Updating VEX IQ (1st gen) Firmware with VEXos Utility – VEX Library

Using VEX IQ (2nd generation) with App-based VEXcode IQ? See this article.

VEX IQ Smart Devices, including the Brain, Controller, Smart Motor, and sensors, contain their own internal processors and run special software called firmware. VEX IQ Firmware is called VEXos.

VEXos is a robotics operating system that harnesses the flexibility and power of VEX hardware for the rigors of competition and the diverse needs of robotics education. This operating system uses real-time processing for repeatable operation at the fastest possible speeds.

The VEX IQ Brain is coded using VEXcode IQ. VEXcode IQ requires the most up-to-date VEXos because:

Each update of VEXcode IQ will require the latest version of the VEXos firmware to be installed on the Brain before projects can be downloaded.
VEXos updates include fixes for known bugs and the software additions needed to operate any new devices incorporated into the VEX IQ product line.
Updates allow use of advanced programming features.

Updating firmware regularly ensures that VEX IQ Smart Devices function properly. If your Brain is not connecting to VEXcode IQ, or the Brain icon is orange in the VEXcode IQ Toolbar, you must update your firmware.
