Theory of Operation
Navigation Technology
The heart of the ADNS-3040 navigation sensor is a CMOS image
array. An LED and an optical system illuminate the surface that
the ADNS-3040 is navigating on. The texture of the surface
casts bright and dark spots forming distinct images as the
sensor is moved across the surface. A Digital Signal Processing
(DSP) engine and its built-in algorithm evaluate these images
and determine the magnitude and direction of the movement.

The motion data is made available in the delta_X and delta_Y
registers for the system controller to retrieve. An extensive
power saving topology is implemented within the ADNS-3040
navigation engine. A Motion pin (output) is available to act as
the system interrupt. As long as there is no motion the system
can remain in Sleep mode allowing maximum battery power
saving. Based on the last detected motion the ADNS-3040
navigation engine enters various power saving modes when
no new motion occurs. These power saving features make the
ADNS-3040 ideally for wireless applications.
