External sensor data through mavlink

Posted by Raibrinder Gohalwar on July 7, 2014 at 6:19am

Hi,

I am trying to get an IR temperature sensor mounted on my copter to send back live data through a designated parameter through mavlink. The sensor has an option for analog or spi outputs for the signal. I have the pixhawk on board and have the spi port available.

I would love if someone out there with the knowledge could help me. Or at least guide me on the right path.

Here is a simple example using the ADC3.3 port.

To simplify things I have used an existing mavlink message that contained data that I am not currently using (sonar_alt). This is contained in the RANGEFINDER message (id=173)
