irmc-avr

IRMC stands for Internet Relay Morse Code. This is an implementation of a MOIP client.

Prototype

#Building Build the firmware under OSX: port install avr-binutils avr-libc avr-gcc avrdude make burn

#Testing Observe the "DG6FL/AVR" on http://mtc-kob.dyndns.org on channel 33.

Testing with MorseKOB 3.0 (Java)

This software will run on Linux, Windows and OSX. With the RXTX software for Java (i.e. librxtxSerial.jnilib on OSX) it is even possible to connect to external hardware. NB: before you transmit make sure you uncheck the "circuit closer".

Hardware

I use an duemilanove with a W5100 Ethernet Shield

The wiring is as follows: (see pin mapping)

Pin Arduino Name  Function
PD6 Speaker
 PC5  analog Input 5 Key (5V!)
PD7   Connect LED
PD4 Data LED

Code Quality

This is experimental code. The latest version working without too much tweaking is v0.2
