This is a port of the RFM69 library for arduino from https://github.com/LowPowerLab/RFM69 to python for raspberry pi.
Attach the RFM69 as follows:
| RFM pin | # | Pi pin header description | Pi pin header description | # | RFM pin |
|---|---|---|---|---|---|
| 3v3 | 17 | 3.3V Power | (GPIO24) | 18 | DIO0 |
| MOSI | 19 | MOSI (GPIO10) | GND | 20 | Ground |
| MISO | 21 | MISO (GPIO9) | (GPIO25) | 22 | |
| CLK | 23 | SCLK (GPIO11) | CE0 (GPIO8) | 24 | NSS (CS) |
| Ground | 25 | GND | CE1 (GPIO7) | 26 | |
| 27 | ID_SD (N/A) | ID_SC (N/A) | 28 | ||
| RESET | 29 | (GPIO5) | GND | 30 | Ground |
You can change the interrupt pin (GPIO24) in the class init.
Remember to choose correct frequency for your hardware (315, 433, 868 or 915 MHz).
RPi.GPIO and spidev
If you are using newer firmware you'll need to get a newer spidev, the old one is no longer working:
git clone https://github.com/Gadgetoid/py-spidev
cd py-spidev
sudo make installAnd don't forget to enable the SPI interface:
sudo raspi-configSelect "Interface Options", -> "SPI", choose "Yes" to enable it and reboot.
sudo reboot
