A node-red node for sending and receiving through RFM69 radios on the Raspberry Pi.
Wraps the rfm69radio code.
This version tested on a pair of Adafruit RFM69HCW Radios with this node-red running on a Raspberry Pi 3 Model B.
The default wiring is:
| RFM pin | Pi pin |
|---|---|
| 3v3 | 17 |
| DIO0 | 18 (GPIO24) |
| MOSI | 19 (GPIO10) |
| MISO | 21 (GPIO09) |
| CLK | 23 (GPIO11) |
| CS (NSS) | 24 (GPIO08 CS0) |
| Ground | 25 |
| RESET | 29 (GPIO05) |
See here for the Raspberry Pi 3 GPIO pins.
The second radio is connected to an Arduino UNO running the code in frm69_test.ino and connected according to the instrucitons from Adafruit.
