Initial DFM17 support (closed and abandoned) #53

Closed kd2eat closed 9 months ago

kd2eat commented 9 months ago

This code should compile for both DFM17 and RS41, and run on the RS41. There's an IFDEF at the top of config.h to select whlch build. Lots of work to be done at the hal layer, but it's a start.

Note, as I try this PR, it claims it wants to merge it with your "main" branch. Hopefully, when you accept, you can accept it into a different branch.

Do I understand that progress is being made on uploading Amateur Radio code to the DFM-17 platform? That would be GREAT news - I already have one and there are many more DFM-17s potentially available in my area than there are RS-41s (which I've unfortunately not recovered yet). Do I read this correctly? I'll be glad to test when you all say it's ready to try on a DFM-17.

Thanks!

@K4KDR Yes, we are trying to get at least the simpler modulations like Horus 4FSK working on DFM17s. @kd2eat has been doing great work to get the code running on a DFM17, next there is the work to support the radio chip, which is the only major difference.

We will gradually add complete instructions on how to flash and configure DFM17s with this firmware.

Abandoning this version. It turns out that Si's provided driver code is copyrighted. We need to work from a different driver base.
