Programming boards

1. Flash all the boards with the hello bus code.

• Flashing the bridge:
The bridge is node 0:
#define node_id '0'

• Flashing nodes. They have to be powered from the bridge board by connecting boards like this:
  
• Once every board is programmed, it works like in Anna's tutorial.

2. Editing the hello bus code.
I test this:

• Editing the delay on the third node:
  #define led_delay() _delay_ms(500) // LED flash delay


• Editing the message is going to appear at the arduino IDE.
  const static char message[] PROGMEM = "hola soy el nodo 3";

I have one ".c" and ".make" file for each node. To be changed at the ".c" file for each node:

• hello.bus.45_1.c #define node_id '1'


• hello.bus.45_2.c #define node_id '2'


• hello.bus.45_3.c #define node_id '3'

I copy the .make file we download here and change its name to prepare each .make file for the nodes. To be changed at the .make file for each node:

• hello.bus.45_1.make

"PROJECT=hello.bus.45 " to "PROJECT=hello.bus.45.1 "
• hello.bus.45_3.make

"PROJECT=hello.bus.45 " to "PROJECT=hello.bus.45.3 "
• hello.bus.45_2.make

"PROJECT=hello.bus.45 " to "PROJECT=hello.bus.45.2 "

Once every board is programmed it works like this:
