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.

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.
Set the environment variable WIND_BASE to C:\WindRiver\vxworks-6.3.
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.
Checkout and install the NI-Libraries from Github: https://github.com/first/NI-Libraries.
Run the following maven command: mvn clean install
Success
