Changing parameters on the fly?

[DjScribbles]

Does anyone know a slick way of changing some parameters on the fly. My wife is going to attempt to tune our PID routines we have setup with crumby default values; and I want to avoid modifying a #define in code and redeploying 80 times in a day.

I've thought about attempting fopen or something like that, but that still requires me to filezilla something down there ( or SSH/terminal somehow into the robot)

If the fopen is on the right track, I'm not quite sure how I go about cracking into the robot, so a link to a guide or some instructions for that would be awesome.

Are there any sneaky methods that we could use from the driver station maybe?

Thanks in advance!
