Read Battery Voltage

[Greg_Reynolds]

I don't see a NXT Toolkit library function (or a NXTSyscall Method) for reading battery voltage on the NXT.  I see that it can be done with a NXT Direct application, but I'd like to do this in a NXT Toolkit application. Is there a way?

Take a look at http://nxtasy.org/2007/04/19/battery-level-nxt-g-block/

Interesting, I'll try this out. Where can I find info on the iomap and the ui module?

Thanks much!

Is a way to do this on LabView?
code please

Hi Isaac84,
you can use the "Get Battery Level.vi", but it is on PC site and only possible if your are connected to your NXT.

Hope it helps.

It worked, thanks Mike.....


By the way do you know why each time i try to compile some code for the NTX this error shows up:



Error 1003 occurred at Invoke Node in NXTToolkit.CompileOrCancel.vi->NXTToolkit.TargetAgent.vi
Possible reason(s):

LabVIEW:  The VI is not executable. Most likely the VI is broken or one of its subVIs cannot be located.  Open the VI in LabVIEW using File>>Open and verify that it is runnable.

Method Name: Run VI

VI Path: C:\Archivos de programa\National Instruments\LabVIEW 8.5\vi.lib\addons\NXTToolkit\gcompiler\Backend.LEGO\NXT.Compiler.Core.vi


Thank you Mike, i use labview 8.5 and i have already mass compile everything

Hi Isaac84,
can you upload your vi, or a picture of it? Maybe you use a vi which is not supported on the NXT.

I uploaded the Vi to the forum, is a VI that senses the farest distance in any of the four cardinal ppoints ( North , south, east,west).
Maybe you can run this Vi and tell me if worked

Thanks

Hi Isaac84,

do you get this error independing from the vi you want to transfer to the NXT, or with a special one? Where do you get the error?

Yes it happens every time i try to send anything to the NXT. I doesnt happend when i use the NXT direct connect blocks and in debug option, they work ok. But it happens when i try to compile anything to the NXT......
Did the code i sensd to you worked ok on your robot?
