I am using Pixhawk 4 . I am using MAVlink shell in Qgroundcontrol after connecting Pixhawk 4 to test various PWM’s channels .
I typed in the following
pwm arm
…
and then
pwm test -a -p 1500
-a = for all channels
-p = value of the PWM
it gave me an o/p (on mavlink shell)
[info] press ‘ctrl + c’ or ‘c’ to abort
I have connected the i/o pwm out from the Pixhawk 4 to this component provided by the pixhawk .
I connected the DSO probe to ‘S’ (signal of the o/p) & ’ - ’ (ground) and checked the pwm signal.
I found out that there was no output (only noise).
Would appreciate any input on this ? Am i doing anything wrong in the procedure .
@JulianOes I tried the pwm commands you told to perform on pixhawk 4. But still the pwm does not appear on I/O PWM .
For your information - Pixhawk firmware version - 1.8.2 (stable) with all sensors calibrated with flight modes.
led indications -
I/O led -
pwr - green led ON
B/E - off (amber led)
ACT - blue blinking
FMU led’s-
pwr - green ON
others off.
Also can you give me any info on what all these led means ?
I also have one more query . On QGC it shows all sensors calibrated (green signal on every where), but when i checked parameters tab on QGC for the same then i got no calibration data . I couldn’t find CAL_XSCALE_OFF,etc . What might be the reason for that ?
