18F2431 Pwm
PostPosted: Tue May 22, 2007 1:45 pm     Reply with quote
On the datasheet of the 18F2331/ 18F2431 i can see PWM0 up to PWM5.
But i cannot use: set_pwm3_duty() More than 2 is not possible, the device has 6 pwm outputs or do i misunderstand something?

Mark.

Look at the functions 'set_power_pwmX_duty'.
The power PWM generators, have different setup requirements, from the normal PWM generators, and use different setup commands. The chip has tw normal CCP/PWM modules, and then on top of this, four power PWM generators (only 3 on the 2x31 chips).
You don't say what compiler version?. On the current versions, the power functions work, but on some older versions, there were problems with these.

Best Wishes
