FabLab Academy 2012
Manchester Lab
David Forgham-Bailey
This week we had to build a wired or wireless network with at least two
nodes.
The simplist wired asynchronous network requires a bridge board to
connect to a computer through an FTDI cable - and two node boards.
The boards are connected using a 4 strand ribbon cable - Rx/Tx/Vcc/Gnd
The boards are programmed using the FabISP - (each board is given its
own node identifier in the .c routine)
When connected to a computer using an FTDI cable - running
term.py - and pressing 0/1/2 - all boards flash to show they have
received a communication then the board with the same identifier will
flash again. (ie if key1 pressed - all boards flash then board 1
flashes a second time)
The boards were milled using the Roland Modella.
