GENERAL DESCRIPTION

This user guide applies to the ADIS1650x IMU (Inertial

Measurement Units). The members of this family include the

ADIS16500, ADIS16505, and ADIS16507. Although only the

ADIS16505 is discussed within, this guide is applicable to all

members of the ADIS1650x family, as these devices differ

primarily performance levels and sensitivity ratings.

The ADIS16505 is a very small, high-performance. The

ADIS16505 features factory internal calibration, high

performance, and robust operation in dynamic and challenging

environments.

The ADIS16505 evaluation board, together with the EVAL-

ADIS2 are a compact, easy-to-use platform for evaluating all

features of the ADIS16505.

THE ADIS165505 BREAKOUT BOARD

Figure 2. ADIS16505-2/PCBZ

DESCRIPTION

Breakout boards provide a simple way to connect an existing

embedded processor platform to an ADIS16500, ADIS16505 or

ADIS16507 IMU. Each breakout board contains (1) IMU and a

simple interface connector, which provides access to all

necessary electrical connections with the IMU. Figure 2

provides a picture the ADIS16505-2/PCBZ breakout board,

which contains and ADIS16505-2BMLZ IMU model.

Table 1 provides a list of the model numbers for each breakout

board, along with the IMU model that is on each breakout

board.

DRAWING

Figure 3 provides a top-level view of the breakout board layout,

along with key physical attributes. The electrical interface (J1)

on each breakout board is a dual row, 2 mm pitch, 16-pin

interface. This supports standard ribbon cabling with 1 mm pitch.

PIN ASSIGNMENTS

Table 2 provides the J1 pin assignments which support direct

connection to an embedded processor board using standard

ribbon cables. Although each environment has its own

sensitivities (such as electromagnetic interference (EMI)), these

boards typically support reliable communication over ribbon

cables up to 20 cm in length.

EVALUATION USING THE EVAL-ADIS2 SYSTEM

Figure 5. EVAL-ADIS2 System Block Diagram

In addition to supporting quick prototype connections between the IMU and an embedded processing system, the breakout boards

connect directly to J1 on the EVAL-ADIS2 evaluation system. When used in conjunction with the IMU Evaluation Software for the EVAL-

ADISZ Platforms, the EVAL-ADIS2 provides a simple, functional test platform that allows users to configure and collect data from the

IMU models. Figure 5 and Figure 8

Important: Download and install USB drivers before connecting the EVAL-ADIS2 to the test computer.

USB DRIVER INSTALLATION

The following instructions cover the USB driver installation for

the EVAL-ADIS2, and is common to ADI IMU products.

1. Navigate to

ftp://ftp.analog.com/pub/IMU/IMU_FTP_Directory.htm.

2. Locate and click on the link called SDPDrivers.zip under

the heading of EVAL-ADIS2 USB drivers.

3. After downloading the EVAL-ADIS USB Driver file,

extract the SDPDrivers.exe file from the zip file and double

click on the EXE to start the process. When the setup

wizard opens, click on Next to start the installation process:

4. Click on Next to accept the default driver location.

5. The user will see at least two progress bars like this:

Rev. PR.C | Page 6 of 11

6. Click on Install to continue with the installation if this

message appears during the process:

7. Click Finish to complete the process.

DOWNLOADING THE EVALUATION SOFTWARE

The evaluation software for the ADIS16505 can be downloaded

from the ADI IMU ftp site

1. Navigate to the ftp site by clicking here:

ftp://ftp.analog.com/pub/IMU/IMU_FTP_Directory.htm

2. Click on “IMU Evaluation 1.18.xx” where “xx” is the latest

version posted on the FTP site.

After the EXE file downloads, place it in a convenient location

on the host PC, but don’t run it until the evaluation board is

connected to the PC.

Note: If the user runs the software before connecting the

evaluation board, the user will see the following pop-up

windows and errors:

If this occurs, the user should exit out of the software, and

proceed to the “EVAL-ADIS2 Physical Connections” section of

this user guide and ensure that the evaluation board is properly

connected and powered prior to running the evaluation

software.

EVAL-ADIS2 PHYSICAL CONNECTIONS

Figure 8 illustrates the physical connection between the

ADIS16505-2/PCBZ and an EVAL-ADIS2Z evaluation system.

Connecting the Evaluation Boards

1. Ensure that Jumper JP1 (See “DUT Supply Selection” in

Figure 6) is straddling the left “+3.3V REG” pin and the

center pin, assuming the EVAL-ADIS2 board is oriented as

shown in Figure 6.

Note: If the user wishes to use an external power supply,

move the JP1 jumper so that it straddles the center and

lower pin and connect the external supply to Connector J3.

GND is the left pin and VDD (+3.3 V) is the right pin.

See Figure 7 for an illustration.

2. Connect the ribbon cable between the EVAL-ADIS2 and

ADIS16505 evaluation board.

3. Connect the EVAL-ADIS2 USB cable to the PC and verify

that LED1 and LED2 are illuminated on the EVAL-ADIS2

board.

EVALUATION SOFTWARE

RUNNING THE EVALUATION SOFTWARE

1. Ensure the that USB Driver is properly installed as

described in the “USB Driver Installation” section of this

user’s guide.

2. Ensure that the evaluation board is properly connected as

described in the “EVAL-ADIS2 Physical Connections”

section of this user’s guide.

3. Double-click on the ADIS16505 evaluation software EXE

file. The user should click the “Run” button if this pop-up

window appears:

4. The EVAL-ADIS main window appears

5. On the Devices Menu, select the correct IMU model.

6. Click on the “READ” button to read the IMU registers in

real-time. If the EVAL-ADIS2 is correctly connected, and

all the drivers and software are correctly installed, the user

should see the following, if the IMU is at rest and lying

face-up on a flat surface:

Note that the gyroscopes read zero rotation, the x- and y-

axis accelerometers read 0 g, and the z-axis reads 1 g.

ADIS1650x/PCBZ User Guide UG-ADIS1650x

Rev. PR.C | Page 9 of 11

7. Movement of the IMU is recorded and displayed in real

time:

8. The user can change register settings by clicking on the

“Register Access” menu. In this example, the decimation

rate is being changed from 0x00 to 0x07.

9. Logging the IMU readings is a common task using the

EVAL-ADIS2 and clicking on the Data Capture menu

brings up the data capture window. This window allows the

user to choose which settings to log. Note that if a

decimation rate of 0 (no averaging) is used, the user will

need to select 16-bit gyro and accelerometer values (not

32-bit) to have enough time to transfer all data in one data

capture interval. However, this does not limit the accuracy

of the IMU data, as the lower 16-bits are only significant

when averaging or filtering is enabled.

Rev. PR.C | Page 21 of 21

TROUBLESHOOTING

RUNNING THE SOFTWARE WITHOUT AN EVAL-

ADIS2 EVALUATION BOARD ATTACHED

The user will see the following screens if the evaluation software

is run without the EVAL-ADIS2 connected:

In this case, the user should exit out of the software, and

proceed to the “EVAL-ADIS2 Physical Connections” section of

this user guide and ensure that the evaluation board is properly

connected and powered prior to running the evaluation

software.

DEVICE BLACKLISTED

The most common cause of this error is attempting to read the

registers of the IMU while the EVAL-ADIS2 evaluation board is

disconnected from the PC after having previously been

successfully connected. Communication can be restored by

reconnecting the EVAL-ADIS2 to the PC.

LOG FILE ERROR

This error occurs if the filename specified for the data log file

already exists. The user should either rename the existing file or

choose a different filename for the new log file.
