LabView Programming - Do we still need Watchdog?

[Mark McLeod]

I take it back...
I re-checked my notes and I misremembered one part.

This is what happens when a Safety vi trips.

The status on the Driver Station remains "Autonomous Enabled" or whatever field mode we're in.
The Diagnostics Message Window shows this error message each time it happens:

ERROR <Code> -44061 occurred at "Left and Right Motors" in the VI path: Robot Main.vi
<time>23:15:45 01/21/2011
FRC:  The loop that contains RobotDrive is not running fast enough. 
This error can occur if the loop contains too much code, or if one or 
more other loops are starving the RobotDrive loop.

If you have an autonomous that makes several drive moves then it will:

1. do the first drive move for .1 second
2. stop and display the error above
3. do the second drive move for .1 second
4. stop and display the error above
5. etc.

If you have a bunch of moves close together you'll think the cRIO is pulsing.
