I am flying with RP3/Navio2 on two different quad frames with the latest stable emlid image AC-3.4.
Two days ago I installed the latest AC-3.5-rc2 and built on the RP3 itself, then reset to defaults the
parameters from MP 1.3.45.1, set FRAME_CLASS to 1 and made usual settings and calibrations.
After RP3/navio2 & ESC initialisation there are erratic outputs to the ESC/Motors, even when Disarmed.
I can arm and power on motors but there are still erratic spikes.
If I return back to AC-3.4 with the same setup it’s working fine again.
I tried three different ESCs: Typhoon 4-in-1 20A BLHeli 14.4, Littlebee Mini-20A BLHeli 14.1 & DJI 620S
In BLHeli: ‘Enable PWM Input’=On, ‘PWM Output Dither’=Off, ‘PWM Frequency/Damped’=High.
My PWM channel outputs are normal at 1090 when Disarmed.
I tried all other possible settings from MP and BLHeliSuite including OneShot, the only one avoiding this
issue is setting RC_SPEED from 490Hz to 50Hz.
It has always been working fine at 490Hz on different setups with previous versions, is there any recent change
in Copter 3.5 which would give an issue to the emlid RCIO driver ?
Hi George,
Now I do have rcio-dkms 0.6.6 and no more erratic outputs, thank you !
I will try to fly today with AC-3.5.0-rc2 and test the new AutoTune in PosHold.
BTW any explanation why I had these errors when I made ‘sudo apt-get update’ ?
