Stopping a PWM?

[Guest]

Hi

Is this the same as the CCP1 pin will be "L"?
set_pwm1_duty(0);

Ask because it dont?

You need:

set_pwm1_duty(0L);

Note the 'L'.
The PWM, has a ten bit resolution. The 'set_pwm_duty' function, needs to receive a 'long' value, to access all ten bits. If you only give it a 'short' value (the '0' in your original command), then only the upper 8bits of the PWM, will be accessed. _If_ the two low bits have been set to a non zero number (as will have happened if you have output any 'long' value to the PWM), then these will still be set, and you will get a tiny pulse of 1,2, or 3 PWM clocks.

Best Wishes

And 2 more cents - if you are using variables to do your PWM work - just remember to use a LONG for calling setPWM
