Peripherals
5. Peripherals
The starter kit has a set of peripherals that showcase some of the features of the CPT112S device.
Be aware that some CPT112S I/O routed to peripherals are also routed to the breakout pads. This must be taken into consideration
when using the breakout pads for your application.
5.1 Capacitive Sense Touch Pads
The kit has 12 capacitive sense touch pads. The touch pads are connected in order to pins CS04 - CS11 of the CPT112S
SLEXP8008A. After the touch pad inputs have been processed by the touch qualification engine, the CPT112S SLEXP8008A will out-
put the result through I2C.
The capacitive sense inputs can be configured for different thresholds, debounce counter values, scan periods, gain, scanning meth-
ods, touch time-outs, and touch exclusiveness using the [Xpress Configurator] in Simplicity Studio. The device outputs can also be
configured for different pin polarities and drive strength.
See the CPT112S SLEXP8008A Data Sheet for more detailed information on the different configurations.

5.2 Capacitive Sense Slider
The CPT112S SLEXP8008A has 4-channel slider connected to CS00, CS01, CS02, and CS03. The slider output can be viewed in
[Capacitive Sense Profiler] using the [Slider] view, and information about the slider position and touch are sent by the CPT112S
SLEXP8008A device thorugh the I2C EB protocol to the host processor.
The capacitive sense slider inputs can be configured for different thresholds, debounce counter values, scan periods, gain, scanning
methods, touch time-outs, and touch exclusiveness using [Xpress Configurator] in Simplicity Studio.
