hi,

sorry it was really a crap reply of my very own I'm afraid ;-)

The architecture is :

Host Machine : USB (rxtx java) <-> Arduino + BlinkMCommunicator w/ BlinkMs plugged.

This is really like BlinkMSequencer example for Arduino except I use a Java framework of my own emulating BlinkM/MaxM commands frames posting to the USB Arduino Serial port (19200, 8-N-1)

In my case I'm trying to get RGB values thx to the BlinkMCommunicator lib deployed on Arduino Board from a particular BlinkM LED of address '0x09' back to the host.

To do so, I first post the get RGB color as usual, in a same form as the BlinkMSequencer, then I was supposing it could be ok to post the modified frame back to the Serial from the Arduino board and decrypt it back w/ RGB values.

For the moment, I just don't succeeded in getting the values from the BlinkMCommunicators APIs or had a 2 ways RXTX comm issue.

I gave up this some days ago and have to dive into that again.

So, my first question is :

Is there some java Rxtx code sample somewhere than can achieve the get RGB color w/ architecture I mentioned (eg: no Processing nor Arduino IDEs, just plain old java).

Second question :

I saw an interesting project called firmata (firmata.org). Maybe, it could be cool to directly deal w/ the Arduino hardware description from the host and some blended access to I2C bus thi sway. Okay, I just didn't dig really into it yet but in case if you know something about it, I take it.

best,

Hi Tod,

I just post commands to Arduino Board in the same vein as BlinkMCommunicator from an OSGi/USB application.

Coming from that, I thought it would be possible to send a getColor cmd and then get the modified byte refs back trough Serial comm using RXTX.

In the other hand, I understand going directly to an I2C solution would be more elegant in this case.

As well, ever heard about firmata ? Sounds like it could be possible to trick some nice host to Arduino/ThingM equipements communications with that.

Pb : I just code in plain Java/Eclipse, no Processing/Arduino stuff ...

Any idea is welcome.

BTW thanks for the good ThingM stuff

regards,
