DS9090K 1-Wire Memory Evaluation Kit
Connect the evaluation board to the PC with the supplied RJ-11 to RJ-11 cable. To do this, one end of the cable
should be plugged into the evaluation board and the other end into the DS9097U-E25.
Software Installation
Install the latest 1-Wire Drivers package (http://www.ibutton.com/software/tmex/). These drivers require a Win32
platform such as Windows XP, 2000, ME, 98, or 95. The installation program will prompt the user to select a default
1-Wire network adapter. Choose the DS9097U tab and the COM port number correlating to that being used
(usually 1, 2, or 3). This also can be chosen after installation by running the "Default 1-Wire Net" program that gets
installed with the drivers. For Linux and other operating system platforms, support for the DS9097U-E25 1-Wire
adapter can be installed through RXTX (or other equivalent software packages compliant with the Java
Communications API). See the OneWireViewer page for pre-built RXTX libraries for Linux.
Click on "Start->Programs->1-Wire Drivers". Then click on the OneWireViewer icon. This will bring up a webpage
with information on how to install the OneWireViewer.
Run the OneWireViewer. Once running the 64-bit ROM ID value of the 1-Wire chip should be displayed on your PC
in the Viewer. Select the address of the chip and other tabs should be made available that contain functionality to
exercise the chip (i.e., read and write data, files, etc.).
KIT OPERATION
Connect the evaluation board to the PC, making sure it contains the 1-Wire memory device of choice properly
oriented and inserted. See "Hardware Installation" above for help.
Run the OneWireViewer. If you have any difficulty, see the "Troubleshooting Guide" at the bottom of this page.
Another helpful resource is the OneWireViewer User’s Guide. It can be downloaded from the following link:
http://www.maxim-ic.com/appnotes.cfm/appnote_number/3358.
The OneWireViewer contains a "Device List" window located on the left-hand side of the main screen. It shows a
list of the different 1-Wire devices it finds connected to the DS9097U-E25. The 1-Wire device type inserted into the
socket or header of the eval board should be shown in “Device List” window along with the 64-bit ROM ID lasered
into the device. The screenshot below shows the DS2433 in the "Device List" window, along with its 64-bit ROM ID
value of "890000002548B023". From the "Device List" window select the part by clicking on it.
Read from or write to the 1-Wire memory: Once the 1-Wire device has been selected, the right-hand side of the
main OneWireViewer screen will be populated with different tabs. There will be at least three tabs for each device
contained in the DS9090K kit: Description, Memory, and File. Click on the "Memory" tab. It will bring up the
"Memory Viewer" shown in the screenshot below. You will have the choice of reading/writing any of the memory
banks listed in the "Banks" section of the "Memory Viewer". Select the "Main Memory" bank It should bring up the
"Info" and "Contents" similar to that of the screenshot below. The "Info" section of the "Memory Viewer" shows the
different attributes of the memory bank being exercised. The "Contents" section shows the actual contents of the
memory. To edit the 1-Wire memory, just click in the appropriate box (labeled with Page 0, Page 1, Page 2, etc)
and start typing in the appropriate hexadecimal characters.
When finished editing, click on the "Commit Changes" button to write the changes to memory. To have the
OneWireViewer re-read the contents of the 1-Wire memory, click on the "Refresh" button.
