Fujitsu Semiconductor Europe has introduced high-performance capacitive touch functionality for its FM3 Family of ARM Cortex-M3 based microcontrollers.
The FM3touch library delivers the easy integration of capacitive touch functionality in state-of-the-art Human-Machine-Interfaces (HMI) for a wide range of industrial, home appliance and medical applications.
The new capacitive touch functionality combines high sensitivity with low system load, and supports developers in creating flexible and designed HMI applications.
FM3touch uses an ADC-based, patent-pending capacitive sensing algorithm to reach the sensitivity of only a few femto-Farad, using one pin-per-touch input channel without the need for external components.
A graphical PC tool can be used to monitor the touch data and to facilitate the setup of different parameters.
