If we decide on all Jaguars, and possibly up to 20 speed controllers, that's a lot of money, substantially more than just trading for a few victors.
Sounds like a pretty straightforward decision for you then.

Re: Advantages of the Jaguars?

Adam,
Since the Jaguars have a large, and light colored case, might I suggest the prudent use of a red and black magic marker now before the screws are removed. I would hope that the new rules for this season will allow the end limit inputs to be controlled by digital outputs of the controller. That way, you have the best of both worlds.

Al, when we unpacked them we marked them with some sharpie for that reason (totally not my idea at first, had read someone reccomend it here on CD). A student one upped me and is designing labels we can print that look rather nice.

I'm not sure about the digital outputs controlling the limit inputs. Wouldn't it be more reliable to simply toggle the motor in code?

Hi Scott,

Please explain precisely where the ambient temperature is being measured.

Re: Advantages of the Jaguars?

The LM3S2616 microcontroller has an integrated temperature sensor. Each H-bridge period initiates the measurement of the motor current, the battery voltage, the ANA input value, and the temperature.

I slightly disagree

our team was going to run 100% victors for our system (6 total)

bur we discovered the one advantage the jag has over the vic (and is 2009 legal)- at really low speeds, the jag has MUCH better control than the vic. for our shooter, this is crucial in dump mode- so we switched the one. this came important- this switch won Buckeye this year.
