Commands are no longer able to outlive their schedule-site's scope,
regardless of how they were scheduled (set as a default command, bound
to a trigger, or manually scheduled)
As a consequence, default commands need better tracking so the default
command setting can be released when their scope exits and the next-most
appropriate default command can be rescheduled (eg, an opmode sets a
default command, then the globally-scoped default is restored when the
opmode exits). Some complexity is required here to make it work well for
edge cases.
Like `schedule()`, `setDefaultCommand()` will immediately start the new
default command if called inside of another command to avoid 1-loop
delays. However, this does not apply when called by the _current_
default command, as it would result in attempting to cancel the default
command while it's mounted (which is impossible and would throw an
exception)
```java
class Robot extends OpModeRobot {
final Drive drive = new Drive();
final CommandXboxController controller = new CommandXboxController(1);
public Robot() {
// global default command, active unless overridden in an opmode or command
drive.setDefaultCommand(drive.stop());
// global trigger binding, always active
controller.rightBumper().onTrue(drive.setX());
}
}
@Teleop
class ExampleOpMode extends PeriodicOpMode {
public ExampleOpMode(Robot robot) {
// opmode-specific default command
robot.drive.setDefaultCommand(robot.drive.operatorControl(robot.controller));
// opmode-specific binding
robot.controller.leftBumper().whileTrue(robot.drive.stop());
// opmode-specific binding that takes precedence over the global binding
// because it happens last; it "wins out" over the `setX()` binding
robot.controller.rightBumper().onTrue(robot.drive.selfTest());
}
@Override
public void periodic() {
Scheduler.getDefault().run();
}
}

- Remove status return from HAL level (clock getting should never fail)
- Remove 32-bit timestamp expand function
- Make monotonic_clock.hpp (formerly fpga_clock.hpp) header-only and
move to root hal include directory
Makes Java `Alert.Level.ERROR`, `Alert.Level.WARNING`, and
`Alert.Level.INFO` proper aliases (instead of separate enum constants
with the same value).
Cleans up Python tests.
Makes the Alert tests more consistent between languages.
I left "free speed" alone since that's the technical term for it. In
general, velocity is a vector quantity, and speed is a magnitude (i.e.,
a strictly positive value).
This PR also replaces the speed verbiage in MotorController with duty
cycle.
Fixes#8423.
Easier then the last one that put everything in a sub namespace. By
prefixing the name less things break, and intellisense will be less
confusing to new users during the transition.
User code:
- OpModeRobot used as the robot base class
- LinearOpMode and PeriodicOpMode are provided opmode base classes
- In Java, annotations can be used to automatically register opmode classes
Additional user code functionality:
- OpMode (string) is available in addition to the overall
auto/teleop/test robot mode
- OpMode does not indicate enable (enable/disable is still separate)
- The HAL API uses integer UIDs; these are exposed at the user API level
as well for faster checks
- User code creates opmodes on startup (these have name, category,
description, etc).
DS:
- DS will present opmode selection lists for auto and teleop for
match/practice. During a match, the DS will automatically activate the
selected opmode in the corresponding match period.
- For testing, an overall mode is selected (e.g. teleop/auto/test) and a
single opmode is selected
Future work:
- Command framework support/integration
- Python annotation support
- Unit tests (needs race-free DS sim updates)
- Porting of examples

Now rgb() and color constants are supported.
Changed from constructor to fromString() factory function to enable
directly returning color constant values.
Support joystick outputs, including Rumble and LEDs.
Also requires an update to Joystick descriptors, as that has also
changed in mrccomm to support showing what outputs are supported.
