Add FSK/OOK compatibility to Driver #55

Open lgnashold opened 3 years ago

lgnashold commented 3 years ago

I am working on using the RFM98PW on a satellite, and as part of that, I will need to leverage the OOK capabilities of the radio module to transmit an easily-understood beacon. To do this, I have been working on adding FSK/OOK capabilities to the RFM9x driver.

I have been working on a barebones implementation on a fork, although it needs more testing and probably more configuration. I have been mostly targeting OOK, although it shares a lot of overlap with FSK.

I have a few questions regarding this:

I plan to update this issue as I go, as well as create a PR when the code is in a more mature state.

Would this be functionality that adafruit would be interested in merging into this repo (or separating into a completely separate driver)?

Sure - I'd like to see how you're implementing it in user-code to determine if we should organize the files further.

Could you add an example to that fork?

Would people who are more familiar with either the specific module or radio use in general be able to provide feedback on my code as I write it, since I am still relatively new to radio hardware and CircuitPython?

Yep! Please tag me when you open up a Pull Request.

Just curious -- If this works would you expect it to be possible for an RFM9x to talk to an RFM69 if both configured for FSK?

@lgnashold Did you ever get your FSK/OOK fork working? I need FSK for a satellite project and I am not getting any errors after running your code on a PyCubed board with an RFM98 but it does not seem to be transmitting anything.

I tried with both self.modulation_type = _OOK_MODULATION and self.modulation_type = _FSK_MODULATION

FYI - I do have FSK working on teh RFM9x and it can communicate with an RFM69 module. I am working on a new library that combines the RFM69 and RFM9x libraries and adds some options.( FSK for RFM9x, headerless (no radiohead header). It is still a "Work In Progress" https://github.com/jerryneedell/CircuitPython_RFM
