Tracking down a stuttering JAG/CAM drive.

That's the one I recommend using for robot/team specific data that you really care about.

It's completely unused in the default dashboard and robot framework in order to set it aside exclusively for team use. It's in the WPI->Driver Station palette.

I guess I need to look at this to understand the mechanism.
Our status is being sent to an LED on the Cypress module.
That's done by the DS (not the dashboard... right?)

Can I just speed up that item through the DS, or do I need to send custom data to a custom dashboard and then get it to the Cypress..... I'm so confused...!

I never use the compressor status check or any compressor calls outside of Begin. I like pulling breakers to keep the compressor from running.

Sounds like you got the memo that I missed.
Pulling breakers...... excuse me !!!!!

Yea, the Cypress outputs are directed by the DS app.
I was thinking of Dashboard lights.

I haven't looked at the latency of Cypress outputs.
It all comes across in the same packets, but I don't know if they are sliced into every packet or only every nth packet.

DS data that includes Cypress info is sent eery packet. The latency could be off by a packet depending on when you are updating things. Also, the high and low priority data really isn't that different. The names refer to what is done when there isn't room for all of the data to fit. The normal case is for all data to be sent each packet. The slow dashboard is due more to the Build Data method of metering out the reads and reporting data twice a second.

I forgot how you split up the IO data for the default Dashboard to spread the impact of reading it all out a bit .

Phil,
Does TU #19 address your issues?
