The timing is off but I knew to expect that, but the SetDutyCycle(either) doesn't function correctly.

thanks,
Chad

Hi Chad,
The SetDutyCycle() parameter is limited to 8 bits, so best to use the SetDuty10Bit() for ARM
SetDuty10Bit() actually takes a 16 bit parameter
(The naming is historic, as 32 bit processors are more recent)
Using the numbers in your attached program I would expect the duty ratio to be 128/6400 and 512/6400
Is that not what you get?

Ok, I get it now. I was trying to use a 16 bit number (in the 10 bit). I thought it was expecting a 16 bit number whole not the #/6400.

If I use 3200/6400 I get the expected 50% duty.. My goal was to make a ~10khz base freq then change the duty to modulate a led...

My error thanks!
