I can change the frequency by the qshell command

qshell pwm -a -r <rate>

another, I would like to know how to change the PWM duty cycle.

Thanks

Hi
I use voxl2 board to connect voxl2 io expander board at J19.
I would like to control PWM signal by "qshell pwm" command first. How to do it ?

I use below command to do it, but there is no any PWM signal change.

qshell px4io detect
After this command, PWM output 50Hz signal
qshell px4io start
qshell mixer load /dev/px4io quad_x_io.main.mix
qshell pwm rate -c 1234 -r 400
I try the -c <pwm_ouput>, there is no any PWM signal change.

Hi
I bought voxl2 I/O expander board with MDK-M0065-02.
Does it flash any image in voxl2 I/O expander board ?
If yes, how to read version from voxl2 I/O expander board ?

Another, where to download modalai_voxl2_io_bl.bin and modalai_voxl2_io.bin? I would like to connect it with voxl2 board for our development.

Thank you
