Hello,

new to Arduino and this compiler, however experienced with embedded and LV.

Im able to run editted LV programs on my Arduino Uno. Nice.

How do I go about running a program which can display values from the Uno back to the PC based LV SFP ?

I assume the transfer is via the serial port /USB ?

Is there an example that shows a basic display of say analog input voltage on a LV SFP ?

In the compiler example "serial-monitoring-arduino target" is mentioned a HOST PC vi...however I cannot find this.

Perhaps this is the key example I am looking for ?

or is this not possible for an Uno ?

Thanks for any help.

Yes, that is the example you are looking for.

Thanks for the prompt reply.

I had success the first compile..and then I started to make some edits, and ran into this error.

Error 42 occurred at Arduino Compatible Compiler for LabVIEW.lvlib:ArduinoSketchGenerator.vi

I still get this error even after reverting to the original project and code.

I inserted a status indicator on the status output of compiler.vi in host.vi and received :

Loading configuration...
Initializing packages...
Preparing boards...
Verifying...
Uploading...
avrdude: ser_open(): can't open device "\\.\COM7": The system cannot find the file specified.
An error occurred while uploading the sketch

The uno is connected and working.

Is there perhaps some need to clear the port so it can be found ?

Thanks for your help.
