What is the V5 Firmware Utility?

The VEX V5 Firmware utility is a tool that providers users with options that aren't available through VEXcode V5. It can provide vital information through the information button, when working with VEX Support to determine possible causes for hardware issues. The V5 Firmware Utility is also vital in competition settings, since turning a V5 Brain into a Field Controller is necessary for running competitions. Running battery diagnostics is another option through the V5 Firmware Utility, allowing users to identify possible issues with the V5 Battery.

Update V5 Brain Firmware

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.

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. You can update the V5 Brain's firmware using the V5 Firmware Utility.

Battery Diagnostics

Viewing the battery diagnostics screen allows you to view coloring of the battery cells indicating if some cells are not holding a charge compared to others, which is visible using a color-coding system of green, red, and black.
