278932 447401 Compiler Defines return compile errors when porting code from LabWindows/CVI 2009 to LabWindows/CVI 2010.
In LabWindows/CVI 2009, multiple Compiler Defines are separated by a comma then a space. However, in LabWindows/CVI 2010, multiple Compiler Defines are expected to be separated by only a space. When compiling code in LabWindows/CVI 2010 that complies with the LabWindows/CVI 2009 Compiler Defines format, illegal character build errors are returned.
Workaround::
Remove the commas separating the Compiler Defines.

The LabWindows/CVI ANSI C integrated programming environment helps you create custom engineering applications. You can use it to manage your project, edit and debug source code, build a user interface, and test code output and performance in one streamlined, tabbed workspace. LabWindows/CVI includes tools for advanced debugging, code documentation, and system deployment so you can integrate source code control, requirements, and data management systems. The software also makes it easier to quickly acquire data from GPIB, USB, serial, Ethernet, PXI, VXI, and FPGA instruments using the built-in instrument I/O libraries, built-in instrument drivers, or the two interactive measurement assistants.

This tutorial walks through developing a simple windows form test tool in LabWindows. It does not use any vendor test equipment or libraries though. It is interfacing by a simple USB to Serial protocol to an Arduino to test LEDs, buttons and a potentiometer.







Since 1976, National Instruments has equipped engineers and scientists with tools that accelerate productivity, innovation and discovery.
