EV3 API ≠ NXT API?

[ChioChippp]

hello guys,

does anyone know, which the API differences between EV3 and NXT are?

i've been wondering, since a functional NXT VI won't run on my new EV3 brick. (NXT Invoke and Property Node not supported on EV3)

thanks in advance!

HI ChioChipp,

the Software to programm the EV3 brick is different from the NXT software. National Instruments has developed the LabVIEW API however that is compatible with both brick types. Maybe you still have the older toolkit that only supports NXT?

Try installing the new one: http://sine.ni.com/nips/cds/view/p/lang/en/nid/212785

I hope that helped. Please let me know if it didn't.

Best,

Anna

Hi Anna,

thanks for the reply!

Unfortunatly I've already installed the latest tool. 😞

My biggest problem is, that there are no Property Nodes available for the EV3. Unlike for NXT...

So in my previous post someone suggested to use VIs instead of Property Node.

However, I don't know which provided functions possess the same abilities as the NXTOutput Property Node.

For example:

having the actual pecentage of full power returned, that the NXT firmware is applying to the output (in my case the EV3)

best regards,

Chio

PS: sorry for my bad english, if it's the case 😐

HI,

I think they were right. You have to use VIs and avoid the property nodes. What do you need the power output for?

Maybe there is a way around this. Maybe you can also post your VI (or a part of it).

Best,

Anna

Hey,

damn I accidently hit the solution button.... well, nevermind.

Unfortunatly I'm not allowed to post the VI, due to a confidentiality agreement.

I need the power output to regulate the active motors. 

As another example: I need to know, how many times the wheel has rotated.

Because I'd like to initialize the motor. And if the motor does not rotate, for example 2 times clockwise, the programm will abort.

I guess I have to find a way around property nodes somehow. But thanks a lot!

Best regards,

Chio
