Hi. I am currently putting together a project to design a flexible facilitated communication device to help disabled people communicated - those suffering from autism, for example. This will end up an open source design and software. Anyway, Ive hit a snag and hope a few people will take a look for me.... take a look at http://members.xoom.com/tonynich/problem/index.html I have a deep, deep suspicion it is something silly. By the way, I knew nothing about PIC's or microcontrollers when I started this, 6 months ago. It is only thanks to this list and certain individuals who I met via the net that its got this far. Many thanks.
