The VEX LCD display is a versatile tool in robotics competitions, allowing teams and referees to output real-time information, interact with menus, and, crucially, keep score during matches. This comprehensive guide will walk you through the process of using the VEX LCD display for scorekeeping, integrating best practices, visual aids, and expert insights. By the end, you'll understand the hardware setup, interface design, and practical applications for using the VEX LCD to track and display scores efficiently.
Keeping accurate, real-time scores is vital in robotics competitions, both for team strategy and for audience engagement. While digital apps and paper sheets are common, the VEX LCD display provides a hands-on, programmable, and visible solution right on the robot or at the field. This article explores how to leverage the VEX LCD for scorekeeping, from setup to best practices, with visual and video references for clarity.
The VEX LCD is a 2x16 character display module, featuring two rows with sixteen characters each. It also includes three programmable buttons, allowing for user input and menu navigation[1][8]. The LCD connects to the VEX Cortex or PIC microcontrollers using a serial Y-cable, with RX and TX ports for two-way communication[1][8]. This setup enables the LCD to both display information and receive input, making it ideal for interactive tasks like scorekeeping.
- Real-time Feedback: Display scores as they happen, ensuring teams and spectators are always informed[3][7].
- Interactivity: Use built-in buttons to increment or decrement scores, reset values, or switch between teams[1][3].
- Portability: Attach the LCD directly to the robot or a field station for easy access[8].
- Customization: Program the display to show team names, match numbers, or custom messages[1][6].
1. Connect the LCD: Use a Serial Y-cable. The 4-pin end goes into UART port 2 on the Cortex. The 3-pin yellow wire connects to the RX port of the LCD, and the white wire connects to the TX port[1][8].
2. Power On: When properly connected, the LCD displays the name of the last downloaded program. If you see a series of zeros, swap the RX and TX wires[1].
3. Button Functions: The three buttons on the LCD can be programmed for actions such as incrementing scores, resetting values, or navigating menus[1][3].
- Row 1: Team 1 Score
- Row 2: Team 2 Score
Each row can show the team name and current score, e.g.,
`Red: 12`
`Blue: 15`
- Left Button: Decrement score for selected team
- Center Button: Switch between teams or reset scores
- Right Button: Increment score for selected team
1. Select Team: Use the center button to toggle between Red and Blue teams.
2. Adjust Score: Use left/right buttons to decrease/increase the selected team's score.
3. Reset: Hold the center button for a few seconds to reset both scores to zero.
During a match, referees or team members can use the LCD to keep a live tally of scores. The display can be updated in real time as points are scored, providing immediate feedback to drivers and spectators[2][7].
After the match, the final score displayed on the LCD can be shown to teams for verification before submission to the official scorekeeper. This reduces disputes and ensures transparency[7].
While the LCD is excellent for local scorekeeping, scores can be cross-verified with digital systems like the VEX Tournament Manager, which handles official submissions and audience displays[2][5].

- Assign Roles: Designate one person to operate the LCD for consistency[7].
- Regular Updates: Update the LCD immediately after each scoring event to avoid memory lapses[2][7].
- Double-Check: At match end, confirm the displayed scores with all teams before submission[7].
- Backup: Keep a paper or digital backup in case of hardware failure[7].
- Practice: Familiarize all operators with the button functions and interface before the event[1][3].
The VEX LCD display is a powerful tool for real-time scorekeeping in robotics competitions. Its combination of visual feedback, interactive buttons, and portability makes it an excellent choice for both teams and referees. By following best practices for setup, interface design, and operation, you can ensure accurate, efficient, and transparent score tracking throughout your event. Integrating the LCD with official digital systems further enhances reliability and audience engagement.
Connect the LCD using a Serial Y-cable: the 4-pin end goes into UART port 2 on the Cortex, the yellow 3-pin wire to RX, and the white 3-pin wire to TX on the LCD. If the display shows zeros, swap the RX and TX connections[1][8].
Yes, the LCD can display any text, including team names, match numbers, sensor values, or custom messages. You can also create menus or debug information screens[1][6].
If the LCD fails, revert to a backup scorekeeping method such as a paper sheet or digital app. Always verify connections and have a backup plan in place[7].
The three buttons can be assigned to increment/decrement scores, reset values, or switch between teams. The specific functions depend on your program logic and interface design[1][3].
The LCD is ideal for real-time, local scorekeeping and audience engagement but should be supplemented with official digital systems like the VEX Tournament Manager for match submissions and official records[2][5][7].
