AN56691 - CapSense® Express™ - Creating Reference Designs with 1CS/2CS Button Devices
CapSense Express is a family of high-performance, fixedfunction devices that provides a robust solution for simple designs (involving few buttons, slider, LEDs and general purpose I/Os). CapSense Express controllers support two capacitive sensing (CapSense) buttons and two generalpurpose outputs in CY8C20121 and one CapSense button and one general-purpose output in CY8C20111. The host controller can configure these as I2C slave devices and read the sensor information in real time. A software tool is also provided for achieving optimal performance in real time using a GUI. These are plug and play devices with factory default settings. The 1B/2B devices achieve CapSense functionality without requiring any external components. The ease of use of these devices leads to reduced cost and less time to market the solution.
