How to resolve error : VISA Clear in LabVIEW Interface for Arduino.lvlib:Init.vi ?

[harrydtt]

i am getting Error -1073807343 when i try running my int block diagram. when i unplugg the Arduino (USB) and reconnect, it's getting 5002 and 5003 error codes. i tried increased the delay in the "USB / Serial" case structure to 10000 like this :" https://decibel.ni.com/content/thread/9762?tstart=0" but still not working. i tried many times but it's just work in a few times then not work. please help me 😞 .

So if you are working with LIFA you have to check some points:

1- Have you downloaded the firmware to Arduino?

2- Sometimes you need to press the reset button when you run your VI.

3- The Arduino IDE recent version doesn't work with the Firmware library from LIFA, you have to use a previous version.

4- There are other libraries for Arduino like Linx, try them.

I hope these points would be helpful.

thanks you. i did everything you say, no other libararies, just have LIFA_BASE.ino in my Arduino; downgrade to Arduino IDE 1.5.6 but it's still no work 😞
