Issue Details

I have a VI that uses the LabVIEW Interface for Arduino Toolkit that generates the following warning when I run my application:
Warning 1073676294 occurred at VISA Read in LabVIEW Interface for Arduino.lvlib: Send Receive.vi->LabVIEW Interface for Arduino.lvlib:Digital Write Pin.vi


One of the reasons this error occurs is when the digital pin being written to is not configured as an output. To configure the pin properly, in the Functions Palette, navigate to Arduino Interface for LabVIEW » Low Level VI » Set Digital Pin Mode.vi and include it in your block diagram as follows:

The pin you are writing to should indicate the proper digital signal with the proper configuration.

Additional Information

Note: The package LabVIEW Interface for Arduino (LIFA) has been replaced with LINX. It is highly recommended to migrate to LINX as there will be no further development for LIFA. See How To Download Digilent LINX For LabVIEW? for more information.
