Setting up the environment

To use Workbench you need to configure it so that it knows about your robot and the programs that you want to download to it. There are three areas that need to be set up. 1. The target remote system, which is the cRIO that you will use to download and debug your programs. 2. The run or debug configuration that describes the program to be debugged and which remote system you want to debug it on. 3. The FIRST Downloader settings that tell which program should be deployed onto the cRO when you are ready to load it for a competition or operation without the laptop. Creating a Remote System in Workbench Workbench connects to your cRIO controller and can download and remotely debug programs running on it. In order to make that connection, Workbench needs to add your cRIO to its list of Remote Systems. Each entry in the list tells Workbench the network address of your cRIO and has a kernel file that is required for remote access. To create the entry for your system do the follow...

Using Wind River Workbench

Wind River Workbench is a complete C/C++ Interactive Development Environment (IDE) that handles all aspects of code development.  It will help you: • Write the code for your robot with editors, syntax highlighting, formatting, auto-completion, etc. • Compile the source code into binary object code for the cRIO PowerPC architecture. • Debug and test code by downloading the code to the cRIO robot controller and enabling you to step through line by line and examine variables of the running code. • Deploy the program so that it will automatically start up when the robot is powered on. You can even use Subversion, a popular source code repository server to manage your code and track changes. This is especially useful if there is more than one person doing software development.

What is the WPI Robotics Library

The WPI Robotics library is a set of C++ classes that interfaces to the hardware in the FRC control system and your robot. There are classes to handle sensors, motors, the driver station, and a number of other utility functions like timing and field management. The library is designed to: • Deal with all the low level interfacing to these components so you can concentrate on solving this year’s “robot problem”. This is a philosophical decision to let you focus on the higher level design of your robot rather than deal with the details of the processor and the operating system. • Understand everything at all levels by making the full source code of the library available. You can study (and modify) the algorithms used by the gyro class for oversampling and integration of the input signal or just ask the class for the current robot heading. You can work at any level. First, something about our new environment. We have about 500x more memory and 40x faster for fixed point an...
