Some details on ADNK-6003-SP01
The ADNK-6003-SP01 reference design mouse unit allows
users to evaluate the performance of the Optical Tracking
Engine (sensor, lens, LASER assembly clip, LASER) over
a USB Sunplus SPCP825A USB Controller. This kit also
enables users to understand the recommended mechani-
cal assembly. (See Appendix C and D)
System Requirements
PCs using Windows
®
95/ Windows
®
98/ Windows
®
NT/
Windows
®
2000 with standard 3-button USB mouse
driver loaded.
Operating (For USB Mode)
Hot pluggable with USB port. The PC does not need to be
powered off when plugging or unplugging the evalua-
tion mouse.
To Disassemble the ADNK-6003-SP01 Unit
The ADNK-6003-SP01 comprises of the plastic mouse
casing, printed circuit board (PCB), lens, buttons, and USB
cable. (See Figure 4.) Unscrewing the one screw located
at the base of the unit can open the ADNK-6003-SP01
unit. Lifting and pulling the PCB out of the base plate can
further disassemble the mouse unit.
Caution: The lens is not permanently attached to the
sensor and will drop out of the assembly.

Mouse Buttons
Mouse buttons are connected as standard switches. These
switches are pulled up by the pull up resistors inside the
microcontroller. When the user presses a button, the
switch will be closed and the pin will be pulled LOW to
GND. A LOW state at the pin is interpreted as the button
being pressed. A HIGH state is interpreted as the button
has been released or the button is not being pressed.
Normally the switches are debounced in fi rmware for 15-
20ms. In this reference design there are three switches:
left, Z-wheel, and right.
USB Connection
The Sunplus SPCP825A has a confi guration register that
switches control from the SIE to manual control on the
D+ and D- pins. This allows the fi rmware to dynamically
confi gure itself to operate as a USB mouse. The fi rmware
for this reference design will automatically detect the
host topology (USB). The connections for the connectors
are shown in Figure 3 below.
