About

CAPSENSE? ADC v3.0: Optimal Capacitive Sensing

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? ADC 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? ADC 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?) ADC
  • 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
  • Supports ADC function with:
    • ? ?Selectable 8- or 10-bit resolution
    • ? ?Sample rates of up to 11.6 ksps with 10-bit resolution
    • ? ?Input measurement range from VSSA to VDDA on any GPIO pin
Limitations of PSOC? 4 Capacitive Sensing (CAPSENSE?) ADC

This component supports all CAPSENSE?-enabled devices in the PSOC? 4 family of devices, including: Fourth generation CAPSENSE?: PSOC? 4000S, PSOC? 4100S, and PSOC? Analog Coprocessor.

However, some features are restricted in specific devices:

  • The Export Register Map feature will be available in the next component version.
  • The CSD2x functionality will be available in the next version of the component.
  • The CAPSENSE? Tuner does not support ADC functionality. This feature will be added in a future component version.
  • The IDAC sensing configuration feature will be available in the next component version.
