TSS 3.0 is based on two main conversion
algorithms for the capacitive measurement. The
first algorithm uses the Freescale TSI module
available on new ARM Cortex-M4, Kinetis
or ColdFire+ MCUs. The TSI module allows
increasing penetration of touch in different
consumer and industrial markets with robust
performance.
The capacitance digitized value is processed
to avoid false touch detection and minimize
electrical noise influence.
Finally, the decoding layer enables the key
detected to be included in a decoder control
that treats the detection as a part of the
keypad, slider or rotary interface. TSI is an MCU
peripheral designed to scan up to 16 electrodes.
It is a highly robust touch-sensing method which
also minimizes the need for CPU resources to
process touch-sensing signals. Conversion time
is guaranteed while the resolution is not reduced
across typical hardware conditions.

TSS Design and Development Tools
The TSS library supports different kinds of
hardware designs, printed circuit boards
(PCB), capacitive film, flex PCB and more.
For guidance on best practices for electrode
and layout design, download the application
note, “Designing Touch Sensing Electrodes”
(document AN3863) from freescale.com/TSS.
Freescale has a full set of development tools
that include the capacitive touch Tower
System plug-in starter kits (TWRPI kits)
which, in conjunction with Tower System
boards for Kinetis, ColdFire+ and S08 MCUs,
enable advanced development through rapid
prototyping. TSS 3.0 includes development
support using FreeMASTER graphical interface
for sensitivity calibration, offers a library
configuration GUI, and a series of demo
applications and technical documentation.
