thank you very much for your reply! (and a quick one too)
about the pmw pins, i had an idea it might.. but as it says 15 pmw's and 2-13 is only 12 pins so i thought i had to be wrong with that assumption. any idea where the other 3 could located then? i only need one, and due to placing the excess to those ports are to say at the least trouble some.
my analog pins are all in use, and digital ports are accessible from pin 16 on, so i hope i can use another as such, this would make me really happy as it is basically the last issue i have before i can move on.
about SDA and SCl: indeed.. my bad, now i understand.. i was looking ad the pins SDA and SCl for the R3, which indeed is on a different spot.
much appreciated thanks
