Louis is a open source braille printer made with Java and Arduino, powered by LibLouis
- Windows: Just copy the dll that matches your architecture (from the lib/dll folder) and paste it into your windows / system32 folder
- Linux: Yeah..(sigh) First of all you should download and compile(remember root!) LibLouis. Then copy some files: lib/Linux/RXTXcomm.jar goes in /jre/lib/ext (under java); lib/Linux/[machine type]/librxtxSerial.so goes in /jre/lib/[machine type] (i386 for instance) Make sure the user is in group lock or uucp so lockfiles work. An example location of jre its in /usr/lib/jvm/java-8-oracle/jre/
The arduino source code is in LouisPrinterArduino repo
