Problems with arduino labview Interface

[Sajeel]

i tried to interface labview with ardiuno but it didn't work. it can't control the simple led control on ardiuno uno board. 

there is an error warning in lifa base compiling i think its the reason of this problem. how it can be fix????

You won't find much support for LIFA since LINX has replaced it.  That doesn't mean you can't use LIFA, it just means less people are using it, so less people are around to help you with it.  My advice is to checkout LINX instead, it has some pretty good support, and lots of videos walking through the process.

I think you are not setting the COM that you need, if you can put a screen shot of your VI maybe I can help you, or use Linx, its more easier and faster, but LIFA works good, let us know if you solve your problem

i have solved it..,....... 

now my circuit is working properly.

I had the same problem . I sovle it by upgrading by Arduino IDE

Solving the problem is not possible without first staring the problem.  This usually starts with creating your own thread if you have different issues from OP.  That being said read the link I provided to LINX.  It has a simple LINX Firmware Wizard... in the tools menu which just downloads the firmware without needing the IDE.

hello,

excuse me

how did you solve it?

I tried downloading lifa_base again but didnt work

let me know asap

LIFA has been replaced with LINX.

Reread the message above yours for further guidance.
