The transceiver present on the TeensyWiNo is a HopeRF RFM22b (datasheet).
The RadioHead RH_RF22 examples must be modified to be executed on the TeensyWiNo board:
- Teensy SPI clock pin must be set to pin #14
- Teensy SPI CS pin must be set to pin SS
- Teensy SPI IRQ pin must be set to pin #9
Here is the good configuration in the Arduino sketch: On the RH_RF22 constructor:
In the setup(), before calling rf22.init():
With these two modifications, all RadioHead RH_RF22 example sketchs are operational.
