INTRODUCTION

The Hillstar Development Kit is designed to support an easy integration of Microchip’s

MGC3130 3D Tracking and Gesture Controller into customer’s applications.

The three Hillstar PCBs 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 I2C to USB Bridge to evaluate customized

electrodes

•Use I2C to USB Bridge to parameterize and debug the MGC3130 application

circuitry in the customer’s design (in-circuit)

• Combine MGC3130 Unit and Electrodes to develop gesture-driven applications

for PC-based or embedded software environments

For in-circuit parameterization and debugging it is mandatory to control the MGC3130

via Aurea Control Software. For that purpose, the customer’s application should

provide an appropriate hardware or software interface.

INTEGRATION EXAMPLES

The following figures show typical hardware circuits for MGC3130 integration into a

customer’s application.

Figure 4-1 and Figure 4-2 show the control via I2C and an external PC. The Hillstar I2C

to USB Bridge acts as an I2C master, the application processor I2C should be:

• Switched off (I2C lines configured as high Z, refer to Figure 4-1)

• Switched to Slave or Listen mode or

• Disconnected (through an external switch, refer to Figure 4-2)

As an alternative, it is also possible to establish an USB connection between the appli-

cation processor and a PC without using an I2C to USB Bridge. Please refer to Figure

4-3.
