Accel calibration on 3.3-rc8 vs 3.2

Started Aug 1, 2015 0 Replies

HiMy pixhawk calibrates the accels fine on 3.2 but fails on 3.3-rc8.  I note in the release logs that the sensitivity was increased to 16g - could this be related?  Were the tolerances also…Continue

Decoding the iLap Racing Transponders

If you've been out racing, or used cleanflight, you've probably heard of the iLap racing transponders.  These racing transponders allow racers to be timed around the track using infra-red.The open source community has begun producing free lap timing solutions because many of the commercial options…See More

"Hi My pixhawk accel calibrates fine on 3.2 but refuses on 3.3rc8.  Could this be linked to the acceleration sensitivity being increased? Thanks Gareth"

Build your own Autopilot - tutorial

I have written a tutorial on how to program your own AutoPilot/Flight Controller from scratch using an arduino/ArduPilot/RaspberryPi.  The tutorial will walk you through everything from reading the RC radio and controlling the motors through to how the PIDs are stacked on top of each other to get stable flight.…See More
