Code running on the navigation board, preliminary version running on an Adafruit Feather M0 with RFM95 LoRa.
Additional hardware:
- NXP MPL3115A2 connected via I²C
- Pitot Tube with NXP MPXV5004DP Sensor connected to ADC 0
- SRF02 connected via I²C
The UART-Baud Rate is 115200.
The output package is a 11 bit, 4 Channel Package with the following data:
| Channel | Data |
|---|---|
| 0 | RSSI of the last package |
| 1 | Altimeter Data (Capped at 2047) (m) |
| 2 | ADC value of the pressure sensor for the Pitot-Tube (0-1023) |
| 3 | Ultrasonic Distance (cm) |
All data that is received via LoRa is directly forwarded, all data that is sent to the Navboard is forwarded as well.
