Does anybody know how, if at all possible, to output text to the LCD of the Driver Station? I would be interested to output debug information for our sensors, etc. so that we can more easily monitor these values without having to lug a laptop around everywhere.

We are using LabView as per team consensus and I'm not so good with it as I am with C/C++... I tried connecting a string constant into the UserData part of the Driver Station User Data VI and it basically gave me the equivalent of a data type mismatch - then again, I don't even know if this is the correct VI to use.

Any ideas?

Short answer:You can't do it

Long answer:By default, the DS loads a program which does not support displaying this data. However, since the DS is basically a linux box, it would be theoretically possible to reverse-engineer the default program and make a new one that COULD display user data(though probably not competition-legal)

Yeah I saw that the DriverStation was ARM9 and gcc and the like can all do ARM compilation easily, but I couldn't find the specific kernel source and modules and such for the DriverStation since it wouldn't be competition legal, not to mention I'm sure they want to keep it proprietary.

Thanks for the response though.
