PORTX.Y as function parameter ?

[Jacques Nilo]

Hello all !
I am trying to check the status of several push buttons with basically the same treatment. I initially tought I could do something along the following line:

;Chip Settings
#chip 16F690, 8
#config FOSC_INTOSC, WDTE_OFF

#define Red_button      porta.0         ;Set red pushbutton
#define White_button    porta.1         ;Set white pushbutton
;#define other buttons

Dir Red_button   In
Dir White_button In

Sub Test_button(Button)
  If Button On Then
;   Some treatment here
  End if
end sub

do
 Test_button(Red_button)
 Test_button(White_button)
; test other buttons
loop

But this does not work (compiles ok but get "Symbol does not exist" msg when assembling).
Any idea for a work around ?

Very easy to overlook. An equals sign in your if-then statement. You need to ensure you have a complete conditional test.

Sub Test_button(Button)
If Button = On Then
; Some treatment here
End if
end sub
