Timer reports a negative duration if the sim timing is restarted. This
can be worked around by calling Reset(). Other options included:
1. Have RestartTiming() call Timer::Reset() on a list of instantiated
Timers.
2. Have Timer::Get() reset the timer if it notices time went backwards.
This requires dropping const qualification though, which is a
breaking change that only fixes a minor edge case.
Closes#2732.
A lot of these are breaking changes. frc::Timer was replaced with the
contents of frc2::Timer. The others were in-place argument changes or
removing deprecated non-unit overloads.
Based on run of include-what-you-use.org to identify unused include files in various .h and .cpp files.
The changes mostly fall into 3 categories:
- Actually unused includes - copy-paste errors, not removing includes after cleaning up code, etc
- A too-broad include used where a more specific (and hopefully smaller) header will do
- Interface .h files including headers only needed by the .cpp implementation - moving from .h to .cpp
will mean that code which uses the .h doesn't pay the price of processing the header file they don't need
If the 64 bit FPGA timer rolls over, a 32 bit value is added for
the rollover, an artifact of when it was a 32 bit timer.
The 64 bit microsecond timer won't rollover for 500k years so remove the
check for simplicity.
Fixes#2504
These were incorrect and exhibited as warnings on more recent versions of
clang (notably on Mac).
- Use pointers instead of references internally in GenericHID and *Drive
- Leave PIDBase, PIDController, and Resource non-moveable
- Remove the atomic from m_disabled in NidecBrushless
- Make Timer and Trigger copyable as well as moveable
- Implement custom move constructor/assignment for SendableChooserBase
Also comment out some unused variables that caused clang warnings.
Add unit-taking overloads to the following classes:
- IterativeRobotBase
- LinearFilter
- Notifier
- TimedRobot
- Timer (HasPeriodPassed only)
- frc2::PIDController
The corresponding non-units-taking functions have been deprecated.
The return value of TimedRobot::GetPeriod() was updated.
This is a breaking change, users should use to<double> to get the value in seconds.
Other return values, e.g. Timer::Get(), have NOT been updated due to much wider use.
Timer didn't have working move semantics because mutexes aren't
moveable, meaning the default implementations were ill-formed.
MotorSafety wasn't locking its mutex.
The old headers were moved into folders because doing so avoids polluting
the system include directories.
Folder names were also normalized to lowercase.
