Tried a couple of times programming the boards with both the numeric (0, 1, 2) and alphabetical (M, I, T) IDs. However, for some reasons, only one node was able to talk back to the computer.
Matt Edwards suggested that this might have worked properly if I play around setting up the clock speed. No idea, and I knew that it was suppose to work properly, like Daniela's.
This week has been particularly rough for me, but, with the awesome Cagri Zaman, I spent the rest of the time making a bus connections by combining this week's Bus Bridge and hello.boards series as a quick test for my Final Project and the Machine Design group project.
