About

CAPSENSE?: Advanced capacitive sensing features

CAPSENSE? is a capacitive sensing solution. It supports multiple widgets (group of sensors used to form an interface) using both CSX and CSD sensing methods.

The CAPSENSE? component solution includes a configuration wizard to create and configure CAPSENSE? Widgets, APIs to control the component from application firmware, and a CAPSENSE? Tuner application for tuning, testing, and debugging.

Note The CAPSENSE? P4 v3.0 component (and any version that follows) is not backward compatible with CAPSENSE?_CSD_P4 v2.40 or older. If you wish to migrate your design to the new CAPSENSE? P4 v3.0 component, refer to the “Migration Guide” section in the datasheet for details on how to manually transition the design.

Features of PSOC? 4 Capacitive Sensing (CAPSENSE?)
  • Offers best-in-class signal-to-noise ratio (SNR)
  • Supports Self-Capacitance (CSD) and Mutual-Capacitance (CSX) sensing methods
  • Features SmartSense? auto-tuning technology for CSD sensing to avoid complex manual tuning process
  • Supports various Widgets, such as Buttons, Matrix Buttons, Sliders, Touchpads, and Proximity Sensors
  • Provides ultra-low power consumption and liquid tolerant capacitive sensing technology
  • Contains integrated graphical tuner for manual tuning, testing, and debugging
Limitations

This component supports all CAPSENSE? enabled devices in the PSOC? 4 family of devices, including:

  • Third generation CAPSENSE?: PSOC? 4000, PSOC? 4100, PSOC? 4200, PSOC? 4100M, PSOC? 4200M, PSOC? 4200L, PSoC? 4100 BLE, PSOC? 4200 BLE, and PRoC BLE
  • Fourth generation CAPSENSE?: PSOC? 4000S, PSOC? 4100S, and PSOC? Analog Coprocessor

However, some features are restricted in specific devices:

  • The second hardware CSD block is not supported for PSOC? 4100M / PSOC? 4200M devices.
  • CSX Sensing mode is not supported for PSOC? 4100 devices.
  • The CSD2x functionality will be available in the next version of the component.
  • The Export Register Map feature will be available in the next component version.
  • The sourcing IDAC sensing configuration is not available for fourth generation CAPSENSE? devices and will be available in the next version of the component.
