Watch Dog Not Fed...

[shades23]

Any help?

[jmartin]

Can you give more information? What language are you using, when does it happen, etc.

[shades23]

Java happens almost every time we run the whloe robot seems to drop comm.. compresser "flickers" as does the drive and everything else

Check for wireless interference. It may help to move your D-Link to somewhere else on your bot.

Does it happen when tethered directly to the cRio? directly to the d-link? wireless?

[shades23]

Happens when we run wireless

Is your router located away from things like motors, power converters, and metal?
Is the router wired as shown in this diagram?

[PandaHatMan]

Most likely positioning of router.

Also, make sure your router is powered by the transformer plugged into the 12V port on the bottom of the PD board. Most teams don't know this, but that port on the bottom of the PD board will provide a constant supply of 12V until the battery is around 4V or lower.

If it is system WD errors you are seeing, I'd flip to the Charts tab where you can view packet loss and latency. You can post a photo of the chart if it doesn't make sense.

You should be able to use this to compare different mounting options and different settings of the radio.

Honestly, I would just disable watchdog. I haven't gotten it 'fed' enough and its just easier to not deal with it. As far as I know, there is no difference in not having watchdog. I haven't used it for the year's I have been a programmer and the programmer before me hasn't either.

If there is a benefit to having watchdog enabled or a disadvantage to having it disabled, would someone please tell me?

I deleted the portion of my post about the User Watchdog errors. It is off by default and I assumed that you were probably talking about System ones.

The System WD cannot be turned off. It is one of the primary safety features. Code on the robot cannot control outputs unless the DS is in relatively consistent communication with the robot.
