irmc - Internet Relay Morse Code
|
||||
================================
|
||||
IRMC stands for Internet Relay Morse Code and is an implementation of [MOIP](https://github.com/8cH9azbsFifZ/moip).
|
||||
It implements the [CWCom protocol](http://kob.sdf.org/morsekob/docs/cwcom.pdf)
|
||||
as adopted by [MorseKOB](http://kob.sdf.org/morsekob/docs/history.pdf).
|
||||
IRMC stands for Internet Relay Morse Code and is an implementation of [MOIP](http://8ch9azbsfifz.github.io/moip/).
|
||||
|
||||
# How to build?
|
||||
## Install dependency: morse keyer library
|
||||
```
|
||||
wget https://github.com/8cH9azbsFifZ/morse/archive/v0.1.tar.gz
|
||||
tar xzf v0.1.tar.gz
|
||||
cd morse-0.1
|
||||
libtoolize
|
||||
./autogen.sh
|
||||
./configure --with-portaudio
|
||||
# Building
|
||||
## On Linux
|
||||
sudo apt-get install -y alsa-oss oss-compat build-essential autoconf libao-dev libtool libportaudio-dev portaudio19-dev
|
||||
make
|
||||
|
||||
### On Raspi (GPIO Interface)
|
||||
Follow: http://wiringpi.com/download-and-install/
|
||||
make raspi
|
||||
|
||||
|
||||
## On OSX
|
||||
brew install portaudio
|
||||
make
|
||||
sudo make install
|
||||
```
|
||||
|
||||
## Debian (Wheezy)
|
||||
Some dependencies have to be installed:
|
||||
```
|
||||
apt-get install -y alsa-oss oss-compat build-essential autoconf libao-dev libtool
|
||||
```
|
||||
Afterwards compilation with `make` should work. If something went wrong, you may have
|
||||
to adjust your `LD_LIBRARY_PATH`. Alternatively try:
|
||||
```
|
||||
LD_LIBRARY_PATH=/usr/local/lib ./irmc mtc-kob.dyndns.org 7890 33 123
|
||||
```
|
||||
|
||||
## OSX (Yosemite)
|
||||
Compilation with make :)
|
||||
|
||||
For the USB serial devices you need a PL2303 driver
|
||||
(i.e. [PL2303_Serial-USB_on_OSX_Lion.pkg](http://changux.co/osx-installer-to-pl2303-serial-usb-on-osx-lio/)).
|
||||
|
||||
