Hello Serial Bus - Using C

bus

The purpose of this hello world example is to network several boards together in the form of a serial bus. The bridge board is connected to a computer via a FTDI cable. The two node boards are connected to the bridge board.

To replicate this example:

  1. Download the Fab Academy board diagrams / pngs and code.
  2. For each node in your network, you will need to modify the modify the "hello.bus.45.c" code.
  3. You need to change the line: #define node_id '0' --> each node needs to have a different number (0, 1, 2, 3 - for each additional node you add.
  4. After flashing boards with 3 different node numbers:
  5. Open a Arduino IDE
  6. Open the serial monitor
  7. Enter number of note into serial monitor - press "enter"
  8. The node name (ex: node 1) should echo in on the serial monitor and the LED on the board that was flashed with the node id of 1 should flash.

Alternately- If you don't have / want to use the Arduino IDE,

  1. After flashing boards with 3 different node numbers:
  2. Download term.py(righ click save as)

  3. Run term.py

    In Ubuntu this is:

The node name (ex: node 1) should echo in on the serial monitor and the LED on the board that was flashed with the node id of 1 should flash.
