This is the firmware for the Rc receiver based on the SX1280 chipset. The hardware design can be found here: Rc Receiver
- Handle both receiver and transmitter in one codeline
- FHSS (Frequency Hopping Spread Spectrum) system
- FCC and ETSI EN compliance
- 80 channels (on normal ISM band: 2400 Mhz - 2483.5 Mhz), with 1MHz channel separation
- 100 Hz hopping frequency
- Fixed hopping sequence
- Simple acquisition and tracking between the transmitter and receiver
- No binding process the transmitter and receiver hard-bound together
- Fixed packet length
- Transmitter sends basic control functions
- At least 16; 12 bit channels
- Receiver can also send telemetry data back
- RSSI (Received Signal Strength Indicator)
- Receiver battery voltage
- Built in GPS support
- Extensible via UART port(s)
- OTA (Over the Air) firmware update
- The firmware is using both RF modules
- FHSS works
- Acquisition and tracking works
- Communication is only one way at the moment
- (Code is a bit messy, just made it work)
