GetLocation() or GetAlliance()

Technical C/C++
1

Hello,

I am wondering how to use either of the two functions (GetLocation() or GetAlliance()) whic gets the location or alliance off of the Driver Station.

I want to make it so that I can have 2 or more different autonomous’. How would I fully implement this?

Thanks,
Davis

You can actually read the joysticks during disabled. I setup a snippet of code this week to read the driver joystick and check if the trigger is held for 3 seconds, and switch to a different autonomous routine.
For reference, here’s that chunk out of my code


static Timer button_combo_timer;
if (BUTTON_COMBO_SWITCH_AUTONOMOUS() == true)
{
    button_combo_timer.Start();
}
else
{
    button_combo_timer.Reset();
    button_combo_timer.Stop();
}

if (button_combo_timer.Get() > 3.00)
{
    button_combo_timer.Reset();
    switch (autonomousMode)
    {
    case AUTONOMOUS_MODE_1:
        autonomousMode = AUTONOMOUS_MODE_2;
    break;
    case AUTONOMOUS_MODE_2:
        autonomousMode = AUTONOMOUS_MODE_3;
    break;
    case AUTONOMOUS_MODE_3:
        autonomousMode = AUTONOMOUS_MODE_1;
    break;
    }
}
switch (autonomousMode)
{
    default:
    case AUTONOMOUS_MODE_1:
    driverStationLCD->PrintfLine((DriverStationLCD::Line) 3, "Using 1");
    break;
    case AUTONOMOUS_MODE_2:
    driverStationLCD->PrintfLine((DriverStationLCD::Line) 3, "Using 2");
    break;
    case AUTONOMOUS_MODE_3:
    driverStationLCD->PrintfLine((DriverStationLCD::Line) 3, "Using 3");
    break;
}
driverStationLCD->UpdateLCD();

Interesting, where would I place that to read it before a match?

Thanks

If your using iterative robot, in

void DisabledPeriodic(void){
}

I’m not sure if your using simple robot though :slight_smile:
