CAPSENSE™ Middleware Library

Overview

CAPSENSE™ is CYPRESS™ capacitive sensing solution from Infineon Technologies AG. Capacitive sensing can be used in a variety of applications and products where conventional mechanical buttons can be replaced with sleek human interfaces to transform the way users interact with electronic systems. These include home appliances, automotive, IoT, and industrial applications. CAPSENSE™ supports multiple interfaces (widgets) using the Self-Capacitance (CSD), Mutual-Capacitance (CSX), and Inductive sensing (ISX) sensing methods with robust performance.

CAPSENSE™ has become a popular technology to replace conventional mechanical- and optical-based user interfaces. There are fewer parts involved, which saves cost and increases the reliability with no wear-and-tear. The main advantages of CAPSENSE™ compared with other solutions are: robust performance in harsh environmental conditions and rejection of a wide range of external noise sources.

Use CAPSENSE™ for:

  • Touch and gesture detection for various interfaces
  • Proximity detection for innovative user experiences and low-power optimization
  • Contactless liquid-level sensing in a variety of applications
  • Touch-free operations in hazardous materials

Features

  • Offers best-in-class signal-to-noise ratio (SNR)
  • Supports the Self-Capacitance (CSD), Mutual-Capacitance (CSX), and Inductive (ISX) sensing methods
  • Features smart sensing algorithm 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 CAPSENSE™ Tuner for real-time tuning, testing, and debugging
  • Provides superior immunity against external noise and low-radiated emission
  • Offers best-in-class liquid tolerance
  • Supports one-finger and two-finger gestures

Quick start

The ModusToolbox™ CAPSENSE™ Configurator User Guide instructs step-by-step
how to configure and launch the CAPSENSE™ Configurator in ModusToolbox™. The CAPSENSE™ Configurator can be launched in the ModusToolbox™ IDE from the CSD, MSC or MSCLP personality and as a stand-alone tool. Refer to ModusToolbox™ Software Environment, Quick Start Guide, Documentation, and Videos.

Use code examples to quickly start the CAPSENSE™ Configurator. Infineon Technologies AG continuously extends their portfolio of code examples at the Infineon Technologies and at the Infineon Technologies GitHub.
