Optical Mouse Designer’s Kit
Design Guide
Introduction
The Universal Serial Bus (USB) is an industry standard
serial interface between a computer and peripherals
such as a mouse, joystick, keyboard, UPS, etc. This design
guide describes how a cost-eective USB optical mouse
can be built using the Sunplus, SPCP825A USB microcon-
troller and the Avago Technologies ADNS-6000 optical
sensor. The document starts with the basic operations of
a computer mouse peripheral followed by an introduc-
tion to the Sunplus SPCP825A USB microcontroller and
the Avago Technologies ADNS-6000 Optical Navigation
Sensor. A schematic of the Sunplus SPCP825A USB micro-
controller to the ADNS-6000 optical sensor and buttons
of a standard mouse can be found in Appendix A. The
software section of this application note describes the ar-
chitecture of the rmware required to implement the USB
mouse functions. The Sunplus SPCP825A data sheet is
available from the Sunplus web site at www.sunplus.com
. The ADNS-6000 data sheet is available from the Avago
Technologies web site at www.avagotech.com. USB docu-
mentation can be found at the USB Implementers Forum
web site at www.usb.org.
ADNS-6000 laser mouse set is the world’s rst laser-illumi-
nated navigation system. With laser navigation technol-
ogy, the mouse can operate on many surfaces that prove
dicult for traditional LED-based optical navigation.
Its high-performance architecture is capable of sensing
high-speed mouse motion -- velocities up to 20 inches
per second and accelerations up to 8g.
The ADNS-6000 sensor along with the ADNS-6120 lens,
ADNS-6230-001 clip and ADNV-6340 laser diode form
a complete and compact laser mouse tracking system.
There are no moving parts, which means high reliabil-
ity and less maintenance for the end user. In addition,
precision optical alignment is not required, facilitating
high volume assembly.
Optical Mouse Basics
The optical mouse measures changes in position by
optically acquiring sequential surface images (frames),
and mathematically determining the direction and
magnitude of movement. The Z-wheel movement is done
in the traditional method by decoding the quadrature
signal generated by optical sensors. This design guide
shows how to connect to and manage a standard con-
guration of mouse hardware, as well as handle the USB
protocols. Each of these protocols provides a standard
way of reporting mouse movement and button presses to
the PC.
Introduction to the Sunplus, SPCP825A
The Sunplus, SPCP825A is a general purpose OTP USB mi-
crocontroller. It has dual USB speed, namely low and full
speed. It can support PS/2 mode. The transceiver is fully
controlled by the rmware. Moreover the USB SIE provides
good exibility for rmware to handle USB protocol. The
built-in PLL allows CPU to work at 6MHz or 12MHz by
using only one 6MHz crystal or resonator.
Serial Peripheral Interface (SPI)
The Sunplus SPCP825A provides a SPI compatible
interface. The SPI circuit supports byte serial transfer in
either Master or Slave mode. The integrated SPI circuit
allows the Sunplus SPCP825A to communicate with
external SPI compatible hardware, in this case the ADNS-
6000.

Firmware Congurable GPIO
The reference rmware is congured to use the GPIO pins
as shown on the schematic in Appendix A. However, it
may be more optimal to use a dierent I/O conguration
to meet the mechanical constraints of PCB design. The
reference rmware is designed to be easily congured
to another set of pin connections. This is accomplished
through changes in the I/O denitions at the beginning
of the SPCP825A_A6000.asm listing. The following state-
ments are the pin denitions as they exist today. The
rmware will use these denitions to read and congure
the GPIO pins, without any other modications.
Communications between the Sunplus SPCP825A and
the ADNS-6000 are done through the integrated SPI
interface. The serial port cannot be activated while the
chip is in power down mode (NPD low) or reset (RESET
high). When the SPI is enabled thru PB0 (NCS), the PB2
(SCLK), PB1 (MISO) and PB3 (MOSI) GPIO pins serve
special functions to enable the SPI interface to talk with
external hardware. During normal operation, the Sunplus
SPCP825A SPI is always congured as a Master to output
the serial clock on PB7. Therefore, the USB microcontroller
always initiates communication. Data sent by the ADNS-
6000 optical sensor is received on the PB1 (MISO), and
data is shifted out to the ADNS-6000 through the PB3
(MOSI). See the schematic in Appendix A. When writing
to the ADNS-6000, the microcontroller drive both the
SCLK and the MOSI lines. When reading from the ADNS-
6000, the microcontroller drives both the SCLK and MOSI
lines initially. After tSRAD delay, the ADNS-6000 will drive

Hardware Implementation
The standard hardware to implement a mouse is shown
in Figure 1. For X and Y movement, the optical sensor
is used. The Z- wheel movement is detected by a set of
optical sensors that output quadrature signals. For each
button there is a switch that is pulled up internally by the
built in pull up resistors. The D - line is pulled up via a 1.3k
ohm resistor connected to the VREG pin.

