DM320016 DM320016 PCAP Touch Pad Development Kit with Gestures Product Brief INTRODUCTION DEMO MODE OPERATION Microchips Projected Capacitive Touch Pad This mode is intended for stand-alone use to Development Kit with Gestures showcases the high demonstrate the gestures and multi-touch capabilities performance and the flexible design of Microchips of Microchips MTCH6301 projected capacitive MTCH6301 projected capacitive touch controller. This controller. Toggle SW1 to ON and toggle SW2 to development kit also allows designers to test DEMO to use the Demo mode. The display will provide functionality, including multi-touch and gestures. visual feedback, as the touch pad area is activated with a finger. After connecting to a PC with the included PICkit Serial Analyzer (PKSA), developers may also interact with the MTCH6301 user parameters through the Note: Demo mode is for stand-alone use. The Projected Capacitive Configuration Utility (PCU), GUI PC software, GUI, will not connect to the program. For this program and more information about device while in this mode.

PICkit Serial Analyzer (Included): - Updated with PKSpCap406.hex FIGURE 2: MINI MAP USB mini Cable (Included) Male 6-pin Connector (Included) PCU, v 2.03 or later (available from the DM320016 device page). GETTING STARTED There are two switches mounted on the board: switch SW1 toggles the power and switch SW2 selects the Demo or Development mode. The included PKSA has 2 been programmed to function as a USB-to-I C communication bridge. The PKSA is necessary to communicate with the development software, PCU. 2014 Microchip Technology Inc.
