Adds a close function pointer template parameter to hal::Handle. This allows default destructors in many places.
The status parameter has been removed from close functions; in most places it was not used. Where it was, an error is printed instead.
Fixes error when >3 are constructed- in java, m_filterAllocated[index] would be evaluated before the bounds check and throw IndexOutOfBounds, in c++ a vague assertion error would be thrown.
Makes DoAdd static in c++
Makes the error message when HAL_SetFilterSelect fails consistent with java
If the interrupt edge tests are running while under heavy CPU load (like building wpilib) they are prone to failure since the interrupt thread doesn't have enough time to set up callbacks. The interrupt edge tests now copy the original AsynchronousInterrupt test, which has a 0.5s delay after the interrupt is enabled. Running the new interrupt tests while building allwpilib causes far less failures than the old tests.
If one of the *Init() functions takes several multiples of the nominal
loop time, the callbacks after that will run, then increment their
expiration time by the nominal loop time. Since the new expiration time
is still in the past, this will cause the callback to get repeatedly run
in quick succession until its expiration time catches up with the
current time.
This change keeps incrementing the expiration time until it's in the
future, which will avoid repeated runs. This doesn't delay other
callbacks, so they'll get a chance to run once before their expiration
times are corrected.
The other option is correcting all the expiration times at once, which
would starve the other callbacks even longer so that the callback
scheduling returns to a regular cadence sooner. The problem with this
approach is if a previous callback overruns the start of the next
callback, the next callback could potentially never get a chance to run.
Add LEDReader and LEDWriter helper interfaces to facilitate composing simple patterns into more complex ones, e.g. LEDPattern.solid(Color.kBlue).breathe(Seconds.of(0.75)). Pattern composition relies on changing out the write behavior; for example, offsetBy increments the indexes to write to; while blink will switch between playing a base pattern and turning off all the LEDs.
Add a view class for splitting a single large buffer into smaller distinct sections, which is useful for dealing with long chained LED strips mounted on different parts of a robot. Views cannot be written directly to an LED strip (in fact, trying to do so won't even compile).
Adds some utility methods to the Color class for interpolating between two colors, and support color representations with 32-bit integers to avoid object allocations.
