You low level programmer you ;-) In Arduino-ese, you don't normally play directly with DDRB and PORTB, because various bits are automagically connected to Sun, 06 Jan 2013 19:18:47 GMT John McKown http://groups.yahoo.com/group/chordite/message/620 http://groups.yahoo.com/group/chordite/message/620 Yes, what Steve said, I think. The following may be off target as far as helping goes but won't take me long to write so what the hell.

If you use digital pins 2-7 and 8-9, you can use direct port manipulation, like this switchAll = (PIND & 3) | (PINB & 3); //this has the advantage of Sat, 05 Jan 2013 23:33:15 GMT L.

I think the existing teensy code (mine+Atmels) is pretty far from what you need because the RN-42 takes Fri, 04 Jan 2013 15:05:15 GMT John McKown http://groups.yahoo.com/group/chordite/message/615 http://groups.yahoo.com/group/chordite/message/615 Here is one other thought on getting a unit to fit well with a solid grip. What I call the bottom pad is, in my illustrated instructions, a piece of fake cork Fri, 04 Jan 2013 01:19:53 GMT L. Eli. http://groups.yahoo.com/group/chordite/message/614 http://groups.yahoo.com/group/chordite/message/614 thats what i am using but im not a programmer and finding it a little hard figuring out how to make the code right. i have been trying to port the teensy code Fri, 28 Dec 2012 21:30:45 GMT John McKown http://groups.yahoo.com/group/chordite/message/613 http://groups.yahoo.com/group/chordite/message/613 To further illustrate braces I put some more pictures of one of the somewhat mangy units I constantly use into the Photos section of the Yahoo group in the Tue, 25 Dec 2012 11:06:49 GMT Steve T http://groups.yahoo.com/group/chordite/message/612 http://groups.yahoo.com/group/chordite/message/612 Has anyone mentioned the new Arduino Leonardo, which supports USB keyboard profiles "out of the box", it makes writing a keyboard very, very easy.
