Just thought I would let everyone know, that Roman Blacks "picsound" page has been updated. There is now a windows program for converting wav files to the bit stream.
For those who haven't seen this page before, this guy came up with a way of generating sound using a PIC microcontroller, and it uses only 1 or 2 of the pins. Its really ingenious!
