DT interrupts - High to Low

[mpardinho]

the code works, but _B0 is started then PORTB.2 Low to High,
i need High to Low


i tryed
DEFINE LVDINT = PORTB.2
and
DEFINE HLVDINT = PORTB.2

but not work

Button var PORTB.2

ASM
INT_LIST  macro   ;IntSource,   Label,         Type, ResetFlag?
   INT_Handler    INT2_INT,     _B2,     Asm,  Yes   
   INT_Handler    RX_INT,       _Rx,    Asm,  Yes
   Endm

   INT_CREATE
   INT_ENABLE INT2_INT
   INT_ENABLE RX_INT
ENDASM

.....

B2:
   IF Button    = 0 then
      hserout["0"]
   else
      hserout["1"]
   endif
Fim:   
@ INT_RETURN


Rx:
   hserout["Rx"]
Fim:   
@ INT_RETURN

Hi,
I'm not sure I understand what you mean, you mean you want the INT2 interrupt to trig on the falling edge of PortB.2?

Anyway, one problem might be that you declare the ISRs as ASM but then you write them in BASIC. It will also be easier for people to help you if you tell us which PIC you're using.

/Henrik.

many thanks.....


i used
INTCON2.4 = 0 ' PORTB.2 - Lo to Hi
and works 100%
