[357madox]

Hello,

thank you for the video.

I have a problem. when at the last after writing the codes i try the nxj download it keeps showing me error saying "no nxt found is it switched on and plugged in?

i tried reconnection and restarting it but so far its no use can you help me please

@357madox Restart your computer and make sure you installed the driver correctly.Then, try re-flashing the firmware onto the NXT, there might have been a transfer error from before. If that doesn't work, try installing a a slightly earlier version of leJOS on your computer and on the NXT.

I couldn't download the compiled program to brick. The error is:

Failed to load USB comms driver: cannot load USB deiver

(I did that step!)

OS: windows 7 64

This is the error

error: Class names, 'BasicMotorTest', are only accepted if annotation processing is explicitly requested

1 error

@obiegryff Can you send me your code in a private message?

Nice guide. Thanks for the contribution to the community. Even though this guide is for Windows, I still am impressed. I guess most people use Windows instead of Linux anyways so it is more appropriately suited to be in Windows. Thanks

@mercedesbenzformula1 Thanks, and yeah most people use Windows anyway so I guess this guide is best for most people.

Doesn't work for me :/ The tune.java is not compiled when i type in nxjc tune.java

[Mindstormscreator]

Make sure the environment variables are set correctly (pointing to the right locations etc). You might also have to log out and log back in again.

[Damnshid]

@Mindstormscreator Hm now nxjc compiles, but the outcome is a .class file and it cant be uploaded with nxj.bat

[Mindstormscreator]

@Damnshid Make sure you are typing just the name of the file and not the extension (.class, etc). It should be uploading a .nxj file, not a .class file, even though the compilation process does create a .class file.

[Damnshid]

@Mindstormscreator It's just not working :/ I reinstalled the whole thing and now there comes an error while flashing the brick, it couldnt find jfantom.dll

[Damnshid]

@Mindstormscreator could it be possible that this is not working on x64 systems?

[Mindstormscreator]

@Damnshid Yes, that is possible, I do remember hearing things about leJOS only working on x86, you might want to try loading just x86 software including Java software since it should still work.

damn i got a problem by starting a new java project: i don't get the referenced libraries for lejos set in my project :/ - although every time a start a new project i choose "Use project folder as root for soucres and class files"

can anybody help me?!

[Mindstormscreator]

@luki938 Well first of all you need to import the libraries into the project as shown in the video @ 6:32

Then you need to add this to the top of the project to import what you want to use: import lejos.nxt.*;

[luki938]

@Mindstormscreator thx i just deleted eclipse and did everything step by step again - and for now everything works fine ;)

thx ;)

[Mindstormscreator]

@luki938 Glad it worked, good luck coding!

[sankarasubbaiyer]

Thank you so much for the videos. Really helped me a lot. I was following a text instruction from another place and ended up confused. Best Regards, Hari

[Mindstormscreator]

@sankarasubbaiyer No problem. I think I know what tutorial you are talking about; it doesn't have everything you need to know, so I decided to make these video tutorials of literally EVERYTHING you have to do...

[Alichek1987]

Delightfully, I was able =))))))))

Thank you so much !!!!!!!!!!

You really helped me at this stage! ^ ^

[Mindstormscreator]

@Alichek1987 Glad it helped.
