Hi,
1. Yes, you are right.The added wire will only affect the sensitivity. You can just think it as you only touch a part of the button, if the wire is enough long. And the Connector will also introduce parasitic capacitors。
2. CapTIvate Touch is closely…
One wishes - such "high detail" was announced previously. Pay is 'scant' for we (few) outsiders - thus our Google Ratings (and captive clients here) drive our time & effort.
There IS a 'method of compromise' - which meets (both…
Hi,Ling
As temperature and voltage change, sensitivity is affected, so calibration is performed periodically.
In addition, captivate's phone board demo design has the following structure,

Hello Juha,
The Captivate peripheral has advanced EMC features to offer the best immunity to conducted noise (10-V RMS), EFTs (4-kV), and ESDs (15-kV) per the IEC 61000-4-6, IEC 61000-4-4 and IEC 61000-4-2 system-level standards, respectively. Please…
Hi Tobias,
I'm confused with your design to locate the active button very close to the GND(the inactive button), which could be a strong base capacitance for the active button. I you are designing for terms of EMC performance, I would introduce you to…
Hi Michael,
It's been some time, but I did want to circle back to this thread. I re-visited the tuning for the CAPTIVATE-BSWP evaluation panel, and I was not able to get an EMC tuning that I was happy with using the current battery-optimized layout…
Hi Ling,
I'll paste my generated code below. I'm expecting my first button to use TX pin CAP1.2 (connector C7) and RX pin CAP1.0 (connector C5).
It looks like it lines up to me, but I must be missing something. I probed every pin on the connector…
Hi Romain,
The answers you are looking for are all in the CapTIvate Technology Guide . I highly recommend reading through the guide, as it will provide a lot of useful information to you.

Thank you for posting this question.
The illustration shown is a simple example that represents what might be used for a simple keypad or similar.
Buttons can be distributed as far apart from each other as needed.
There are, however, a couple of guidelines…
