The download begins and is automatically verified by the
downloader.
2.
If the downloading process fails, which is indicated in the
Monitor Status
box (see Figure 13), attempt the download
again by clicking
Start
and then pressing the switch
combination in Step 1. It may take a few attempts to
reprogram the board successfully. Ensure that the cables
and boards are stationary during programming to prevent
loose connections.
3.
After the download has completed successfully, click
Run
(
as shown in Figure 13) to reset the ISEB and to begin
running the new firmware. When this step is complete, the
board is updated correctly.
Updating the firmware may require that a new evaluation GUI
be obtained. If the firmware on the CD is used to flash the ISEB,
the evaluation GUI on the corresponding CD is sufficient. If the
firmware used is obtained from the Analog Devices website
(
http://www.analog.com/iseb
), the most recent version of the
evaluation GUI, which is also located on the Analog Devices
website, should be used.
Installing the ADXRS450/ADXRS453 Software
Evaluation GUI
With all the drivers and firmware in place, follow these steps to
install the evaluation GUI.
1.
Browse to
/ADXRS450/ADXRS450 Eval Software
Installation/
on the CD and double-click on
ADXRS450
Install.exe
. Depending on your Windows settings, you may
be prompted to allow the program access to your computer.
The window that opens will be similar to Figure 3.
2.
Follow the on-screen instructions to install the GUI.
The installer will place the GUI in your
Start Menu
under
Analog Devices – Inertial Sensor Eval
. If you install or
have installed other inertial sensor evaluation GUIs, they
will also be in this folder, identified by the corresponding
part number.
HARDWARE CONFIGURATION
To configure the hardware, follow these steps:
1.
If the hardware is not already connected, plug the USB A to
Mini-B cable into the PC.
2.
Connect the ISEB to the USB cable.
3.
If prompted to install the device, see the Downloading All
Files to a PC section for details on how to install and select
the correct driver.
4.
Ensure that the jumpers on the
ADXRS450
/
ADXRS453
satellite are in their default configuration, as shown in
Figure 16. This sets up the board to use the on-board boost
converter to generate the required high voltage supply for
the device. For more information on using alternate high
voltage supplies, see the
ADXRS450
and
ADXRS453
data
sheets and the Alternate External High Voltage Supply
section of this guide.
