hpwm more than 2 ch possible in pbp?????????

Help us a litle bit Pic model?

How bad/good it is if in the INT routine you test the PORTB and if it's just related to the HPWM, it goes out of there ?

Sorry Im using the same pic as Bruce example: 16F767

but Im having more basic problems, when I wasnt able to run the program as desired I started to remove parts of it, and now I see it does not work at all, so I may be missing some register configuration.

Here is the header of my program:

@ device pic16F767, wdt_on, intrc_osc_noclkout, mclr_off, protect_off


trisb   =%11000000
trisa   =%00000001
cmcon   =%00000111  'Comparators Off
intcon  =%10001000  'interrupts enable    

; Set CCP modules to PWM mode
CCP1CON = %00001100 ' Mode select = PWM
CCP2CON = %00001100 ' Mode select = PWM
CCP3CON = %00001100 ' Mode select = PWM

PR2 = $20    ; Set period 

pie2.1=0    ;disable interrupts on CCP3 (I think this should work)

; Set TMR2 up for 1:1 prescale & turn it on
T2CON = %00000100 ' TMR2 ON 1:1 prescale

porta=0:portb=0:portc=0

pause 100


high porta.1
pause 200
low porta.1
pause 200
high porta.1
pause 200
low porta.1

end

As you can see very basic, and I dont even started with the pwm/interrupts stuff.

I program the pic via ICSP and power it, it seems to run at turtle speed , the 200ms pause takes 28seconds...


What I am missing? Thanks

What is about a DEFINE OSC ?
At what speed does the PIC work ?
What speed did you tell the PBP-Compiler ?

;-)

Oh I didnt post it in my previous post sorry, there is a define osc 4 below the @device statement

but it still goes slow...

any idea? Thanks

I could use some help Thanks in Advance

This seems to be a very popular comment. Bruce mentioned that you could modify the 16F library to accomodate for the 3rd HPWM channel. Could any of the advanced members take on this project and post the library? Seems that it would solve many repeat posts for the same problem.
