6.5.2
The QTouch libraries for ATtiny40 devices are supported for the following compiler tool chains.
Tool
IAR Embedded Workbench for Atmel AVR.
IAR Compiler.
6.5.3
For an overview of QTouch method based capacitive touch acquisition, refer
QTouch Acquistion method.
The QTouch Library for ATtiny40 device allows for Sensor configuration and Sensor Acquisition
parameter setting. Based on the input Sensor configuration, the QTouch Library takes care of the
capacitive touch acquisition data capture operations on the external capacitive touch sensors.
The captured Touch Data and Touch Button ON/OFF Status information is then available for user
application.
The diagram below indicates a Typical Sensor arrangement using the Tiny40 device. For one
channel configuration, two ADC pins are used for acquisition. For number of touch buttons
greater than one, no extra ADC pins are used.
used to support upto 12 Touch Buttons. The Touch Buttons may be connected anywhere on the
said port pins.
The Sensor numbering is always in the increasing order of Port pin.
