Getting StartedVisit the mTouch™ Sensing Solutions Design Center at http://www.microchip.com/mtouch for:
■ Software and documentation for the base touch device used in this demo, part # MTCH6301
■ Schematics, Gerbers, Drawings & BOM for the touch pad reference design
■ PCB sensor design guidelines ■ Confi guration Utility with auto tune capabilities
Frequently Asked QuestionsQ Does the Microchip PCAP code perform self or mutual
capacitance measurements?A Our code does both. We optimize speed and
performance by using a combination of both methods.
Q What patterns do we support?A This design supports a diamond pattern. Our code also
supports additional patterns that will be available on the mTouch Sensing Solutions design center.
Q What is the maximum channels supported?A 13 × 18 is the maximum channels supported with the
MTCH6301 device. This generally covers touch pad sizes from 1.5" to 4.3".
Q What cover lens overlay materials can this design support?
A This design uses a 1.5 mm acrylic overlay, but materials up to 3 mm plastic and 5 mm glass are possible.
