Microchip introduces mTouch™ inductive touch sensing solution

23 DECEMBER 2008

Microchip announces new mTouch™ Inductive Touch-Sensing Technology, as an addition to its capacitive touch-sensing solutions. Inductive touch sensing’s fundamental operating principles enable it to work through a front panel such as plastic, stainless steel or aluminium. The technology also works through gloves and on surfaces that contain liquids.
Microchip enables designers to integrate inductive touch-sensing functionality within existing application code in a single standard 8-, 16- or 32-bit PIC® microcontroller (MCU) or 16-bit dsPIC® Digital Signal Controller (DSC). Touch sensing also enables a completely sealed and modern-looking design. Applications for inductive touch-sensing include stainless steel front panels for appliances, robust industrial equipment and automotive applications because of the ability to reduce accidental touch triggers. Implementation details for Microchip’s inductive touch sensing solutions are available now by free download from www.microchip.com/mtouch. Items available for download include user manual with quick-start guide for building an inductive touch-sensing application and application notes covering hardware and software design practices, with example implementations for inductive touch-sensing solutions, such as inductive touch mechanical design, inductive touch hardware and inductive touch software. Also available for download are graphical user interface software tools for analysis of designs, utilising Microchip’s PICkit™ Serial Analyzer development tool, source code for a variety of sensing routines and frequently asked questions. Microchip continues to make it easy, inexpensive and royalty-free for engineers to implement touch-sensing interfaces into their designs. With the addition of inductive touch technology, Microchip now gives designers even more flexibility to choose the best touch-sensing technology for their application.
