Is there any way I can test the barometer component?
My APM 2.5 was working well until yesterday, when the barometer altitude began reading -22 million meters. The GPS altitude is correct.
I've not changed anything major, and not had any serious crashes, so I'm wondering if the part is bad.
I'm running Arducopter 2.9.1 in a 3DR Quad.
I've run the altitude test from the CLI in Mission Planner. Here's what I got:
alt: 0cm, pres:99731mbar, temp: 309/100degC, raw pres:8772901, raw temp 8128156
