Many VEX V5 products contain their own internal processors and run on a special Operating System known as 'VEXos'. This Operating System is written entirely by VEX Robotics, and harnesses the flexibility and power of VEX hardware for the diverse needs of education and the rigors of competition.
Setting up your project structure to use the parsekeybindings script is also pretty straightforward. Create a directory called docs in your top level directory, and put the file controller.png in this directory. Create a file called constants.h and assign your button mappings inside of it (see constantsexample.h). Add the lines builddocs: path/to/constants.h, and python genericparsekey. PROS is a lightweight and fast alternative open source operating system for the VEX Cortex and VEX V5 microcontrollers. It features multitasking, low-level control, and Wiring-compatible functions to help harness the full power of the Cortex and the V5.PROS is build with developers in mind and with a focus on providing an environment for industry-applicable experience. VEX Robotics is educational robotics for everyone. VEX solutions span all levels of both formal and informal education with accessible, scalable, and affordable solutions. Beyond science and engineering principles, VEX encourages creativity, teamwork, leadership, and problem solving among groups.
VEXos allows for advanced programming features and an enhanced user experience. The best way to ensure that your V5 system is functioning properly is to keep the firmware up to date. This is done simply by opening VEXcode, then plugging your V5 Robot Brain into your computer and following the prompts. The Brain will then automatically push out the latest updates to any V5 device that is connected to it.
A standalone VEXos updater is also available for both Windows and Mac.

VEXos Version 1.0
Released August 2018- Initial Release
Like the V5 System, the VEX ARM® Cortex®-based Microcontroller, VEXnet Joystick and VEXnet Key 2.0 each contain its own firmware. To update this firmware, you will need to download the VEXnet Firmware Upgrade Utility, the VEXnet Key 2.0 Firmware Upgrade Utility and the VEXnet Serial USB Driver.
The VEXnet Firmware Upgrade Utility overwrites the Master Code on the VEX ARM® Cortex®-based Microcontroller or a VEXnet Joystick to the latest version.
Note: By default, the Upgrade Utility will NOT overwrite any User Code in the Cortex Microcontroller with Default Driver Control Code. If you wish to revert your microcontroller to its default settings, make sure that 'Default Code: ON' is properly selected.
