Part Number: MSP-CAPT-FR2633
a customer of mine has developed a touch keyboard w/ our captivate technology...
he is asking whether (and if yes, how) is possible to detect multiple keys pressed at the same time (or if there will be a dominant one)...
thanks a lot in advance
Thank you for your post. If their application requires detection of multiple touches, they'll need to make sure mutual mode is used, not self-capacitance mode, for the electrode matrix (see CapTIvate Technology Guide > Capacitive Sensing Basics > True Matrix Capability section for more details).
First, I would highly recommend that they read through the entire CapTIvate Technology Guide to better understand how CapTIvate works. When they do, they'll come across the CapTIvate Technology Guide > MSP-CAPTFR2633 Development Kit > Sensor Panel Demonstrations > CAPTIVATE-METAL Demonstration > Basic Button Touch section which talks about detecting multiple keys.

In reply to James Evans:
Hi James, We've produced several keypads (4x4 touch buttons) but would like greater sensitivity to button touch as well as proximity. We tried to make both more sensitive but are facing some challenges:
Again, the keypad is 4x4 (16 buttons), and I sent you the project offline. Thanks a lot in advance.
