I have just recently noticed that an alpha version of NXJ of lejos exists. I have been playing around with it for an hour or so. I tried running some of the samples and it seems to be downloading with no problems and then running on the NXT.
I have had a few difficulties however so maybe someone here can calrify some things:
1. When I link a program using lejoslink the command line window prints out a lot of garbage and my PC speaker makes lots of noise. Why is this?
2. When i ran one of the samples it works when the USB cable is plugged in but it only runs once. When i turn the NXT off and then turn it on again it just keep ticking but no program runs until i run lejosdl again.
3. Does the USB cable have to be plugged in at all times? Even once its downloaded? Mine doesnt seem to work if the USB isnt plugged in at all times. Kind of a limitation if the robot can only move around with a USB cable in the way.
4. The TestButton sample seems to detect the Enter and Left buttons but the Right button and ESCAPE buttons do not show up on the screen. Bug or some other issue?
Hopefully there will be some FAQ that will grow as time goes on.
