This can be dangerous as it refers to a temporary, and GCC 9.0 warns about
its use. Instead add std::initializer_list overloads to common places it
was used in an initializer_list sense.
* Renamed LinearDigitalFilter to LinearFilter
* Filter base class removed since it wasn't useful
* C++: std::shared_ptr<> replaced with double parameter
* ErrorBase: Use magic static singleton for globals
* ErrorBase: Add testability features for global errors
* Make WPIError definitions inline functions
(This works around cross-DLL variable issues on Windows)
Fixes#1726.
* Update MSVC arguments
* Fix json allocator
* Fix simulation diamond
* Bump gtest
* Remove empty varargs in unit tests
* Replace test case with test suite
* Remove deprecation warning in optional
* Remove need for NOMIXMAX to be defined in wpilib headers
The functions in Threads.h are in the frc namespace. `using namespace frc;` in
Threads.cpp doesn't put their implementations in the frc namespace, so linker
errors occur when attempting to use them in robot programs.
To fix this, one can either wrap them in a namespace block or prepend
`frc::` to the implementation's signature. Based on past discussion, I
opted for the namespace block.
* Fix C++ ShuffleboardComponent template type
* Fix `WithWidget(WidgetType&)`not being properly capitalized
* Fix data members across dll boundaries by using enum for built in types
Resetting the flag should only occur in Enable() and Reset().
IterativeRobotBase needs the flag to remain set to print epochs after
disabling the Watchdog.
Add a Sendable wrapper for VideoSource objects.
Add convenience methods for adding video sources directly to containers
so users won't have to manually wrap video sources.
The 2019 FPGA image switched the output of auto SPI from plain bytes to a
sequence of 32-bit words (timestamp, then words with the byte values in the
least significant byte of each word).
In addition to changing the HAL and simulators to reflect this, add piecewise
integration support to wpilibc/wpilibj SPI to take advantage of the timestamps
and use it in the ADXRS450 gyro.
Notifier has one thread per instance because the callbacks must be
asynchronous. Watchdog callbacks can be synchronous, so this overhead
can be done away with via a scheduler thread akin to what the HAL
Notifier does.
