ECCP module problem

[Darrel Taylor]

why is this code not working on 18F1320.any ideas!!!!

P1A  var PORTB.3    ' ECCP pin defines . 
P1B  var PORTB.2    
P1C  var PORTB.6    
P1D  var PORTB.7    
TMR2IF  var PIR1.1 ' TMR2 interrupt flag



    P1A=1        'Tristate
    P1B=1        ' Tristate
    P1C=1        ' Tristate
    P1D=1        'Tristate

Those are changing the PORT value, not it's input/output state.

Try TRISB.x for P1A-D.

Hi!
still not working!!!

[Darrel Taylor]

Is there more to your program?

If not, then the FORWARD routine is RETURNing but it wasn't called with a GOSUB.

Also,

;------------------------
CCP1CON.4 = DUTY.0 ; here we stat loading the CCPR1
CCP1CON.5 = DUTY.1 ; with the value of DUTY Cycle parameter
CCPR1L = DUTY >> 2 ;
;-----------------------
CCP1CON = %01001100 ; set CCP1CON to full bridge , high output, Forward

By setting CCP1CON after seting to 2 LSB's of the dutycycle, it overwrites those bits and you lose resolution.
