CmdMessenger2 | Serial messaging system

Pretty much everything is explained within the example sketch file. Open CmdMessengerExample.pde in Arduino IDE and upload it to your microcontroller device. Check the baud rate is OK for your model. Try it out by typing commands into the Arduino Serial Monitor. Once its been established what is happening on the Arduino side by following the interactive example, the next step is to work on with the program running on the other side of the serial interface which will be communicating with the Arduino. There are a wide variety of platforms and programming languages which can be used. C, Python, Ruby, Linux, Windows, and other embedded devices. The possibilities are endless. A principal benefit of CmdMessenger is that the format of messages are both flexible and simple enough to be programmed in nearly any suitable language or programming environment that supports a serial (comm port) interface. The following C program arduino-serial is recommended for this task. It can be modified to suit your needs, or compiled "as-is" to provide an appropriate command line tool for scripting. NOTE: Don't put arduino-serial.c into your Arduino/libraries/CmdMessenger/ directory or CmdMessenger won't compile anymore. We provide a Max5 / MaxMSP example (/Max5 folder) because historically that has been included with previous distributions of Messenger. The inclusion of a MaxMSP sample is not any kind of recommendation over other languages however.
