Using other Arduino libraries in combo with Processing & Firmata

Hi,

I'm using the Mux Shield II (http://mayhewlabs.com/products/mux-shield-2) which needs a library in order to function. As my project uses both light sensors & the computer display, I was wondering if I could include this Arduino library in my Processing sketch in order to control the display with Processing, and communicate with the Mux Shield (to which the light sensors are connected) using Firmata.

If not, back to the good ol' fashioned processing.serial.*

Thanks!

No. There is NO way to use a C++ library in a Java application.
