GENERAL DESCRIPTION

The iSensor® family of products provides a serial peripheral inter-

face (SPI) for data communications. The SPI interface and a

well-calibrated cluster of sensors enable quick integration into

systems that employ embedded processor systems. For users who

are familiar with embedded processors, integrating the iSensor

device with a familiar processor system enables development

with familiar software tools, provides more flexibility, and enables

more design reuse after the initial sensor evaluation is complete.

For users who are unfamiliar with embedded processors and

their development tools, the EVAL-ADIS system provides a

simple PC-based tool for getting started with iSensor products.

The EVAL-ADIS circuit board provides tapped holes (M2 ×

0.4 mm), and the kit includes an assortment of M2 × 0.4 mm

machine screws for a simple device under test (DUT) attach-

ment. The location of the mounting holes facilitates easy

electrical connection with the mating connectors (J1 or J4

on the EVAL-ADIS).

The power management system provides jumper selection for

three device under test (DUT) power options: 5 V (USB), 3.3 V,

and an external power option. The 5 V option provides access

to the USB’s 5 V supply voltage for the DUT, and the 3.3 V

option uses a linear regulator, 400 µF of bulk capacitance, and a

soft start circuit to manage transient currents on the USB port.

The evaluation software packages, which support operation

with the EVAL-ADIS, typically offer three modes of operation:

demonstration, register access, and data capture. In most cases, the

demonstration mode will be a simple waveform recorder function,

which provides a simple visual response to sensor motion. The

waveform recorder is useful in concept demonstrations or

functional verification of units. Individual register read and

write cycles are available in the Register Access window. PC

data acquisition is available using the Data Capture window,

which provides various control inputs, including data register

selection, data file format, and data storage location. In data

capture mode, the EVAL-ADIS reads and stores data from each

selected register every time that the sensor’s data-ready signal

pulses. This synchronous capture mode supports the ADIS16488

(10 registers, 16-bits wide, 2.46 kSPS)

The EVAL-ADIS kit includes a USB mini cable for quick

connection to a PC. The IMU evaluation software package

supports operation on Windows® XP, Windows Vista, and

Windows 7 (32-bit and 64-bit) PC systems.