Figure 2. Optics Quadrature Signal Generation
Optical Sensor
Avago Technologies ADNS-6000 optical sensor is used in
this reference design as the primary navigation engine.
This Optical Navigation Technology contains an Image Ac-
quisition System, a Digital Signal Processor, a two channel
quadrature output, and a four-wire serial port. The
Sunplus SPCP825A periodically reads the ADNS-6000’s
Delta_X and Delta_Y registers to obtain any horizontal
and vertical motion information happening as a result of
the mouse being moved. The output of the ADNS-6000
optical sensor is 4-wire serial port.
This motion information will be reported to the PC to
update the position of the cursor. The advantages of using
ADNS-6000 optical sensor are the best tracking accuracy,
exibility of programming the optical sensor via the SPI
port, and the automatic frame rate feature (1000fps to
6400fps). Besides, ADNS-6000 optical sensor performs
excellent tracking on dicult surfaces which convention-
al Led based technology is unable to track such as glossy
and smooth surfaces. In addition, Burst mode is another
special serial port operation mode that may be used to
reduce the serial transaction time for three predened
operations: motion read and SROM download and frame
capture. The speed improvement is achieved by continu-
ous data clocking to or from multiple registers.
Motion Read is activated by reading the Motion_Burst
register. The ADNS-6000 will respond with the contents
of the Motion, Delta_X, Delta_Y, SQUAL, Shutter_Upper,
Shutter_Lower and Maximum_Pixel registers in that
order. SROM download uses Burst Mode to load the
Avago Technologies-supplied rmware le contents into
the ADNS-6000. The rmware le is an ASCII text le with
each 2-character byte on a single line. Frame Capture is
a fast way to download a full array of pixel values from a
single frame.

Mouse Optics
The motion of Z-wheel is detected using the traditional
method by decoding the quadrature signal generated by
optical sensors. Two phototransistors are connected in
a source-follower conguration. An infrared LED shines,
causing the phototransistors to turn on. In between the
phototransistors and LED is a pinwheel that turns on the
mouse ball rollers. The fan of this pinwheel is mechanical-
ly designed to block the infrared light such that the pho-
totransistors are turned on and o in a quadrature output
pattern. Every change in the phototransistor outputs rep-
resents a count of mouse movement. Comparing the last
state of the optics to the current state derives direction
information. As shown in Figure 2 below, traveling along
the quadrature signal to the right produces a unique set
of state transitions, and traveling to the left produces
another set of unique state transitions. In this reference
design, only the motion at the Z-wheel is detected using
this method.

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 o 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.
*or ADNS-6130-001 for trim lens
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 rmware for 15-
20ms. In this reference design there are three switches:
left, Z-wheel, and right.
USB Connection
The Sunplus SPCP825A has a conguration register that
switches control from the SIE to manual control on the
D+ and D- pins. This allows the rmware to dynamically
congure itself to operate as a USB mouse. The rmware
for this reference design will automatically detect the
host topology (USB). The connections for the connectors
are shown in Figure 3 below.

Eye Safety
The ADNS-6000 and the associated components in the
schematic of Figure A1 are intended to comply with Class
1 Eye Safety Requirements of IEC 60825-1. Avago Tech-
nologies suggests that manufacturers perform testing to
verify eye safety on each mouse. It is also recommended
to review possible single fault mechanisms beyond those
described below in the section “Single Fault Detection”.
Under normal conditions, the ADNS-6000 generates the
drive current for the laser diode (ADNV-6340). In order to
stay below the Class 1 power requirements, resistor Rbin
must be set at least as high as the value in the bin table,
based on the bin number of the laser diode and LP_CFG0
and LP_CFG1 must be programmed to appropriate values.
Avago Technology recommends using the exact Rbin
value specied in the bin table to ensure sucient laser
power for navigation. The system comprised of the ADNS-
6000 and ADNV-6340 is designed to maintain the output
beam power within Class 1 requirements over component
manufacturing tolerances and the recommended tem-
perature range when adjusted per the procedure below
and when implemented as shown in the recommended
application circuit of Figure A1. For more information,
please refer to Eye Safety Application Note 5088.

