Temperature probe

MWOSD now supports a directly connected hardware temperature sensor - LM35

Configuring MWOSD - non Mavlink users

By default the temperature support is enabled in MWOSD from 1.8.2 onwards.

Configuring MWOSD - Mavlink/Ardupilot/PX4

• MAvlink provides temperature within its data stream from the FC.
• If this is not a sensor reading required, a directly conencted LM35 can be used.
• To enable this, a custom install with Arduino is required.
• #define HARDWARE_TEMERATURE_LM35 will need to be enabled in config.h

Hardware Connection

• Connect the LM35 as per the diagram at the link below.
• The default "Aux" pin is A1 - or Amperage pin on the minim OSD hardware. For Aeromax hardware this is the Aux pin A6 which is the pin furthest away from BAT1 pin

Configuration options - config.h

#define TEMPERATUREMAX 50 // Temperature warning value #define TEMPCAL_0 0 // Calibration value for 0 degrees C (range = 0-1024 as per arduino analogue) #define TEMPCAL_100 931 // Calibration value for 100 degrees C (range = 0-1024 as per arduino analogue. 931 = 1v for a 1.1v reference)
