Hello, all. I want to make a mod that ties up a real arduino and minecraft redstone in a virtual world.

 

I've been doing research and what most people reccomend is the RXTX library, the most useful page on that is found here.

however this requires you install a .dll file, and this is viewed as very shady no matter where you are.

Is there an alternative? Maybe a way to send raw serial data through the port? I've been studying assembly languages, so that option may not be bad. If possible, i'd like a library that is made for arduino.

thanks in advance, it means a TON.

You can try communicate over the wire. TCP/IP might be too have, but there are other, lighter, options out there (their names just escaped me ).

Arduino doesn't have network capabilities, sadly. I'm expecting users to have the bootloaders  installed, and connected via USB, the same way development was made to work.

I don't think there is a way to get around using a .dll.

But you can, instead of installing it, put in in the same folder as your mod (Or any other folder) and specify the folder using

System.setProperty( "java.library.path", "/path/to/libs" );

Field fieldSysPath = ClassLoader.class.getDeclaredField( "sys_paths" );
fieldSysPath.setAccessible( true );
fieldSysPath.set( null, null );

(Normally you have to specify the path before starting the program as a jvm argument, but this hack can change it afterwards)

 

Also you might get better answers in an arduino forum, than in a minecraft modding forum

I had trouble deciding the forum to post this to myself. 

is there a way that i may pack it in to the .jar file itself?

Not really. dlls have to be unpacked to be used.

But you could pack in in to the .jar and have your mod automatically unpack it. That would work.

Thanks, i'm going to read up on this. Any clue how long it would take to unpack a 23Mb .dll file on a standard 7200 rpm hdd? My guess is 5 seconds max. The library itself is less than 23Mb, but i want an upper limit.

 

You can always add a shield with bluetooth or wifi capabilities.

That is something to keep in mind.

i am, just going to be using to be supporting the uno, and other, common devices.

like I said, i want this to be in a normal dev enviroment.

I've done some work for Arduino Leonardo and other devices...
