The videos below were made with a Webcam and the E6240 board from Atmel. E6240 designed base on the QT60240 IC and QMatrix technology. The videos were made with the factory default setting for this board (intent of using bare hand).
QMatrix™ technology employs transverse charge-transfer sensing electrode designs which can be made very compact and are easily wired. Charge is forced from an emitting electrode into the overlying panel dielectric, and then collected on a receiver electrode which directs the charge into a sampling capacitor which is then converted directly to digital form without the use of amplifiers.
Keys are configured in a matrix format that minimizes the number of required scan lines and device pins. The key electrodes can be designed into a conventional Printed Circuit Board (PCB) or Flexible Printed Circuit Board (FPCB) as a copper pattern, or as printed conductive ink on plastic film.
Designed for the evaluation and development of applications using the QT60160/QT60240 IC, the E6240 kit includes an evaluation assembly, cables and QmBtn™ software. The assembly has a serial (USB) interface allowing connection to a PC for control and data viewing using QmBtn. |
