Should your efforts not be directed towards a "clip on circuit" that could be connected to the system to achieve In System Programming? In the schematic of Charles the header JP1 allows this "clip on" to the system. Only thing needed is some jumpers, which disconnect the according micro's pins from rest circuitry and connect them to the header's lines. But this is very easy. I would still recommend to add 4k7 pull-ups to all the involved port pins, especially at Reset pin. Kai |
