mf_ptu
PTU board from Meteo France (pressure, temperature, humidity). Raw meteo data: - Pressure in ADC - Temperature in ADC - Humidity in micro-seconds (period of the input signal) When using SEND_PTU flag, scaled pressure, temperature and humidity data are sent over telemetry with the PAYLOAD_FLOAT message (array of float). If scale factors and offset are not specified, raw values are sent (scale=1.0, offset=0). When using LOG_PTU flag, raw pressure, temperature and humidity data are stored with raw gps data (position, speed, time, status). Field names and units are in the first line of the log file.
