Kind of late responding, but the forum just sent out (in Dec) an email notice there were 4 post to the thread (last in Aug ?). Procrastinator club anyone ?
Anyway, it's not ic specific since the original demo program that came with the board can be reloaded (external device programmer) into the exact same ic and it will run from power up. But the PBP compiled program does not start to execute until the reset button is manually pressed.
I don't know what the real cause was, eventually I chucked the board, PBP, and Hellebuyck's book in a drawer, and things got better.
Cheers, Bobby
PS. Royalty checks only prove people bought it, not that they found it useful.
