Microchip’s MGC3X30 are 3D gesture recognition and motion tracking controller chips based on Microchip’s patented GestIC® technology. They enable usercommand input with natural hand and finger movements. Applying the principles of electrical nearfield sensing, the MGC3X30 contain all the building blocks to develop robust 3D gesture input sensing systems. Implemented as a low-power mixed-signal configurable controller, they provide a large set of smart functional features with integrated signal driver,a frequency adaptive input path for automatic noise suppression and a digital signal processing unit. Microchip’s on-chip Colibri Suite obsoletes processing needs at the host, reduces system power consumption resulting in low software development efforts for short time-to-market success. The MGC3XXX family represents a unique solution that provides gesture information of the human hand in real time. Dedicated chip family members add position data, touch or multi touch information to the free space gesture sensing.
The MGC3XXX allow the realization of a new generation of user interfaces across various industry markets.

Woodstar開發(fā)板
The Woodstar Development Kit is designed to support an easy integration of Microchip’s MGC3030 3D Gesture Controller into the customer’s applications. It provides MGC3030 system setup, related hardware and software references:
• Aurea Software Package with the Aurea Graphical User Interface and GestIC Library
• MGC3030/3130 Software Development Kit (SDK)
• MGC3030/3130 PIC18 Host Reference code
With the help of these tools, the design-in process can be easily performed in five steps:
1. Feature Definition
2. Electrode Design
3. MGC3030 Parameterization
4. Host Application Programming
5. Verification
Woodstar hardware builds a complete MGC3030 reference system consisting of three
individual PCBs:
• MGC3030 Unit
• I2C™ to USB Bridge
• Reference Electrode with a 95x60 mm sensitive area
It can be plugged to a PC via a USB cable and used for evaluation of the MGC3030
chip and the GestIC technology. During the customer’s design-in process the individual
boards can be combined according to the customer’s needs.
Three examples are given below:
• Combine the MGC3030 unit and the I2C to USB bridge to evaluate customized electrodes
• Use the I2C to USB bridge to parameterize and debug the MGC3030 application circuitry in the customer’s design
• Combine the MGC3030 unit and electrodes to develop gesture-driven applications for PC-based or embedded software environments
Woodstar開發(fā)板包括:
• MGC3030 Module
• I2C to USB Bridge Module
• Reference Electrode (95x60 mm sensitive area)
• USB Cable for PC Connection
