"Great work, thanks for posting this John. To improve accuracy, we could store the high res data on a PC or cellphone and send relevant sections to the UAV as needed. Perhaps a MAVLink/QGC extension is in order."
Hi Everyone,I'm testing Madgwick's quaternion DCM C code with a Sparkfun 9DOF sensor stick. It's oscillating a lot due to the accel integral term (like 5-10 degrees peak-to-peak, lasting for minutes).I know the idea is to keep the P gain low, so…
"And it's not so easy to convert current to prop RPM, let alone air speed. 5A may mean the prop is running at a constant 2000 RPM, or accelerating from 100PRM to 200RPM. I suppose if you considered the commanded throttle too, you could design a…"
