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

Windows

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 firmware for 15-

20ms. In this reference design there are three switches:

left, Z-wheel, and right.

USB Connection

The Sunplus SPCP825A has a configuration register that

switches control from the SIE to manual control on the

D+ and D- pins. This allows the firmware to dynamically

configure itself to operate as a USB mouse. The firmware

for this reference design will automatically detect the

host topology (USB). The connections for the connectors

are shown in Figure 3 below.
