Help Measuring RC pulsewidth

SteveW719

Would it be possible in Spin to use one counter to measure the pulse width of an RC servo signal and the other to output a proportional PWM signal with one cog? Or is this more a PASM type problem?
Would I use the edge detect mode some how to initiate timing on the rising edge? looking over app note 001 but it is not really jumping out at me how to accomplish this task.

Thanks in advance for any help.

Sure; set the counter in POS DETECT mode, wait for the signal to be low, clear PHSx, watch for the signal to go high, then, low, then grab a copy of PHSx. A little work, but not hard work.

Thanks Jon and Andy.

Jon looking at your article for N&V DMX LED where you use a similar method to measure break time I think. I will look closer at the code.
