removed classes from wpilib
 

I tried loading the code base from last year and noticed that there are quite a bit classes missing now. This includes things like the RobotDrive class and the DigitalInput class. I just wanted to give programmers a heads up that once you update, last years code may not work.


*and as always, remember if you plan you use last years code you MUST open source it

yes i have noticed this too, it is quite strange, there will be no arcade drive this year im assuming saying thats whats missing from our code?

Re: removed classes from wpilib
 

What? That seems odd. I was looking through the C++ documentation that detailed all of the classes, and RobotDrive was included. And I'm sure it's not an outdated version because it includes the new Watchdog replacement.

I think that MUST should read "SHOULD HAVE ALREADY open sourceD it". If you haven't already open sourced it at this point, I think you are too late. The competition started yesterday.

Maybe Chief Delphi should have an open source announcements forum just for this purpose.

Where in the rules does it talk about being allowed to use open source code? I looked through the rules and couldn't find any reference to it. I remember that last year they had a rule saying any open source code was considered COTS, but I can't find that for this year.

a COTS item is something you can get from a distributor and can be made available to and supplied to every team if need be
software free or not falls under this definition

Re: removed classes from wpilib
 

In the first section of the manual there is a glossary that defines COTS parts. Specifically in section 1.6 COTS the note says

Re: removed classes from wpilib
 

I looked at this years WPILib manual that has doxygen documentation of all the classes. I saw RobotDrive included.

I think it's all set now. They were having issues before with having the most recent release ready. Seems to be fixed.

Re: removed classes from wpilib
 

You have some other problem. None of these classes were removed.

Use the following if you want arcade drive. Tank drive is easier.

Linear Arcade drive:


int m1 = 0; //Temp Variables
int m2 = 0; //Temp Variable
int x = 0; //Joystick X
int y = 0; //Joystick Y
Joystick JoyHoy = new Joystick(1);
PWM motor1 = new PWM(1);
PWM motor2 = new PWM(2);

/*
I usually declare and initialize separately like I do for C++, but for simplicity sake I didn't.
*/

while(teleop) //arbitrary while loop, its the teleop
{
Y = JoyHoy.getY();
X = JoyHoy.getX();
m1 = 127 * y + 127;
m2 = 127 * y + 127;
motor1.setRaw((int)(m1 + m1 * x));
motor2.setRaw((int)(m2 - m2 * x));
}

edit:
also regulate the PWM, as is, the code will generate invalid PWMs

On the topic of WPILib changes, they changed "SetLeftRightMotorSpeeds" to "SetLeftRightMotorOutputs" without updating the documentation. Took me an hour of compiler errors before I finally looked in RobotDrive and figured that out.

Which document is not updated? We'll get that fixed.

Page 35, WPI Robotics Library User's Guide, January 5th, 2011. Are you with WPI?

No, but I'm one of the developers of WPILib for C++.
