MWOSD now supports a directly connected hardware analogue airspeed sensor - MPXV7002DP
- By default the hardware airspeed support is disabled in MWOSD.
- If this is not a sensor reading required, a directly conencted MPXV7002DP can be used.
- To enable this, a custom install with Arduino is required.
- #define USE_AIRSPEED_SENSOR will need to be enabled in config.h
- Ensure the reference voltage is set to 5v.
- Mavlink and iNAV provides airspeed within its data stream from the FC.
- Directly connected airspeed sensor is not supported. Do not enable.
- Calibration values may need to be adjusted. Dafaults are approx values.
- Adjust "AUX zero calibration" to get correct calibrated zero value airspeed . Use 512 as starting value
- Adjust "AUX calibration" to get correct calibrated airspeed. Use 500 as starting value
- Note typically, airspeed is set to zero when in disarmed / non flying state
- Connect the mpxv7002dp as per the diagram at the following links:
- Generic connection diagram
- The default "Aux" pin is A1 - or Amperage pin on the minim OSD hardware.
- For Aeromax OSD hardware the Aux pin is A6 leaving Amperage pin free.
