@dagar much thx I see it´s documented inside the code … will try it. An issue is already in process #8312 the Z mixer of ch 4 can be changed in 1.7 without affecting the other mixers while in 1.6 all following mixers were shifted by one. The PWM limit of 2150us can be changed in drv_pwm_output.h
device: /dev/pwm_output0
channel 1: 900 us (alternative rate: 400 Hz failsafe: 900, min: 1080 us, max: 1943 us)
channel 2: 900 us (alternative rate: 400 Hz failsafe: 900, min: 1080 us, max: 1943 us)
channel 3: 900 us (alternative rate: 400 Hz failsafe: 900, min: 1080 us, max: 1943 us)
channel 4: 1500 us (alternative rate: 400 Hz failsafe: 2000, min: 995 us, max: 2005 us)
channel 5: 2449 us (default rate: 50 Hz failsafe: 1985, min: 701 us, max: 2450 us)
channel 6: 701 us (default rate: 50 Hz failsafe: 1030, min: 701 us, max: 2450 us)
channel 7: 1521 us (default rate: 50 Hz failsafe: 1522, min: 722 us, max: 2322 us)
channel 8: 1522 us (default rate: 50 Hz failsafe: 1522, min: 722 us, max: 2322 us)
