eStop Robotics CCI board

[Dale]

I just heard from eStop's tech support. eStop has confirmed there's a problem with at least some of the boards and they are working with Microsoft and Microchip to figure out a solution. Those who purchased a CCI are supposed to be getting an email shortly. If they can't fix it they'll be recalling the boards.

We have a CCI at our shop and are running Windows 7. I'll speak with our programmer and see if ours is having the same issues.

Sounds like E-Stop has some good Tech Support.

eStop has solved the CCI problem but it requires the CCI be updated. New orders from eStop claim to have this bug fix incorporated. Here's is what was sent to eStop customers who purchased a CCI:
-----------------
Dear Valued Customer:

eStop Robotics is pleased to let you know that we have resolved the Custom Controls Interface (CCI) connectivity issue with Windows 7.

It was necessary to update the Microchip PIC® MCU on the CCI to correct the Windows 7 connectivity issue, therefore, we need to replace the CCI that you currently have.

Replacement Procedure:
eStop Robotics will replace the CCI that you originally purchased with a new CCI that includes the updated code.

eStop Robotics will pay the shipping costs for US Postal Priority mail service to your original shipping address.

Thanks Dale.

I don't seem to be a valued customer, so I wouldn't have known if you hadn't posted.
Messages from eStop probably got lost. I need to check my junk/spam folders.
I'll get in touch with eStop.

eStop Robotics has processed all the requests we have received for CCI replacements.

All of the currently shipping Custom Control Interface boards are the updated versions of the CCI and have been fully tested for use in both Windows XP and Windows 7 environments.

All of our customers that received early versions of the CCI were sent an email explaining how to receive an updated CCI at no charge.

As Mark point out below, it is possible that our email message to some customers may have made its way to a junk/spam folder.

Any customer that has an early version of the Custom Control Interface should contact us immediately for a free replacement.

We want all of our customers to know that customer satisfaction is VERY important to us.

The new version of the Custom Control Interface, Basic Layout & Connection Guide is available on our site.

The new version is 1.2 and includes tips and directions for connecting switches and potentiometers.

Ordering information for the CCI is available here.

Hi Joe,

If I were to want to hook up a resistor ladder on a 6-position rotary switch for one of the analog inputs, what rating resistor would you recommend? Something like 15K ohm? Or is there a more recommended value?

TIA,

Mike

Mike,

Your 15k resistors will work fine.

There are two limitations on the resistor size to your resistor ladder question. The first is that there needs to be enough current for the A/D to get a correct value. The second is that there is not too much current draw that the CCI shuts down or overcurrents your USB port. With those two restrictions in mind, its actually harder to find resistor values that would do either of those things. So stay away from resistors that are lower than 10 ohms and higher than 1 M ohm. In other words with some margin, you want the current in your resistor ladder to be between 1 mA and 10 nA.

So with that in mind, and with plenty of margin, use any resistor values from 1k to 100k in your resistor ladder. You can use these resistors with a power rating of 1/8th watt or larger.

Thanks for the response!
