Instant Interrupts - Revisited

[Dave]

Howard, you must be setting the reset flag to TRUE by entering YES in the interrupt declaration ResetFlag field like this:


ASM
INT_LIST macro ;IntSource Label Type ResetFlag
INT_Handler IC3DRIF_INT, _InputSignal, ASM, yes
endm
INT_CREATE
ENDASM

Hello

Where can I find the homepage that were on these two links?
And where do I download the latest DT_INTS?

DT_INTS-14 (12F-16F)

DT_INTS-18 (18F)

I'm working on a project using 18LF13K22. I need to use RAB Change Interrupt with DT Ints18. I made changes on DT_INTS-18.bas below but i couldn't succeed. Any suggestion?

#define RABC_INT  INTCON, RABIF   ;-- RAB Port Change

.........

ifdef RABIF
      INT_Source  INTCON,RABIF, INTCON, RABIE,INTCON2,RABIP
  endif

Thanks..

I had to do the same thing with the PIC18F14K50.
Our entries look similar except your label is RABC_INT.

#define RAB_INT   INTCON, RABIF   ;-- RAB Port Change, Added 3/15/14 for PIC18F14K50

and

  ifdef RABIF    ;----{ RAB Port Change Interrupt }-----------[INTCON, RABIF]--- (Added 3/15/14 for PIC18F14K50
      INT_Source  INTCON,RABIF, INTCON,RABIE, INTCON2,RABIP 
  endif

Could it be you're not enabling it with:

INT_ENABLE  RABC_INT   ; Enable IOC

[LinkMTech]

Edit: ooops, forgot the "@".

@ INT_ENABLE  RABC_INT   ; Enable IOC

Thanks for your reply. I tried to work it with ISIS. It may cause for it. I'm waiting for chips. I will try it again.

The chips have arrived. I tried RAB change interrupt on a demo board. The situation is the same with isis. This is my test code below.

    INCLUDE "DT_INTS-18.bas"     ' Base Interrupt System
    INCLUDE "ReEnterPBP-18.bas"     ' Include if using PBP interrupts
    
    ........

    OSCCON  = %00110100
    OSCCON2 = 0
    OSCTUNE = %10000000
    
    TRISA   = %11101111
    TRISB   = %11111111
    TRISC   = %00000000

    ANSEL   = 0
    ANSELH  = 0
    
    INTCON2.7   = 0
    WPUA        = %00101111
    WPUB        = %11110000
    IOCA        = %00000111
    IOCB        = %01010000

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

    MAIN:

   
    ......
GOTO MAIN


     RABC : 
    
    COUNTER = COUNTER + 1
