MAX44000 Evaluation System
Evaluates: MAX44000
General Description
The MAX44000 evaluation system (EV system) includes
one MAX44000 evaluation kit (EV kit) and one MAX44000
daughter board. The EV kit is a fully assembled and test-
ed PCB that evaluates the MAX44000 ambient light and
proximity sensor. The EV system also includes Windows
XP
M
-, Windows Vista
M
-, and Windows
M
7-compatible
software that provides a simple graphical user interface
(GUI) for exercising the features of the device. The EV
kit comes installed with a MAX44000GDT+ in a 6-pin
OTDFN package with an exposed pad.
The daughter board is an external device-under-test
module that also comes with a MAX44000GDT+ installed.
The daughter board can be connected to and controlled
by the EV kit. The user can also evaluate the device by
connecting a user-supplied controller to the daughter
board.

MAX44000 Evaluation System
Evaluates: MAX44000
Quick Start
• MAX44000 EV kit (USB cable included)
Required Equipment
8) On the
Data Conversion
tab sheet (Figure 1),
press the
Convert Start
button in the
Continuous
Conversion
group box to view the ambient and prox-
imity ADC data on the graphs.
• Windows XP, Windows Vista, or Windows 7 PC with a
spare USB port
Note:
In the following sections, software-related items are
identified by bolding. Text in
bold
refers to items directly
from the EV system software. Text in
bold and underline
refers to items from the Windows operating system.
The 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, 44000Rxx.ZIP.
Save the EV kit software to a temporary folder and
uncompress the ZIP file.
2) Install the EV kit software and USB driver on your com-
puter by running the INSTALL.EXE program inside
the temporary folder. The program files are copied to
your PC and icons are created in the Windows
Start
| Programs
menu. During software installation, some
versions of Windows may show a warning message
indicating that this software is from an unknown pub-
lisher. This is not an error condition and it is safe to
proceed with installation. Administrator privileges are
required to install the USB device driver on Windows.
3) Verify that all jumpers (JU6, JU7, JU8, and JU10–
JU17) are in their default positions, as shown in
Table 1.
4) Connect the USB cable from the PC to the EV kit
board. A Windows message appears when connect-
ing the EV kit board to the PC for the first time. Each
version of Windows has a slightly different message.
If you see a Windows message stating
ready to use,
then proceed to the next step. Otherwise, open the
USB_Driver_Help_200.PDF document in the Windows
Start | Programs
menu to verify that the USB driver
was installed successfully.
5) Start the EV kit software by opening its icon in the
Start | Programs
menu. The EV kit software main
window appears, as shown in Figure 1.
6) On the
Proximity Sensor Configuration
tab sheet
(Figure 2), in the
Transmit Configuration
group box,
use the
LED Drive Current (DRV[3:0])
track bar to
set the IR LED current to 10mA. Press the adjacent
Set
button.
7) Select
ALS and Prox interleaved
from the
Operation
Mode
drop-down list.
Detailed Description of Software
The MAX44000 EV kit software (Figure 1) has all the
functions to configure the MAX44000 and receive the
ADC data from the device. The software contains an
I2C
Interface
group box, a
Status
group box, and four tab
sheets to configure the device and receive the ambient
and proximity data from the device.
In the
I2C Interface
group box, enter the register address
in the
Reg Address
edit box and press the
Read
button
to read the register. The returned value is shown in the
Data
edit box. To write a data into a register, enter the
register address in the
Reg Address
edit box, enter the
data into the
Data
edit box, and press the
Write
button.
Use the
Operating Mode
drop-down list to select one
of the six operating modes. The operating modes are:
Shutdown, Standard ALS, ALS Green channel only,
ALS Red channel only, ALS and Prox interleaved,
and
Prox only.
The
Single Conversion
group box on the
Data
Conversion
tab sheet displays the
Ambient
and
Proximity
ADC values for a single sample. Press the
Convert
button to update the values in the
Ambient
and
Proximity
group boxes. Check the
Auto Convert
checkbox to automatically and repeatedly do the ADC
conversion and update the values in the
Ambient
and
Proximity
group boxes. Check the
Save to File
check-
box to save the received data to a file.
Press the
Convert Start
button in the
Continuous
Conversion
group box to continuously read the
ambient and proximity ADC data from the device and plot
the data on the
Ambient Sensor
and
Proximity Sensor
graphs. The rate that the controller reads the data from
the device is selected from the
Displaying Rate
drop-
down list. The last ambient and proximity samples are
displayed in the
Last ALS/PROX Reading
group box in
the
Status
group box. Check the
Save to File
checkbox
to save the received data to a file.
The white LED (WLED) on the EV kit simulates the back-
light of a cell phone. The software adjusts the brightness
of the WLED according to the ambient measurement.
