Rebuilt last SRX-related commit with latest checkout.

Change-Id: I9f10418580275dae5cd07d740d401d45ee44e276

C++: Added Magnetic Encoder sensor types
C++: API for changing status frame rates updated to use paramEnums.
C++: Added Setting nominal and peak outputs for closed loop modes.
C++: Added current-closed loop
C++: added vcomp mode
C++: Added unit scaling (rotations and rpm)
C++ Added allowableclosedlooperr
C++: Added auto zero position on index pin
C++: Added pulse width decoder API
C++: Added multiplicands in status frames, increasing the max reported pos and max rpm.
C++: Added SetClosedLoopOutputDirection() for reversing slave output and reversing single-direction closed loopoutput.
C++: Added generic ConfigSet and ConfigGet for future flexibility/features.
C++: Added IsSensorPresent
Java: Added Magnetic Encoder sensor types
Java: Added unit scaling (rotations and rpm)
Java: Added current-closed loop
Java: added vcomp mode
Java Added allowableclosedlooperr
Java: Added auto zero position on index pin
Java: Added pulse width decoder API
Java: setForwardSoftLimit and setReverseSoftLimit takes double instead of int so underneath we can support rotations instead of native units.
Java: Added generic SetParam and GetParam for future flexibility/features.
Java Added isSensorPresent

Purpose

The HAL is a hardware abstraction layer that provides a uniform interface that can be used to access a number of primarily I/O features in the underlying platform. The features include:

  • Analog input, accumulation and triggers
  • PWM, Relay and Solenoid output
  • Digital input and output
  • I2C and SPI communication
  • Encoders and counters
  • Interrupts and Notifiers

The initial goal is to allow a higher level like WPILib to support both the CRIO and the upcoming Athena platform only by changing which version of the HAL it's running on.

Editing

You can always use any text editor and then build with Maven. There are also eclipse project files so that it can be edited in the same eclipse environment that teams develop with. For the AthenaXX, this can be found in the root directory of this project. It imports as an FRC Robot C++ Eclipse project. The Windriver project can be imported from the src directory.

Building with Maven

There are multiple build targets that the HAL supports. Instructions for setting up the environment and building each of these is described below. Current targets are listed below:

  • All: All of the following targets.
  • include: The header files for the HAL.
  • Azalea: CRIO C++ build.
  • AthenaXX: Athena Dos Equis C++ build.
  • AthenaXXJava: Athena Dos Equis Java build with auto-generated JNA wrappers.

Output from each build target is placed in the directory target/<target-name>. So, the Azalea output is placed in target/Azalea.

All

Note: Windows only due to the Windriver requirement.

  1. Ensure that C:\WindRiver\gnu\3.4.4-vxworks-6.3\x86-win32\bin is on the system path so that ccppc and arppc can be accessed.
  2. Set the environment variable WIND_BASE to C:\WindRiver\vxworks-6.3.
  3. Ensure that $HOME/wpilib/toolchains/arm-none-linux-gnueabi-4.4.1/bin/ is on the system path so that arm-none-linux-gnueabi-g++ and arm-none-linux-gnueabi-ar can be accessed.
  4. Checkout and install the NI-Libraries from Github: https://github.com/first/NI-Libraries.
  5. Run the following maven command: mvn clean install
  6. Success
