Sorry, Rob, little mistake:
You need to check the PORTC register. The LATC register contains the output
pattern, not the input state of the port pins.
Otherwise a good idea :-)

Hi Filipe,
I never tried this but here is a thought.
The pin on a specific port can be found in the LATx register, example below for
portc this is LATC.
You find this in your device file for e.g. pin_C2var volatile bit LATC_LATC2
at LATC : 2var volatile bit pin_C2 at
PORTC : 2
So if you have for example your buttons on port C you could pass a 'mask' as
parameter to the procedure. Example below (not compiled):
function pin_active(byte in pin_mask) return bit return (LATC & pin_mask)end
function
So if you want to if test pin C1 is active (HIGH) or pin C7 is active (HIGH)
you do:
if pin_active(0b0000_0010) then -- Do something for bin C1 end if
if pin_active(0b1000_0000) then -- Do something for pin C7 end if
Kind regards,
Rob
