CapSense
Overview
The CapSense Express™ controller allows the control of six IOs
configurable as capacitive sensing buttons or as GPIOs for
driving LEDs or interrupt signals based on various button
conditions. The GPIOs are also configurable for waking up the
device from sleep based on an interrupt input.
The user has the ability to configure buttons, outputs, and
parameters, through specific commands sent to the I
IOs have the flexibility of mapping to capacitive buttons and as
standard GPIO functions such as interrupt output or input, LED
drive, and digital mapping of input to output using simple logical
operations. This enables easy PCB trace routing and reduces
the PCB size and stack up. CapSense Express products are
designed for easy integration into complex products.
Architecture
The logic block diagram shows the internal architecture of
CY8C20160.
The user can configure registers with parameters needed to
adjust the operation and sensitivity of the CapSense system.
CY8C20160 supports a standard I²C serial communication
interface that allows the host to configure the device and to read
sensor information in real time through easy register access.
The CapSense Express Core
The CapSense Express core has a powerful configuration and
control block. It encompasses SRAM for data storage, an
interrupt controller, and sleep and watchdog timers. System
resources provide additional capability, such as a configurable
I
The Analog System contains the CapSense PSoC block which
supports capacitive sensing of up to six inputs.
