In the Makefile I changed
avrdude -c ? to remind myself the name of the programmer is
avrdude -p t45 -P usb -c atmelice_isp -U flash:w:$(PROJECT).c.hex
Then I ran
make -f hello.bus.45.make which indeed generated the text files, and then
make -f hello.bus.45.make program-atmelice_isp to program the board. Seems to have worked without issue!
Worked on the second, but the third I had a t85 rather than a t45. Ooops! For kicks switched t45 to t85 in the Makefile, and that worked! All the nodes light up when a key is pressed. Had the network powered through the FTDI cable.
Oops I gave them all the same node_id of '0'. So then copied the
The network works! It will be fun to play with the protocol or perhaps to add a sensor to query different boards upon pressing a button.
