Week 11: Networking and Communication

This week, I tried to replicate Neil's asynchronous network.

So, I built up one bridge board and two node boards as follows. And I was also able to successfully program it in avrdude.

The issue was I couldn't test it in term.py. When I tried to open term.py, it asks me to specify port and speed. I tried a few options (COM1, COM6) but it didn't work.

Overall it was a good exercise to build a set of boards. A few new tips that I got:

(1) Press up and down on PCB machine can cancel out all the on-going programming.
(2) Use sand paper can significantly clear up the traces after PCB machining.
(3) The tool that helps you to tightly hold the circuit board  can also help to tight up the 2X2 headers when you make those headers.
