Not dead yet ! My GP2D02, when diode is correctly oriented, is still working
!...
But now I can't figure out how to pass pins to function. I've read things on
jallist, like
procedure bla(volatile bit out mypin) is
...
but I get a "parameter 1 type mismatch" error.
My procedure needs two pins as parameters. One will be written, the other
will be read. I've also tried this, no success... :
function gp2d02_read_pins(bit out pin1, bit out pin2) return byte is
-- the logic is like this
pin1 = low
pin1 = high
if pin2 == high then
-- do something
end if
end function
var volatile bit gp2d02_vin is pin_a4
var voltatile bit gp2d02_vout is pin_a6
var byte what
what = gp2d02_read_pins(gp2d02_vin, gp2d02_vout)
-- same with gp2d02_read_pins(pin_a4,pin_a6)
And I also tried this (no success too):
function gp2d02_read_pins(bit in out pin1, bit in out pin2) return byte is
...
end function
Any hints ?
Thanks
