3D GestIC SENSING DEVELOPMENT KIT USER’S GUIDEChapter 1. Overview
1.1 INTRODUCTION
Microchip’s DV102014 development kit builds a complete reference system for evaluation and design of 2D multi-touch and 3D gesture human-machine interfaces. This combination enables user command input with multi-touch detection on surfaces as well as natural hand movements in free space.
The kit content is described below:
• 2D/3D Electronics Board with Microchip parts:
- MTCH6303 2D PCAP (Projected Capacitive) controller
- MGC3130 3D GestIC® controller
- MTCH652 high-voltage driver
• 2D/3D Sensor Module
- 8" PCAP touch screen
- 3D Printed Circuit Board (PCB) electrodes
• Micro-USB cable
1.2 WORKING PRINCIPLE
This combined 2D/3D technology solution uses Microchip’s MTCH6303 2D PCAP Controller, the MGC3130 3D GestIC Controller, and the MTCH652 High-Voltage Driver. The system works in Time-Multiplex mode that dynamically detects 2D and 3D operations.

3D GestIC SENSING DEVELOPMENT KIT USER’S GUIDEChapter 2. Getting Started
Follow the following steps to get started:
1. Download and install the 2D/3D design-in utility AUREA 2.x to your Windows® 7/8/10 PC from www.microchip.com/DV102014.
2. Connect the micro-USB cable to the 2D/3D Electronics Board and your PC, as shown in Figure 2-1.
FIGURE 2-1: BACKSIDE VIEW
3. Carefully turn the assembled hardware over and lay on a flat table surface. The six stand-offs support the hardware, creating a flat level touch surface.
FIGURE 2-2: TOPSIDE VIEW

DV102014 Projected Capacitive Multi-Touch with 3D GestIC® Sensing Development Kit User’s Guide
2.1 SETUP
1. Launch the Aurea 2.x Software Utility, (note the green check on the USB symbol
to indicate a successful connection ).
2. Navigate to the Setup tab and select 3D Parameterization (see Figure 2-3).
FIGURE 2-3: SETUP TAB
DS40001834A-page 16 2016 Microchip Technology Inc.
Getting Started
3. Select Start Autoparameterization (this step automatically optimizes the settings for the development kit by pushing the Autoparameterization button).

7. Navigate to the Colibri Suite tab to demonstrate 2D and 3D capabilities, as briefly described below. See the utility documentation for a more detailed intro-duction to the various built-in features.
FIGURE 2-7: COLIBRI SUITE TAB
DS40001834A-page 20 2016 Microchip Technology Inc.
Getting Started
8. The Colibri Suite tab allows the user to turn on/off the 2D and 3D gesture reporting. These controls are found on the left side of the program and help simulate the conditions and features of the user’s application. Gestures that are performed by the user are seen in the Gesture output window in the bottom right corner.

11. Use your hand to swipe left to right over the 2D/3D sensor module. Verify that the red gesture arrows follow your movements in the bottom right Gestures window. The hand distance should be ~10 cm (up to 20 cm) above the sensor. Always check that the desired gesture is actually activated in the 2D and/or 3D overview on the left side of the screen.
