over there.

Roger Wilco! Following you on to #162, and closing this one.
