8) On the Data Conversion tab sheet (Figure 1),
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.
press the Convert Start button in the Continuous
Conversion group box to view the ambient and prox-
