Non-Classmate DS Problems

[Tom Line]

How many startup processes do you have running on the PC? Is this a PC that kids have access to on a regular basis: i.e. has it been loaded full of non-robotics related garbage that is slowing it down?

I only ask because We've used a 1.4 ghz celeron Dell Lattitude 510 with 512 of ram (now a 1.6 pentium M Lattitude 600) with absolutely no issues performance wise. The first thing I did was to wipe the computer to clean off all the fun programs (limewire, etc etc etc) that tend to get installed.

You talked about using a 2nd cRIO you have with that laptop in the first post. Does the same thing happen when you switch cRIOs?

It's my work laptop, so it's full of work-related non-robotics garbage

For what it's worth, the CPU overhead is about 4% before I open the DS application, so I suspect that it's not other applications running in the background that are causing the problem. I have noticed in other situations (my desktop PCs, for example) that when Windows Update is running there is no evidence. In other words, I'll be like "gosh this PC is running slowly" and then the PC will be like "but the CPU is only loaded to 4%" and then I'll be like "what about network activity?" and the PC will be like "no, I'm not doing anything" and I'll be like "huh." and the the PC will be like "oh, I've just downloaded an update, would you like to install it now?" and then I'm like "dangit!". [To use the parlance of the day.] I've got WU turned off on this laptop for exactly this reason.

Do you see any difference in processor utilization based on which tab on the DS is selected?

That version of the DS updates some UI components more often than it should... I'm not sure of the implementation of those updates, but it's possible that the machine's graphics hardware (or lack there of) could be causing the big performance decrease. Just a thought.

I have seen these exact same symptoms, ( No Code, Watchdog Timeout, No Communications cycling every few seconds) using the Classmate DS after it has been suspended and restored. I tried exiting the software and suspending from the Windows login screen and the same thing happened.

Restarting Windows without rebooting the Crio restored normal operation. I'll try to re-create the situation and look at processor loading later.

This could easily happen before a match but there is no indication of a problem until it's too late to reboot.

Hopefully the update will help.

Can you verify the version of the DS you are seeing this issue on? It is on the Diagnostics tab.
