Detailed Description

Data acquisition module for ENAC PTU board.

provides meteo data:

• temperature
• humidity
• absolute pressure
• differential pressure

based on the ADS1220 spi ADC for pressures and temperature, and PWM input for humidity

data can be send other telemetry and/or logged on SD card (on capable autopilots)

designed and debugged by Michel Gorraz and Alexandre Bustico @ Enac (2014)
