RFM69 library in C for Raspberry Pi
This is a port of the RFM69 library for arduino from https://github.com/LowPowerLab/RFM69 to C for raspberry pi.
Some ideas are included from the python port from https://github.com/etrombly/RFM69.
Attach the RFM69 as follows:
| RFM pin | Pi pin |
|---|---|
| 3v3 | 17 |
| DIO0 | 18 (GPIO24) |
| MOSI | 19 |
| MISO | 21 |
| CLK | 23 |
| NSS | 24 |
| Ground | 25 |
| RESET | 29 |
You can change the interrupt pin (GPIO24) and the reset pin in the initialisation.
Remember to choose correct frequency for your hardware (315, 433, 868 or 915 MHz).
