hello Coding Badly, thanks for this first answer
I try every COM port available in my computer and the result is the same. My strip led doesn't light. I show you in this photo the port com available. I have COM1 and COM2
I explain you with more details:
firstly, i use only arduino software : (software parameter COM is on COM 2) I add a initialisation code in arduino program in order to know if my electric installation is ok and i program a red light during 2 seconds then green light 2 seconds and finally blue light 2 seconds. I upload the code in teensy 2++ and my strip led light correctly.
Secondely, i try to modify the processing code and change the "0" at port line to [1] or [2]. I run the processing program (arduino code is in the teensy) and the strip led doesn't light.
Do you think the problem is about the COM port or perhaps there are problems with Java or RXTX ?
Sorry for my english, i am french, thanks for next answers
