Robot drive... Output not updated enough.

[AlexD744]

This error message is a frustrating one because it would seem that this error would originate from the RobotDrive class, however, the real problem could be in any part of your code. This displays whenever your code is running too slowly, and will subsequently disable your drive functions (and probably everything else, not sure though, I haven't spent too much time trying the different functions when this has popped up). Anyway, this message appears a lot if you are doing image processing on the cRio because that takes longer than the 20mS loop time. Other (more likely culprits) include infinite loops (or any loop that lasts longer than 20mS), methods that call themselves without end (I had a setMotorSpeed(speed) method that called setMotorSpeed(speed) at the end of it instead of motor.set(speed)), and anything else that potentially stops or slows the code.

It may be helpful to add your own output messages throughout your code, then you will see what is getting called before the RobotDrive message, and it will probably point to the area of code that is causing the stop.
