Loconet Shield

The Loconet Shield interface is a simple experimenter's interface to Digitrax's Loconet model railroad control bus. It is the same circuit as used on my [[LoconetBreadboard]], [[Turtle]] and [[Detector]] projects with the addition of a safety resistor protecting Q1 from the accidental application of 14V DCC signals to the Loconet Jack pins.

'''Loconet Breadboard Interface features'''
* 5v power input taken from breadboard
* A complete hardware interface to Digitrax's Loconet
* Two LocoNet interface connectors
* Optional LED "network activity" feedback
* RX and TX data streams for connection to appropriate processor input and output pins.

The schematic and PCB layout were created using the free tools provided by [http://www.cadsoft.de/ Eagle CAD]. Unlike ExpressPCB, you need to do [[BatchPCB-howto|a bit more work]] to get boards fabricated.

* [http://www.cadsoft.de/ Download Eagle CAD] (Windows, Mac and Linux)
* [http://www.spcoast.com/pub/CP/LoconetProtoboard-1.0.eagle.tar Download Loconet Protoboard 1.0 Eagle Schematic and PCB]

==Project Overview==

This project is actually quite simple; the design tools used are all free, you don't need to be an electronics expert to use them to order your own printed circuit boards; construction and assembly is easy - it takes about 15 minutes to assemble the board and maybe another 15 minutes to download the Arduino Loconet I/O demo sketch, wire your Arduino to this board and start hacking together your own loconet device:
* Ground goes to Ground, Vcc goes to a source of 5v power
* TX goes to D7 on your Arduino, and
* RX goes to pin D8

Without any Loconet connection, the LED will be on; with a connection, it blinks when packets are seen on the bus.

Download the [http://www.spcoast.com/pub/LoconetRxInterruptsSketch.zip Arduino Loconet demo sketch] into your Arduino Sketches directory, compile it, load it onto your Arduino, plug the board into your Loconet (the LED should go off) and away you go - your imagination is the limit!

See the [[:Category:Electronics]] Overview page for more information.
