RobotPy 2010.beta2

I've just released a new version of RobotPy (Python for FRC), 2010.beta2. The RobotPy site has moved to FIRST Forge at the encouragement of Brad Miller at WPI; please update your bookmarks. The new location is:

http://firstforge.wpi.edu/sf/projects/robotpy

Major changes from 2010.beta1 release:

Separate packages for the Python core (interpreter and libraries) and the WPILib module. The Python core itself no longer depends on WPILib. This decoupling will allow for separate releases of WPILib for different years (e.g. for beta testing or maintaining old robot code).
Dynamic loading support for binary modules; many of the standard Python modules are now dynamically loaded (as is WPILib). This will make it easier to distribute additional modules as separate packages in the future as well (e.g. NumPy).
RobotBase, SimpleRobot, and IterativeRobot classes are now provided.
You can now derive Python classes from PIDSource, PIDOutput, SpeedController, and Joystick and pass the derived classes to WPILib (e.g. PIDController). This enables custom PID control in Python.

The wiki pages at FIRST Forge contain the most recent documentation. In the coming weeks I plan to work on improving the documentation further; currently it mostly describes the differences between the C++ WPILib and the Python version.

I expect to complete translation of 294's 2010 robot program to Python on Wednesday. When I post it for download I will also make an announcement here.

Re: RobotPy 2010.beta2

I have a complete robot program already coded up, all it needs are comments

Re: RobotPy 2010.beta2

If you don't mind :).

Re: RobotPy 2010.beta2

well crap.

I accidentally deleted it all, so it looks like i have to remake it :(

back this one up

Re: RobotPy 2010.beta2

i even made a computer testing interface for this one:

too lazy to copy the bbcode

Re: RobotPy 2010.beta2

i tried installing robotpy today, and it didn't work

Could you elaborate? Did you get any error messages in NetConsole? In order to help you get it working, I need more detail than simply "it didn't work".

Re: RobotPy 2010.beta2

we didn't have netconsole, all we got was watchdog/no code

You should definitely enable NetConsole to see what's going on. If it's simply "no code" that means the Python interpreter isn't starting. Watchdog likely means your Python code is raising an exception. NetConsole will show the details of any exceptions being raised.

How do I do that?

See http://first.wpi.edu/FRC/frccupdates.html. There is a client download link and instructions for setup of netconsole under the C/C++ Team Update 4.0 section.

Future versions of the Imaging Tool will make it easier to enable the netconsole server portion. It's installed on the cRIO already, just not enabled by default in the C++ version.

Re: RobotPy 2010.beta2

oh, what port is this on?
