WebDMA (robot tuning via a web interface) w/easy install released

[virtuald]

WebDMA 0.2 is now available for download at http://code.google.com/p/webdma/

This is a better packaged version of WebDMA, with a few feature improvements. Of particular interest to FRC teams, I have released an installer that installs the object files for WebDMA on your robot, and copies the header files to the needed locations for Wind River. There is also a sample program installed for Wind River as well that allows you to control two motors on your robot with the web interface as a demo. All you need to do to use WebDMA on your robot is install the install package to your development computer, and then run the install program to copy the necessary object files to your robot.

While this is very easy and painfree for beginners to install and use, of course I must give you this disclaimer since a program installed by the installer writes directly to the robot to install the object file:

WARNING: The provided installer will WRITE DIRECTLY TO YOUR ROBOT and modify files on it via FTP.

While I have tested this and this works just fine for our team on our cRio with no ill effects, I cannot be held responsible for your robot. This installer is not sanctioned or associated with National Instruments, Wind River, or FIRST Robotics. In particular, this may void your warranty, render your cRio useless, and COST YOUR TEAM A LOT OF MONEY.

If you are a student: DO NOT DOWNLOAD AND INSTALL THIS ON YOUR ROBOT WITHOUT ASKING THE ADULT LEADER OF YOUR TEAM.

But seriously, it works just fine for me though. And if you have problems, let me know.

While I have yet to test this version out, great job! Looks like you poured in a lot of work. I hope teams find this a very valuable tool.

WebDMA 0.2.1 is now available to download. This release fixes a bug where WebDMA would only launch once when you were running your code in debug mode on the cRio. Now it should load and unload with your robot code as expected.

Download available from the WebDMA Google Code project site. http://code.google.com/p/webdma/

Does something similar exist for Vex?

No idea, I have zero experience with the Vex controller. The main reason this works on a cRio is that it is controlled over an IP network and vxWorks has a semi-reasonable network stack. Add the fact that vxWorks allows multiple threads and this works quite nicely without interfering with the rest of your robot's operation.
