The MAX9635 EV kit software GUI (Figure 1) is a
Windows program that provides a convenient means
to control the MAX9635. The EV kit software accurately
reads the device’s digital output and displays the lux
reading of ambient light. The software has an option
to extend the resolution and dynamic range of lux
measurements. The software also sets the upper and
lower lux threshold limits, configures the interrupt
functionality, and configures other modes of device.
Refer to the Register and Bit Descriptions section in the
MAX9635 IC data sheet for further details.
The Data Log checkbox enables the user to log the lux
readings data.
