MAX7359 Evaluation Kit
Quick Start
Required Equipment
Before beginning, the following equipment is needed:
? User-supplied Windows 2000/XP/Vista-compatible
computer with a spare USB port
Note: Administrator privileges may be required when
first installing the device.
Note: In the following sections, software-related items
are identified by bolding. Text in bold refers to items
directly from the EV kit software. Text in bold and under -
lined refers to items from the Windows operating system.
Procedure
The MAX7359 EV kit is fully assembled and tested. Follow
the steps below to verify board operation.
1) Visit www.maxim-ic.com/evkitsoftware to download
the latest version of the EV kit software,
7359Rxx.ZIP. Save the EV kit software to a tempo-
rary folder and uncompress the ZIP file.
2) Install the EV kit software on your computer by
launching the 7359Rxx.MSI program inside the zip
file. The program files are copied and icons are
created in the Windows Start | Programs menu.
3) Ensure that the jumper settings are in the default
positions (see Table 1).
4) Connect the USB cable from the PC to the MAX7359
EV kit board. A Building Driver Database window
pops up in addition to a New Hardware Found
message when installing the USB driver for the first
time. If you do not see a window that is similar to the
one described above after 30s, remove the USB
cable from the board and reconnect it. Administrator
privileges are required to install the USB device dri-
ver on Windows 2000 and XP. Refer to Application
Note 3601: Troubleshooting Windows Plug-and-Play
and USB for Maxim Evaluation Kits if you have any
problems during this step.
5) Follow the directions of the Add New Hardware
Wizard to install the USB device driver. Choose the
Search for the best driver for your device option.
Specify the location of the device driver to be
C:\Program Files\Maxim MAX7359EVKIT (default
installation directory) using the Browse button.
During device driver installation, Windows XP shows
a warning message indicating that the device driver
Maxim uses does not contain a digital signature. This
is not an error condition. It is safe to proceed with the
installation.
6) Verify that the EV kit’s LED8 is lit, indicating that the
USB is connected and providing power.
7) Start the EV kit software by clicking its icon in the
Windows Start menu.
8) The software automatically connects to the board
after a few seconds.
9) Click the Initialize EV kit button to write the power-up
command and configure default settings for demon-
stration. This button writes to three registers:
Write(0x01 Configuration) = 0xAA; Write(0x02
Debounce) = 0x1F; and Write(0x03 Interrupt) = 0x2F.
10) On the EV kit board, press buttons in the
KEY0–KEY63 matrix. Verify that the key scan codes
are reported in the software’s history window after five
to six key-press events are queued, depending on
the debounce time and interrupt register settings. The
most recent scan code is identified in the Key Grid .
Detailed Description of Software
Connecting to Hardware
The MAX7359 EV kit software main window (Figure 1)
provides direct access to all registers and controls the
interrupt response. The software automatically search-
es for the MAX7359 EV kit hardware when launched.
Once the hardware is found and connected, the I 2 C
Device Address is shown in the upper-left corner.
Auto Read
The software automatically reads registers every 2s to
3s if the Auto Read all checkbox is checked.
