Well, the name is rather clear, but if you explained in more detail what you expect this command to do, perhaps we can help you.

I wanna control LegoNXT using Iphone (through Processing).

At one point, I wanna run the program stored in the LegoNXT triggered using Iphone.

When I keyed in nxt.startProgram(); in Processing, it says that the function startProgram() does not exist when I tried to run the program.


So I'm wondering if this command exist in Processing or if it exist then how do I use it.


Thanks phi.lho for being the first to reply and hoped you can help me out.

I can only tell you that indeed, startProgram() doesn't exist in Processing out of the box. Now, I wonder what nxt object is. Do you use a contributed library?
How do you plan to control LegoNXT with iPhone? Using a PC as interface? Directly? If the latter, how do you run Processing applications on the iPhone?

As you see, you let us having to guess lot of things. Unless you expect somebody having the same setup to answer you?

I'm using NXTComm library for Processing ( http://jorgecardoso.eu/processing/NXTComm/).

This is the flow: Iphone > Processing (PC) > LegoNXT

So I just hope someone can give me some advice on how to use the startProgram() command.

Should I dl a library or use it directly or any suggestion?

Aha, it is better when you explain the context! Thanks for the link. I see the library seems to be for Windows only, I suppose that's what you use.
I suppose you have installed the RXTXcomm.jar too.

If I look at the JavaDoc of the LegoNXT class, I mostly see motor and sensor commands, no startProgram around. Where do you found out this function name?
And, again, what kind of object nxt is?

I've found the command startProgram() at some other sites which is for other programs used to communicate to LegoNXT.

Btw the nxt object is to create an object out of the LegoNXT class so that you can use the commands as stated in the
JavaDoc u have seen.

The format would be like nxt. Command();     

You can name any object name like abc or whatever you wish for. Anyway I dun think Processing can use that command..

Hope someone who is smart and great enuff to create the library to use the startProgram() command for Processing.

Once again thanks phi.lho
