Hpwm @ Pic16f777

[fuhr3r]

HPWM 2 and 3 not working. I`m using the same frequency for 1, 2 and 3.

Can someone helpme?

is it me or you forget to post the code?

BTW..

1. look respective timer in use for each PWM module
2. Look PBP manual in the HPWM section DEFINE....
3. look for config fuse
4. Datasheet
5. goto step 1

fuhr3r,

since you are new to the forum you should have a look at THIS

Hi, the code is very big, almost 8k and commented in portugueese

This PIC have 2 pins for CCP2, selected with the fuses, so does it need the DEFINES?

[fuhr3r]

DEFINE CCP2_REG PORTB ' Hpwm 2 pin port
DEFINE CCP2_BIT 3 ' Hpwm 2 pin bit

Now HPWM 2 works, but HPWM3 still not working.

I tryed DEFINE CCP3_REG PORTB and CCP2_BIT 5, but did not work. (only CCP has 2 choices of pins).

Tomorrow i will try simulate with MPLAB or put a LCD showing CCP3CON.

Nobody ever used 3 HPWMs?

"Nope. The HPWM command only supports 2 channels. CCP1 & CCP2. You
would need to modify the 16F library to support CCP3. It's much easier to
just configure hardware PWM manually."

Problem solved....
