Hi Peter,

I loaded up the example into MPLAB-X, compiled and ran the simulator=20
since I don't have a part.  The example code runs fine. The output will=20
never blink, but will have 32 distinct DutyCycle levels.  If it is=20
working, you might see the LED intensity vary slightly.  A scope on the=20
output pin would be better for checking the duty cycle changes.

Comparing the hex file I generated vs. the included one -- they are=20
different.  But I'm using the free bloatware version of xc and I'm sure=20
the Microchip employees are using the 'omniscient' version.  Can you=20
compile the example and get that to run?

And as far as trusting example code, I try to live by 'trust but verify'.

Bill
