PIC12F675 - using an interrupt call

[vmatthews]

Was trying to use GPIO.2 Port as a interrupt change as listed in the Help's Interrupt listing.
Found no help in the 'Help' with GC for the 'GPIOchange' interrupt trapping.

Seems like I need something for the H2OLevel to be coupled with
the GPIOchange command.

NOTE: I am able to get EXTINT0 using AN2, but Still wanted to understand the GPIOChange command

Thanks, vic

;Chip Settings
#chip 12F675,4

#define H2oLevel an2
#define LEDStatus GPio.4
#define Horn GPIO.5

dir LEDStatus out
dir Horn out
''test LED and horn
for tempx=0 to 9
set horn on
set ledStatus on
wait 20 ms
set horn off
set ledStatus off
wait 50 ms
next

''' when resistance drops on AN0 do Int
    '''*** below is the line I would like to understand..
'On Interrupt gpiochange call HornAlert 
    ''  the line belows is what is working..
    On Interrupt ExtInt0 call HornAlert
IntOn
Do 
Wait 1 s 
set  LEDStatus on
Wait 1 s 
set  LEDStatus off
Loop

Sub HornAlert 
    for tempx=0 to 9
set Horn on
wait 250 ms
set horn off
wait 250 ms
next
End Sub

Did you ever resolve this?

I have not figured out how the GPIOChange functions.

[Anobium]

Can you describe what you are trying to achieve? I am sure we can then help you.

Looks like the GPIO2 (extINT pin) is not set to digital input. If button is grounding the pin, then it wouldn't hurt to turn on the weak pullup for that pin. So,

Dir GPIO.2 In
Set WPU2 ON

Edit: Same thing for On Interrupt GPIOChange..., need Dir GPIOX In.
