I had a quick question after running some initial test.
It looks like the Navio2 PWM output is limited at 400Hz regardless of setting the ESC frequency above 400Hz.
As you can see below, I have captured the PWM (for a hexa) at several different frequencies and they seem to match pretty well from 50Hz up to 400Hz by adjusting the APM RC-SPEED setting
PWM Output 50Hz with RC-SPEED = 50Hz
PWM Output 250Hz with RC-SPEED = 250Hz
PWM Output 400Hz with RC-SPEED @400Hz
PWM Output 400Hz with RC-SPEED = 490Hz
As you can see from the above captures, the output of the PWM is limited at 400Hz output regardless of the RC-Freq output > 400Hz.
Is there a way to increase the limit? When will the PWM examples be released and will the ARM ST32F code be released into the public domain?
