Java embedded framework for create sensors drivers via i2c bus
With this framework you can develop your own libraries on Java, Groovy or any JVM language
This framework allow you to easy change and use any IO provider
under development this code work, but be refactored
You need first https://github.com/452/java-i2c-tools
