SystemCore doesn't directly support Servos. It would be possible to still use a Servo Power Module, but those are fairly rare, and we should probably use a different class for that case, so users don't attempt to hook a servo directly up to systemcore. That will depend on what happens with the rules in 2027.
Rev Servo Hubs are a current working replacement for systemcore users.
This is a cleanup of the FlywheelSim class with a few added features.
- One FlywheelSim constructor that takes a plant, DCMotor, and a optional number of measurementStdDevs. The documentation now states how to construct the plant either through LinearSystemId.createFlywheelSystem or identifyVelocitySystem.
- The gearbox, gearing and moment of Inertia (J) are now private final fields. The gearing is determined from the plant in the constructor as well as the moment of inertia. There are getter methods that allow the flywheelSim to return the gearbox, gearing, and moment of inertia.
- The getCurrentDrawAmps function now uses m_x instead of getAngularVelocityRadPerSec in accordance with more accuracy and matches the patter in other sims.
- Added getter methods for the InputVoltage, angularAcceleration and torque
- (Java only) A third getter method for returning the AngularVelocity of the flywheel using a MutableMeasure as a backing field that is set when getAngularVelocity is called. This summarily returns the angularVelocity as just a Measure object. This allows the user of this class to handle unit conversions with less numerical manipulation. Alterations in C++ for this feature were not needed.
LTVUnicycleController is a drop-in replacement with better tuning knobs.
The RamseteCommand examples were removed instead of retrofitted with
LTVUnicycleController because we're planning on removing the command
controller classes anyway, so it would be wasted effort. The
SimpleDifferentialDriveSimulation example shows direct
LTVUnicycleController usage.
The default state for the DS in the simulated HAL is changed to disconnected.
The FMS view is now only editable in DS disconnected state.
This enables more robot and field-like testing of robot code, as the
alliance color and other parameters start in invalid states and are
only set when the DS connects.
Many teams have issues trying to read the DS too early. By switching to an optional, we cause teams to check 2 things. Either 1) they explicitly check, and their code is correct, or 2) they just read .value() and their code reboots in a loop. However, because the DS will eventually connect, this 2nd case is ok, and should theoretically be undetectable on the field.
Accelerometer is hyper-specific to ADXL accelerometers, and Gyro is
less useful now that 3D IMUs are prevalent, and if those IMUs want to
support the Gyro interface, they also need to provide a way to set the
axis used for the Gyro interface, which is confusing. Higher-order
functions (e.g., lambdas) are a more flexible interface boundary than
interfaces, but they didn't exist when these interfaces were
created.
Setting one will set the others, like it does in real hardware.
Add tests for boundary conditions and conversions.
Update PWM sendable implementation to include all forms.
