What a stragne treat nowhere does it say adam is using d-shot, and if he was non of these problems would be possible…
Adam, i think you’re right about the “beta running ChibiOS”. What “MOT_PWM_TYPE” do you use?
I don’t calibrate my esc’s. I know there is a small difference possible per esc because the analogue way the signal is measured, but i don’t care… (i use "MOT_PWM_TYPE: 2 right now)
My suggestion is: buy an arduino nano, hook it up to BL-Heli suite and turn it into a programmer (4-way-interface Multi). Then connect all esc’s to it (signal and a common ground).
(Or you can use fw3.6 with chibios)
In BL-Heli suite I put “PPM Min throttle” to 1040 and “Max” to 2000.
in arducopter:
MOT_PWM_MAX 2000 PWM
MOT_PWM_MIN 1000 PWM
MOT_PWM_TYPE 2
MOT_SAFE_DISARM 0
MOT_SPIN_ARM 0.075
MOT_SPIN_MAX 1
MOT_SPIN_MIN 0.10
If you’re using Dshot calibration is not needed! And Mot_pwm min and max are meaningless.
