DT interrupt problem

[eggman]

Hello everyone, I'm having trouble making my program work. I'm using DT interrupts to measure the duration of a servo pulse using CCP interrupts.
The interrupt routine works as expected but it doesn't return to the Main program, I'm missing something. Any input is appreciated.
Code:

#config
 __config _INTRC_OSC_NOCLKOUT & _WDT_OFF & _MCLRE_OFF & _CP_OFF   
#endconfig
define OSC 8
Include "modedefs.bas"
INCLUDE "DT_INTS-14.bas"     ; Base Interrupt System
INCLUDE "ReEnterPBP.bas"     ; Include if using PBP interrupts

ASM
INT_LIST  macro    ; IntSource,        Label,  Type, ResetFlag?
        INT_Handler    CCP1_INT,  _pulsedata,   PBP,  yes
    endm
    INT_CREATE               ; Creates the interrupt processor
ENDASM

@   INT_ENABLE   INT_INT     ; enable external (INT) interrupts

GPIO     = 000000
TRISIO   = 000101           
ANSEL    = 000000
CMCON0   = 000111       
OSCCON   = 110000  '8MHZ
PIE1     = 100000
INTCON   = 010000
T1CON    = 000001  'no prescaler
CCP1CON  = 000101  'rising edge CCP
led      var GPIO.5
wsave    VAR BYTE    $20     SYSTEM      ' location for W if in bank0
pulse    var word     'received pulse width

clear

Main:
     pause 100
     toggle led
GOTO Main

'---[INT - interrupt handler]---------------------------------------------------
pulsedata:
     if CCP1CON.0 = 0 then
         pulse.lowbyte = TMR1L
         pulse.highbyte = TMR1H
        ' serout 4,N9600,[#pulse,13]    'for testing
         CCP1CON.0 = 1         'rising edge CCP         
     else
         TMR1L = 0
         TMR1H = 0
         CCP1CON.0 = 0         'falling edge
     endif         
@ INT_RETURN


end

I'm no expert, but you've created a

CCP1_INT interrupt, then done this...

@   INT_ENABLE  INT_INT       ; enable external (INT) interrupts

to my way of thinking (possibly wrong!) it should be this...

@   INT_ENABLE  CCP1_INT       ; enable CCP1 interrupt

(that's assuming you want to interrupt on CCP1 & not the INT pin?)

Thanks for the suggestion, but my interrupt routine works okay. I tried it but it makes no difference. Somehow it will not run the main program, it will handle all the interrupts though.

What if you change the pause from 100 to 15?

[Darrel Taylor]

Although the forum has messed up your binary numbers (as usual), you can still see problems.

You have enabled INTE in the INTCON register, but there is no handler for INT_INT.

You have enabled RCIE in the PIE1 register, but there is no handler for RX_INT.

It never returns to you program, because the interrupts are never handled.

Thank you Darrel for pointing me in the right direction, it works fine now!
