I am attempting to develop an FSK transceiver for the SI4463 and an ATmega328p in C. An OOK transceiver would certainly be a start.
As popular as it is, I cannot seem to find much, if any documentation on the device.
I can't figure out how to initialize the registers, switch the transceiver between Rx/Tx, or even write to the FIFO buffer.
The datasheet is no help. I found an API but that isn't much help.
Any info is much appreciated.
