Thanks to:
- Salim CHIAD F4IFB (@schiad) who encouraged me a lot to start this project, he made some very useful functions like sending data to the transmitter registers or a function that translate frequency into the coorresponding register instruction.
- Jarek Surmacz (@infrat) who I think made the first opensource project on the M20, a simple thing that collect GPS data and print it to serial TX, it was inspiring for our first sandboxes.
- Tobias and Matthias who did an incredible M20 Reverse Enginering work on their personnal blog.
