Our assignment was to build a network. We had four boards to build. Board One was a bus for a FTDI to connect to the computer. Board Two, Three, and Four were Nodes and we used a "C program to assign them addresses.

With Mercedes and Dean's help one change helped to run all four of the boards. They used 'hello.bus.45.c with changes in two places to get the LED to blink when a specific computer key was pressed.

Change: Line 41 -take defined 'node_id' is assigned 0 for the bus, and the node boards are 1, 2, 3. Line 217 comment out the flash() function.

If you do not do this the LED lit up when any key was hit. By commenting it out the LED will light only when the correct computer key is pressed.

Mercedes and Dean figured this out quickly. It took me much longer. They were working on their radio board while I will still trying to figure this out.

Update:

I managed to get my boards programmed. I also managed to short them out later on. I have not had time to test them and trace down what I did wrong yet. I worked on a way to use this project to get the star on my Theater to blink in a pattern. Dean and I worked together on this. See my Final Project Page for the results.
