Touch sensing dev kit

News

22 June 2011 News

Dataweek is offering readers the chance to win a Microchip capacitive touch development kit.

Projected capacitive touch sensing extends resistive and existing capacitive touch sensing technology to include multi-touch and gesture sensing, enabling users to implement robust glass-front user interfaces that simplify user interaction. Typical applications include global positioning systems, thermostats, mobile handheld units and other devices that use smaller displays with a finger input.

The mTouch Projected Capacitive Development Kit (DM160211) provides a fully functioning projected capacitive touch system. The kit is also a sophisticated development platform to facilitate implementation of projected capacitive touch screen user interfaces. Preprogrammed firmware provided with this kit supports multitouch with sensors ranging from 1x1 to 13x11 XY electrode patterns. The source code is available royalty-free from www.microchip.com/mtouch for use on Microchip PIC MCUs.

The kit includes a 3,5” sensor mounted on a sensor board, a projected capacitive board with the PIC16F707 MCU and fully functional firmware. The PIC16F707 features two 16-channel capacitive sensing modules (CSMs) that can run in parallel for increased sampling speed, and operates from a wide input voltage range of 1,8–5,5 V, with a typical projected capacitive sensor application operating current of 1,5 mA at 5 V. The open source code supports sensors with up to 32 channels and the kit includes a graphical user interface tool that enables easy parameter adjustment.

For your chance to win one of these development kits, visit www.microchip-comps.com/dw-procap and complete the online entry form.

Competition entries close 30 June 2011.
