New maXTouch® button on Display™
CHANDLER, Ariz., June 30, 2022 (GLOBE NEWSWIRE) — Many automotive and industrial touch HMI designers seek to merge the benefits of a mechanical rotary encoder input with the flexibility of modern multi-touch displays. Microchip Technology Inc. (MCHP) announce today the maXTouch® Knob on Display™ (KoD™) Controller as the first family of automotive-grade touchscreen controllers to natively support sensing and reporting of capacitive rotary encoders, as well as mechanical switches above a touchscreen. Unlike traditional mechanical rotary encoders, this new technology allows the button to be mounted directly on the screen without opening in the panel or customizing the touch pattern, increasing design flexibility and system cost savings.
KoD technology eliminates the need for custom touch sensor designs, giving designers the ability to easily implement a different button count, shape, and position to accommodate a variety of end-user products. Custom configurations are adjustable without modifying the embedded firmware of the maXTouch KoD Touch Controller, allowing for a faster and more flexible development cycle. The maXTouch KoD controller allows designers to retain the convenience of a rotary encoder input device but combine it with modern, innovative interior design using smart surfaces and multi-touch screens.
An additional benefit that designers can expect to discover is the ease of building a sealed human-machine interface (HMI) module, which is becoming increasingly popular for home appliances and industrial applications. Using a button on a screen will also increase end-user safety, for example, they won’t need to look at the screen while driving to adjust their sound or air conditioning.
“Modern user interfaces typically use multi-touch screens, doing away with mechanical keys for cutting-edge designs. Yet functions like temperature or audio volume are still better controlled by a rotary encoder,” said Clayton Pillion, vice -President of the Human-Machine Interface Business Unit at Microchip Technology “The new maXTouch KoD technology offers the benefits of both worlds by providing support for a capacitive rotary encoder with a family of turnkey touch controllers and a complete suite of dedicated tools for rapid implementation.”
With the launch of the maXTouch KoD family, Microchip is offering two variants to allow customers the design freedom and flexibility to choose how they will implement the capacitive rotary encoder. The KD variant allows customers to choose their button design partner and create their own solution using a reference design jointly developed with BNL Bearings, providing the ability to fully customize the design for specific applications.
Additional MK variant supports Magic Knob™ developed by Panasonic Industry Co., Ltd. While maintaining the flexibility to be mounted on standard touch sensor models, the Microchip Panasonic Magic Knob (MPMK) solution offers a high level of customization for rotation and deep haptic feedback, as well as the high choice of material of coating.
Microchip provides a full suite of hardware and software development tools to shorten the development cycle with a capacitive rotary knob.
