Processing + Firmata + Library

in Integration and Hardware • 3 years ago

Hey guys,

I have a arduino-board successful connected to Processing. Now I want to use a library (which I already have used in the Arduino enviroment) in Processing. In the Arduino software I use normally #include <SLCD.h> to import the library but that doesn't work in Processing. How can I import C(?)-libraries in Processing. Was seeking for hours and I am sorry to bother u with that but u are my last hope ;)

Thx in advance! Best,
Jason

You have to use a bridge between native code (C/C++) compiled to a shared library (.dll or .so or .dynlib) and Java.
Usual ways is to use JNI or JNA Java libraries.

Hi phi.lho,

thanks for the quick reply. Mmmm ... why can Processing not use something like #include? I think Arudino based on Processing. I have no clue about bridges and C/C++. Do you have any tips/hints where I can find good tutorials/instructions/whatever?
Or is it maybe possible to copy such a bridge from an arduino-folder and modify it for Processing?

best

Because Processing uses Java, and #include is C/C++. You can't mix them without some incantations. Learning how to do this is possible, but quite hard as it assumes both a knowledge of Java and C.

uuarrgs, not the answer i was looking for ;) but thx.

But once again. How can Arduino do something (when it's based on Processing) what Processing can't? Doesn't make sense to me?!

Nobody had the problem before to use a library like wire or whatever when working with Firmata?
