The folks over at LeJos have released a new version of NXJ. This is the API for the java virtual machine that they have created for the NXT. Version 0.5 has a bunch of new features including:
- MAC OS X support
- Faster LCD writing
- Bigger file directory, longer file names
- Execute program from flash (gives lots more RAM)
- Garbage collector (not real time yet)
- RCX comms using Mindsensors NRLink adapter
- Faster more accurate Motor regulation
They've also added some more examples to get you up and running faster as well as done a slew of new bug fixes. Check out their forum for the full details.
