What’s New

VxWorks is really amazing RTOS with special features, few are given below:

Support for C++17 – VxWorks is the first RTOS to support C++17. C++ is most widely programming language for the embedded industry. If you run a project team, you will enjoy the lower burden on code maintenance and associated costs. If you are a product manager, you will celebrate the improved runtime performance of your application. And everyone will benefit from the improved security and safety features.

Boost Productivity with Boost 1.71.0 – VxWorks now supports Boost 1.71.0, another RTOS first. Boost offers free, peer-reviewed software libraries for use in C++. The latest version contains substantial updates to many of the Boost libraries, including updates to nearly half of the Beast core.

Python –  Developers can use Python to develop applications for VxWorks.
