Public response to: VEX LCD Usages?

This is the public response for the thread VEX LCD Usages? that @Wup123 made

(I already PM this to him, but for other teams that may want to know). To answer your question, LCD screens can be used to choose autonomous programs (so that you can have multiple), read battery life, check up on sensors, read motor speed, or even do something fun like display a message. It is dependent on your programming skills.

You can also use the LCD as a way to display a pre-match checklist. In combination with a VEX speaker, the LCD is useful for making sure that all the basic stuff like batteries plugged in, rubber bands replaced, wires double-checked, etc. before every match. It’s always tough to lose an easy match because of a stupid mistake.

We use one for tuning control loops and autonomous routines by displaying the numbers on the screen in real time. We also showed the error, velocity, acceleration, target velocity, and motor power of our flywheel last year for the driver control load feeder. It turned out to be really useful…if the guy learned how to use it. I highly recommend learning to use the buttons as well; they are really useful sometimes.

LCD’s are still important in most matches.
With our robot, we contain an LCD screen that contains 3 buttons.
Our first button(On Held);

  • Shows the battery voltage of the primary battery on line 0
  • Shows battery voltage of the expander battery on line 1

Our second button(On Held);

  • On the right of the LCD screen, it has an auton picking Dial(Potentiometer). And to pick the autonamous, you press and hold the second LCD button, then as you turn the potentiometer, it switches autons and displays which auton is selected on the LCD screen. It shows this on line 0.
  • Eventually show the side the robot will be playing that auton on line 1.

Our third button(On Held);

  • Shows the battery voltage of the backup battery on line 1.
  • Maybe battery checker that indicates weather batteries should be changed or not on line 0.

There are two lines that you can place text in an LCD screen, the top is line 0, the bottom is line 1.
