16 bit PWM using CCP1

[richard]

I didn't pickup what ver of pbp talat was using , and I'm not sure if the chk?rp macro exists in early versions


but try

Asm
PWM_INT
CHK?RP   CCP1CON
movlw 9 ; compare mode
clrf CCP1CON ; clear reg
movwf CCP1CON ; Set reg
CHK?RP  PWM_VAL
movf PWM_VAL+1,W ; hb
CHK?RP   CCPRIL
movwf CCPR1H ; put
CHK?RP  PWM_VAL
movf PWM_VAL,W ; lb
CHK?RP   CCPRIL
movwf CCPR1L ; put
banksel 0
bsf INTCON,7 ;GIE = 1
bsf INTCON,6 ;PEIE = 1 Enable peripheral interrupts
bsf PIE1,0 ; TMR1IE= 1 Enable TMR1
bcf PIR1,0 ; TMR1IF = 0 Clear Timer1 Int Flag

RETFIE ; Return from Interrupt
EndAsm

if that fails try

banksel CCP1CON OR WHATERVER SFR

OR
read data sheet and find what bank each sfr is in


with all that bank switching the effort may be pointless

post 35 is wrong pie1 is not in bank0 either

Asm
PWM_INT
CHK?RP   CCP1CON
movlw 9 ; compare mode
clrf CCP1CON ; clear reg
movwf CCP1CON ; Set reg
CHK?RP  PWM_VAL
movf PWM_VAL+1,W ; hb
CHK?RP   CCPRIL
movwf CCPR1H ; put
CHK?RP  PWM_VAL
movf PWM_VAL,W ; lb
CHK?RP   CCPRIL
movwf CCPR1L ; put
banksel 0
bsf INTCON,7 ;GIE = 1
bsf INTCON,6 ;PEIE = 1 Enable peripheral interrupts
CHK?RP   PIE1
bsf PIE1,0 ; TMR1IE= 1 Enable TMR1
BANKSEL 0
bcf PIR1,0 ; TMR1IF = 0 Clear Timer1 Int Flag

RETFIE ; Return from Interrupt
EndAsm

it just gets worse

Richard and EarlyBird,
Thank you very much for your generosity and support.
I'm using version 3.0.1.4.
