Devin Alexander / SX1276GenericLib

I made a fork of a generic library that was developed with support for RFM95 LoRa module that I found online. I Made a few changes and made it compatible with hardware limitations of the MAX32620FTHR and MAX32630FTHR module.

Dependents:   MAX326xxFTHR_LoRa_RFM95 MAX326xxFTHR_LoRa_PingPong MAX326xxFTHR_RFM95_LoRa_PingPong MAX326xxFTHR_LoRa_RFM95_PingPong_Example ... more
