New Features in LabWindows™/CVI 2015

Building on the latest improvements to the new LabWindows/CVI optimizing compiler, LabWindows/CVI 2015 includes version 3.3 of Clang, the C language compiler front end to the LLVM compiler infrastructure.

Latest Features in LabWindows/CVI


Increased Performance With New Optimizing Compiler

Generate optimized code and create custom warning levels using the updated compiler based on the industry-standard LLVM compiler infrastructure with Clang C front end.

Updated Build System and Debugger

Edit code while compiling source files and see faster build times overall. Attach and detach the debugger to a running process and build files in parallel.

Support for OpenMP Parallel Programming

Easily add parallelism to existing code without significant edits using the portable and scalable OpenMP API.

Source Code Browsing and Formatting Tools

Navigate source files with ease using a function pull-down list and improved browsing. Create cleaner code with batch formatting and auto-indentation.

Reliable Data Streaming and Storage APIs

Achieve efficient, lossless data streaming between networked applications using the Network Streams API. Advanced TDMS functions add high-performance streaming to disk.

More Idea Exchange Features From Customers

Improve productivity with features for function navigation, project folder organization, and customization of graph and plot display styles.
