When there is more than one ultrasonic sensor, only the last sensor
instantiated would work due to incorrect array index management. This
replaces the previous approach with range-based for loops like the C++
implementation.
Supersedes #1589.
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.
Most of the MotorSafety implementation was moved into the MotorSafety base
class. SafePWM's inheritance of MotorSafety was moved into PWM to
eliminate Java needing a helper class.
In Java, a helper class for Sendable (SendableImpl) was added due to
lack of multiple inheritance.
HAL_ReadInterruptRisingTimestamp and HAL_ReadInterruptFallingTimestamp
return time as a double. Instead, keep the raw integer count and move the
double conversion into the C++ and Java code. This enables comparison of the
time with other timers.
PR #1300 supersedes it, but won't be merged until the 2020 season. Since
SynchronousPID hasn't been used during a season, it would be best to
just remove it to avoid breakage when we deprecate and remove it again.
- Build both debug and release binaries
- Append "d" to debug libraries in the style of opencv
- Split shared and static classifiers
- Add raspbian support
Originally, the command was restarted every time the scheduler was
executed if the button was pressed. #1340 changed this behavior in a
breaking manner.
Since https://github.com/wpilibsuite/allwpilib/issues/786 has been
closed as not a legitimate concern, there is now no reason to use
IterativeRobot over TimedRobot. It's a drop-in replacement that's
strictly an improvement in terms of execution jitter.
To migrate, one simply has to replace the IterativeRobot subclass in
their robot code with TimedRobot.
This is necessary for modularization.
Move the wpilibj CameraServer classes to the cameraserver package.
Move the edu.wpi.first.wpilibj.vision package to edu.wpi.first.vision.
To avoid code breakage, add deprecated copies of the wpilibj classes to the wpilibj jar.
