if I have to write PWM values to servo, is there a uORB topic I can use? I see a topic actuator_outputs
, but I am under the impression that it just contains the current PWM values (maybe I am wrong and this is the uORB topic I should use). The pwm
system command uses ioctl
. So is ioctl
the only way to write the PWM values to servo?
If ioctl
is indeed the only way to write pwm values to servo, I am curious how does servo reads the values? Which modules reads the pwm values and passes to the driver?
