Re: [FRC Blog] 2017 Motor (and Servo?) Controllers and MXP
 

FIRST gave us a list of legal MXP all-in-one active boards, not the individual devices we plug into the roboRIO expansion port or the 3rd party MXP all-in-one active boards.
What we plug into them is up to us.

Ah, now I understand. Thank you.

Another thing to consider is that this is only the approved list of active devices. Under R69 from last year, this is the definition of a active device:

The ADIS doesn't control and deliver a source of electrical energy, so it wouldn't need to be on this list.

Re: [FRC Blog] 2017 Motor (and Servo?) Controllers and MXP
 

It should be able to act as an output for any device. If I were to guess, it outputs +6V on the center rail and GND and signal are simply passed through.

Also, remember that in competition servos need to be controlled by the RoboRIO.

This list is only for active devices. My understanding from the 2016 rules (R68/R69) is that it's only considered active if it generates motion from the output pins. Something like the ADIS16448 is a sensor, and therefore flals under their passive device label.

You can read more from their blog in 2014 if you like, but rules may have changed since then.

Based on the SD540C Library documentation (http://www.mindsensors.com/reference/FRC/html/Java/) it looks like the SD540C is just a CAN enabled dumb speed controller, rather then a Talon SRX competitor.

Re: [FRC Blog] 2017 Motor (and Servo?) Controllers and MXP
 

It appears to have a few "smart" features, like getting the limit switch and changing brake/coast while driving. Overall, I think I'd still pick the SPARK over this at the moment, seeing how it offers the same limit switch stop feature (it's not hard to code in anyway) and costs $5 less with the option of buying through Amazon Prime.

However, something to note is that the manual mentions encoder inputs and currently says:
If they can add this feature soon (and before Kickoff soon, people won't design for features they don't have) and it works well, then the Talon SRX may be seeing its last season of being the dominant motor controller.

So I guess nothing came out of the BLDC motor controller being demoed by CTRE at CMP last year?

Re: [FRC Blog] 2017 Motor (and Servo?) Controllers and MXP
 

Yes, absolutely. The Servo Power Module is designed to inject power to any servo and pass through the signal line. We do interface with the signal line to so you can read status of each channel via LED feedback, but if you are running a PWM signal this will just work.

It is designed to accept a voltage range from 9-20v. ( 7v is the brownout, but 9v is required to start) We just posted our quick start data sheet so people can dig a bit more into it. http://www.revrobotics.com/content/d...11-1144-QS.pdf

And Units are available now at REVrobotics.com and soon to Amazon.

Re: [FRC Blog] 2017 Motor (and Servo?) Controllers and MXP
 

I'm wondering about this too. Maybe they couldn't convince FIRST to legalize a variety of brushless motors in time? They could also have not finished it for FRC use yet, since it appeared to only have an input for the HERO board.

The Huskie Board is now in full production with virtually unlimited supply over the course of the season. Our inventory shown is "built and on hand", but most backorder quantities will be 3-5 days. The board is available here: http://playingwithfusion.com/productview.php?pdid=88

The Huskies will be releasing more content shortly, so stay tuned!

Happy New Year!
