I was wanting to play around with using this hardware to control a variable pitch multirotor design. So instead of plugging into ESC's I would use servo's for thrust control. But the issue is that most all quadcopter controllers use a 400Hz 1520uS centering signal. The better quality servos for FBL/tail helicopters use an advertised input of 333Hz max at 1520uS and then switch to 760Us centering for higher Hz rates.
Can the Ardupilot be told to put out a slower Hz rate easily? Something like 270Hz at 1520uS?
Yes, the rc_speed parameter defines how fast the Timer outputs PWM pulses. Value is in Hz.
Cool, thanks, this will be a big help.
