Programming the board
By the Neil's file hello.bus.45.make I am going to programm the bridge board
Programming the bridge board make -f hello.bus.45.make program-usbtiny or make -f hello.bus.45.make program-avrisp2
Once the bridge board is programmed, I change the .c file for a subsequent node board that have a different ids.
Programming the node board hange line 41 from node_id '0' to node_id '1':
programming process again, plugging the programmer into the node board
Networking
Using your FTDI cable, connect your bridge board to your computer's USB. Also connect the node board to the bridge board via a 4-pin ribbon cable.
Test Network select ATTiny 45 selected and the USB/FTDI port selected
