7 Generic QTouch Libraries for 2K Devices
7.1 Introduction
This section provides information about the QTouch library Acquisition Support for Tiny devices
with 2K Flash memory. These libraries have the same API’s as Generic libraries, except for a few
which are not supported.Information about the API’s are provided in touch_api_2kdevice.h file
which is placed at location mentioned in
7.2 Devices supported
The list of different devices that are supported by the QTouch library for 2K devices is given
below:
7.3 Salient Features of QTouch Library for 2K Devices
NOTE:
7.4 Library Variants
For Different library variants available for 2K Devices, please refer Library_Selection_Guide.xls
7.5 QTouch API for 2K Devices and Usage
This section describes the different API’s used during touch sensing. Using the API, Touch
sensors and the associated channels can be defined. Once touch sensing has been initiated by
the user, the host application can use the API to make touch measurements and determine the
status of the sensors.Refer

No AKS, no Power Optimization and no pin configurability support in case of 2K device
libraries.
The change information like library status flags which reflects if there is any change in
Reference values, rotor slider position change status flags etc are not part of the 2K device
libraries.
1 to 4 Touch Buttons can be configured. Supports maximum of 4 Buttons.
Libraries in variants of 1, 2 and 4 channels are provided.
2K device libraries are supported only for IAR.
Library API’s are same as Generic QTouch libraries.
Support for more than one pair of SNS and SNSK ports are not available for 2K tiny
devices.
