Notify Operator and Driver 5 seconds before the end of each shift

[dcowden]

We cannot know from the FMS whethre we won auto or not. But, the operator and driver can see the display that says it at the beginning of teleop.

Functionality: a latching button on the operator panel should indicate if we won auto or not. Once that's set, the code should notify driver and operator when each shift is about to end.

Specifics:

• we need a livetunable value that operators can change that is the length of time ( in seconds) the notification happens before end of a shift. lets call this "T"
• a switch on the operator panel wil lindicate if we won ( the operator toggles this at beginning of teleop)
• we should see notifications T seconds before each shift ends.
• we should write this in a unit tested class so that the logic is verified
• we should make it easy to change how driver and operator are notified. choices are:
  • operator fedora LEDs
  • rumble the driver controller and the operator fire switches/buttons

Here is an AI prompt we can use to get a starting point for this code:

i am on an FRC team in the 2026 season. there are these scoring shifts that are based on who wins autonomous ( see game manual). i need to write a class that will track when each period ends. the goal is to notify our team when our shift is within N seconds of starting or N seconds of ending. N is configurable. i am triggering LEDs that are like traffic lights. green means your shift. yellow means N seconds till end of your shift. red means other shift. yellow means N seconds till start of your shift. I want the logic to be unit testable, so the actual light logic should be based on enums. eventually we'll use it in a trigger to set led state. the class should take as its constructor if we won Auto, and an N period. then, a getState() should return a numeration of the current state ( see above). Even though we are using LEDs, our enum should talk about states as: YOUR_SHIFT, SHIFT_ENDING, THEIR_SHIFT, SHIFT_STARTING. there should be a getter to get this hift, we can use a trigger to change things when it changes. Give me a java class and some junit unit tests for it. Before you write it, give me the logic you plan to use from the frc game
