I have a device that has a very non-standard serial interface. It uses something like 10-bit serial at 100 kHz.

On my logic analyzer, it looks like:

Is it possible to configure the UART to read this data format?

I'm currently trying to bitbang a solution, but I'm running into timing problems and would be much better if I could configure the UART to handle this instead.

Maybe look into the RMT peripheral...

Good call! I tried using the RMT peripheral today and creating a custom tx encoder and it works well.

Just need to figure out rx decoding.
