DT INTs which int to use??

[Heckler]

So, for clarification, here is what I have that is working...

IOCB=%11110000    'enable INT on change RB 7,6,5,4

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

Note that I changed the individual ...

'IOCB.7=1    'enable INT on change RB7
'IOCB.6=1    'enable INT on change RB6
'IOCB.5=1    'enable INT on change RB5 rotary push button

Into one statement...

IOCB=%11110000    'enable INT on change RB 7,6,5,4

(and added the additional bit that enables IOC on B.4)

But I still wonder which part of my code is actually enabling the INT on change. As I look over at darrel's web page where he gives examples I do not see anywhere that he has to manipulate the registers to enable the INT's.

So I am back to thinking that it is really my code

IOCB=%11110000

that is making the INT's work and part of Darrel's code that tells the PIC where to jump to on INT. "Binthndler"

still confused

To know which Int to use, you need to be a bit of a sleuth, the same thread...

I think you need to open dts_int-14.bas, do a search within for RABC, you should see these entries...

  #define RAC_INT      INTCON,RAIF,  INTCON,RAIE   ;-- RA Port Change      *
  #define RBC_INT      INTCON,RBIF,  INTCON,RBIE  ;-- RB Port Change
  #define RABC_INT     INTCON,RABIF, INTCON,RABIE  ;-- RAB Port Change

....see which one of those bolded registers a 16f690 actually has & then use the associated DTS Int. (eg search the data sheet for RAIF...nothing, RBIF...nothing, RABIE ...bingo ...so use the RABC_INT)
