ATEVK1070B: 7 Button Capacitive Touch


This kit is for the evaluation and development of applications using the AT42QT1070 ('QT1070') 7 Key QTouch™ Integrated Circuit (IC).

In this example, the QT1070 is shown working in 'Comms' mode, allowing configuration of settings and reading of Reference and Signal values to aid evaluation and development. The EVK1070B can be connected directly to a PC via USB or User application via an I2C compatible bus.

The EVK1070B is configured to allow setup of 1 to 7 keys (or 1 to 6 keys plus a Guard channel)

The QT1070 chip is also able to operate in ‘Standalone’ mode see the datasheet for more details.
