Continuing my R+D into arduino and processing I have setup a basic example of serial communication using a button connected to my Arduino that sends a value to the Processing. I also have an LED connected but this can be dropped out if not required.
Been playing with processing and the arduino in the last couple of weeks. When setting up Processing I ran into the notorious RXTX mismatch error - similar to
RXTX Version mismatch Jar version = RXTX-2.2pre1 native lib Version = RXTX-2.2pre2
To solve this, I did some scouting around the web and found a few clues but here's a detailed approach on how to fix it on mac osx 10.7.
