The labels are currently sent as an array. C++ and Java SmartDashboard classes do not currently support sending arrays.

The strings are labeled top-to-bottom, left-to-right from "DB/String 0" to "DB/String 9". Each String field can display at least 21 characters (exact number depends on what characters). To write to these strings:

Java: SmartDashboard.putString("DB/String 0", "My 21 Char TestString");

C++: SmartDashboard::PutString("DB/String 0", "My 21 Char TestString");

To read string data entered on the Dashboard:

Java: String dashData = SmartDashboard.getString("DB/String 0", "myDefaultData");

C++: std::string dashData = SmartDashboard::GetString("DB/String 0", "myDefaultData");

The Buttons and LEDs are boolean values and are labeled top-to-bottom from "DB/Button 0" to "DB/Button 3" and "DB/LED 0" to "DB/LED 3". The Buttons are bi-directional, the LEDs are only able to be written from the Robot and read on the Dashboard. To write to the Buttons or LEDs:

Java: SmartDashboard.putBoolean("DB/Button 0", true);

C++: SmartDashboard::PutBoolean("DB/Button 0", true);

To read from the Buttons:

Java (default value of false): boolean buttonValue = SmartDashboard.getBoolean("DB/Button 0", false);

C++ (default value of false): bool buttonValue = SmartDashboard::GetBoolean("DB/Button 0", false);

The Sliders are bi-directional analog (double) controls/indicators with a range from 0 to 5. To write to these indicators:

Java: SmartDashboard.putNumber("DB/Slider 0", 2.58);

C++: SmartDashboard::PutNumber("DB/Slider 0", 2.58);

To read values from the Dashboard into the robot program:

Java (default value of 0.0): double dashData = SmartDashboard.getNumber("DB/Slider 0", 0.0);

C++ (default value of 0.0): double dashData = SmartDashboard::GetNumber("DB/Slider 0", 0.0);
