CAPTIVATE-FR2633: Tracking two or three capacitive sensors by using 2 generic capacitors hooked to some ports of an MSP430

Part Number: CAPTIVATE-FR2633
Other Parts Discussed in Thread: CAPTIVATE-PHONE

Hi team,

I am posting this inquiry on behalf of our customer. To make sure that I will not miss any information, I will paste here the customer inquiry:

"I need to use TI development kit (CAPTIVATE-FR2633) for tracking two or three capacitive sensors are in the same range of capacity as some of the ons TI placed on the demo board with sliders, proximiy and keyboard configuration (NBO000181 - on a paper label) and the design environment doesn't let me place two identical capacitors in the circuit. So, since I think that the system just cannot be that limited, I am certain that I am doing something wrong and I wonder if you have a solution for this particular job: just have generic capacitors hooked to some ports of an MSP430 micro and see how they do."

Here's the set up of the customer.


It’s just a couple of capacitors inserted into the 48-pin connector.

The customer would like to be able to demonstrate the functionality with moving the capacitors from port to port so that he could see how to accommodate various board configurations, basically with the same level of complexity but with the capacitors being connected at various pins.


Please let me know if there's anything you want to clarify with the customer.

Thanks!

Jonathan

    Hello Jonathan,

    I will send you a separate email to discuss more details. 

    Thanks,

    Hi, 

    I hope that it's only my perception but this is the most confusing way of providing help (not to mention that this case is going like this for at least a week). So, here is the first question (and I hope this is not going to take another week to address): to whom am I "speaking" now? Jonathan or the e2e expert?  I noticed that on the forum there were two messages to Yiding and the idea was for me to talk directly with him but how?

    Could we set a time for a real-time chat?

    Thanks, 

    Alex

    Yiding, 

    Please add to the very concise description from Jonathan that I would like to be able to operate with these capacitors with having one common electrode and also a ground plane that cold be contacted too. 

    Just wanted to let you know that I tried to follow as accurately as possible one of the tutorials TI posted on line (building a test setup with the CapTIvate-PHONE board and even that is not working as described there. So much for my "Prodigy" classification in this e2e forum - most certainly I don't deserve even those 10 points...:).

    Thanks, 

    Alex

    Hello Alex,

    Sorry for the confusions.

    I send a email to your email address Jonathan provided to me last week but did not hear anything back.

    Let me send the email again to you so we can better help you.

    Thanks,

    Yiding
