I bought a prebuilt Megadesk module, connected it to a ESP32 and flashed that using esphome and the provided yaml file.

I get the following logs:

But as i don't know what the communication is supposed to look like i don't know if that helped at all.

Are the UART answers as you would expect ?

Does the default firmware of prebuilt tindie modules have UART included ?
The more i debug this it just seems like nothing but interference gets recieved by the esp.

More logs (no logic level invertion), but logging as hex, not strings:

[00:25:00][D][button:013]: 'Desk Position 2' Pressed.
[00:25:00][D][uart_debug:114]: >>> 3C:4C:30:2C:32:2E
[00:25:00][E][uart:015]: Reading from UART timed out at byte 0!
[00:25:00][D][uart_debug:114]: <<< 58:3B:00:68:FE:81:00
[00:26:02][D][button:013]: 'Desk Position 3' Pressed.
[00:26:02][D][uart_debug:114]: >>> 3C:4C:30:2C:33:2E
[00:26:08][D][button:013]: 'Desk Position 4' Pressed.
[00:26:08][D][uart_debug:114]: >>> 3C:4C:30:2C:34:2E

Odd that your logs are being printed as hex, possibly a bug with the ESP32 build.

Unless @gcormier changed it since the v2021.09 build, serial is not enabled on the shipping boards.

If you don't have any programmer to flash a different firmware onto the megadesk controller, then you could try using https://github.com/ESP32-Musings/OTA_update_AVR_using_ESP32. I have not tried or used it, but it may be worth a shot before purchasing a programmer.

Phil is correct - the serial firmware is not flashed by default.

What are the reasons for not compiling it in the default firmware ?

The solution by @tagno25 requires bidirectional voltage shifters, which i don't have at my current location :/

Probably due to the chip shortage i can only find knock-offs of the AVR Programmer recommended in the DIY section for twice the price in germany😐

So i guess my Megadesk project needs to be delayed about 6 months when i am back at this location.

Thanks anyways :)

Most people do not use serial, and I want the board to be as stable as possible for those people. Anyone comfortable to solder headers and play with the secondary MCU are likely able to flash megadesk with a bit of light reading in the worst case.

I found a different AVR programmer in stock and it worked :) Thanks for this awesome project.
