Chapter 1. Overview
1.1 INTRODUCTION
The MGC3130 is the first product based on Microchip’s GestIC
®
technology. It is
developed as a mixed-signal controller. The MGC3130 has one transmit and five very
sensitive receive channels that are capable to detect changes of a transmitted electrical
field (E-field) corresponding to capacitive changes in the femtofarad (1 fF = 10
-15
F)
range.
In order to transmit and receive an electrical field, electrodes have to be connected to
the transmitting and receiving channels of the MGC3130 controller. The spatial
arrangement of the electrodes allows the chip to determine the center of gravity of the
electric field distortion, and thus position tracking and gesture recognition of a user’s
hand in the detection space.
1.2 HILLSTAR CONCEPT AND DELIVERABLES
The Hillstar Development Kit is designed to support an easy integration of Microchip’s
MGC3130 3D Tracking and Gesture Controller into customer’s applications. It provides
MGC3130 system setup, related hardware and software references.
With the MGC3130 Software Package, including Aurea Graphical User Interface and
GestIC Library, the MGC3130 Software Development Kit (SDK) and PIC18 Host
Reference code, design-in is easy in five steps:
1. Feature Definition
2. Electrode Design
3. MGC3130 Parameterization
4. Host Application Programming
5. Verification
Hillstar hardware builds a complete MGC3130 reference system consisting of three
individual PCBs:
MGC3130 Unit
•I
2
C™ to USB Bridge
Reference Electrode with a 95x60 mm sensitive area
It can be plugged to a PC via USB cable and used for evaluation of MGC3130 chip and
GestIC technology. During the customer’s design-in process the individual boards can
be combined according to the customers need.
Three examples are given below:
Combine MGC3130 Unit and I
2
C to USB Bridge to evaluate customized
electrodes
•Use I
2
C to USB Bridge to parameterize and debug the MGC3130 application
circuitry in the customer’s design
Combine MGC3130 Unit and Electrodes to develop gesture-driven applications
for PC based or embedded software environments
