Instant interrupt problem (very strange)

[yusoweird]

I wrote a program that uses Darrel's instant interrupt. It was work perfectly. But, I accidently overwritted it. =( I am so dumb. But anyway, this is the problem I'm having since I rewrote the program...

 
define OSC 20    
define LCD_EREG PORTE		
define LCD_EBIT 0			
define LCD_DREG PORTD       
define LCD_DBIT 4          
define LCD_LINES 4   

define ADC_BITS 8      
define ADC_CLOCK	3     		
define ADC_SAMPLEUS 100
define BUTTON_PAUSE 300         

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    RBC_INT,  _ToggleLED2,   PBP,  yes
        INT_Handler    INT_INT,  _ToggleLED1,   PBP,  yes
    endm
    INT_CREATE               ; Creates the interrupt processor
ENDASM

pause 1000
TRISB = %11100001                                                    
@    INT_ENABLE   RBC_INT
@    INT_ENABLE   INT_INT     ; enable external (INT) interrupts


    Lcdout $FE, 1,   "HELLOW WORLD"
    LCDOUT $FE, $C0

Main:

  PAUSE 100
  
GOTO Main

'---[INT - interrupt handler]---------------------------------------------------

ToggleLED2:
lcdout "no"
pause 100
@ INT_RETURN

ToggleLED1:
lcdout "hi"
pause 100
@ INT_RETURN

The program compiles fine, but when ever I turn on my circuit, RBC_INT is constantly interrupting. All i see is "nonononono..." on my lcd. I cant figure out why it is doing this since I did not change any hardware. Then, I reloaded my old hex file of my previous working program and RBC_INT works fine and does not constantly interrupt. I have no idea what is causing this. Please help me =(

I forgot to say that portb0, portb5-7 are all pulled down and connected to a momentary buttons to 5V.

Hi yusoweird,

You need to read PORTB in the interrupt routine to end the mismatch.

AHH! Thanks Darrel!!!! =)