Enabling the SROM
The ADNS-6000 must operate from the externally loaded
programming. This architecture enables immediate
adoption of new features and improved performance
algorithms. The external program is supplied by Avago
Technologies as a le which may be burned into a pro-
grammable device. A microcontroller with sucient
memory may be used. On power-up and reset, the ADNS-
6000 program is downloaded into volatile memory using
the burst-mode procedure described in the Synchronous
Serial Port section. The program size is 1986 x 8 bits.

decode_setup.inc – USB descriptor and request
constants.

DET_KEY.inc – SPCP825A button event handler.
USB Interface
All USB Human Interface Device (HID) class applications
follow the same USB start-up procedure. The procedure is
as follows
1. Device Plug-in
When a USB device is rst connected to the bus, it is
powered and running rmware, but communications on
the USB remain non-functional until the host has issued
a USB bus reset.
2. Bus Reset
The pull-up resistor on D– noties the hub that a low
speed (1.5 Mbps) device has just been connected. The
host recognizes the presence of a new USB device and
initiates a bus reset to that device.
3. Enumeration
The host initiates SETUP transactions that reveal general
and device specic information about the mouse. When
the description is received, the host assigns a new and
unique USB address to the mouse. The mouse begins
responding to communication with the newly assigned
address, while the host continues to ask for information
about the device description, conguration descrip-
tion and HID report description. Using the informa-
tion returned from the mouse, the host now knows the
number of data endpoints supported by the mouse (2). At
this point, the process of enumeration is completed.
Notes
1. idVendor should be changed to the value as supplied by the USB-IF
2. idProduct should be assigned for specic product.
3. MaxPower value should be changed as per specic circuit’s current
draw.
4. Post Enumeration Operation
Once communication between the host and mouse is es-
tablished, the peripheral now has the task of sending and
receiving data on the control and data endpoints. In this
case, when the host congures endpoint 1, the mouse
starts to transmit button and motion data back to the
host when there is data to send. At any time the periph-
eral may be reset or recongured by the host.
USB Requests – Endpoint 0
Endpoint 0 acts as the control endpoint for the host.
On power-up endpoint 0 is the default communication
channel for all USB devices. The host initiates Control-
Read and Control-Write (see Chapter 8 of the USB speci-
cation) to determine the device type and how to congure
communications with the device. In this particular design,
only Control-Read transactions are required to enumerate
a mouse. For a list of valid requests see Chapter 9 of the
USBG specication. In addition to the standard “Chapter
9” requests, a mouse must also support all valid HID class
requests for a mouse.
USB Requests – Endpoint 1
Endpoint 1 is the data transfer communications channel
for mouse button, wheel, and movement informa-
tion. Requests to this endpoint are not recognized until
the host congures endpoint 1. Once this endpoint is
enabled, then interrupt IN requests are sent from the host
to the mouse to gather mouse data. When the mouse is
left idle (i.e. no movement, no new button presses, no
wheel movement) the rmware will NAK requests to this
endpoint. Data is only reported when there is a status
change with the mouse.
Two HID report formats are used in this design. The
boot protocol, as dened by the HID specication, is the
default report protocol that all USB enabled systems un-
derstands. The boot protocol has a three-byte format, and
so does not report wheel information. The HID report de-
scriptor denes the report protocol format. This format is
four bytes and is the same as the report format with the
exception of the fourth byte, which is the wheel infor-
mation. Appendix F of this document lists the USB Data
Reporting Format.

USB Firmware Description
A function call map for USB operation is shown in Figure
6. The following are descriptions of the functions in
SPCP825A _A6000.asm.
IO_initial – This function is use to set the Sunplus micro-
controller as input or output.
Port A(PA) is set as input while both Port B(PB) and Port
C(PC) are set as output. This function also includes setting
and enabling of pull-up resistor for left, right and middle
keys.
clear_ram – This function clears the internal ram of the
microcontroller.
Usb_initial – This function is used to enable the USB
mode. This is done by enabling the watchdog and LVR and
the low speed is selected. The USB reset event interrupt as
well as the set up event interrupt are enabled.
DetectUsbReset – This routine initializes USB interface
service and SPI ports. Then, the normal_mode variable is
compared, if normal_mode is equal to ‘0’then this routine
will invoke the calibration_operation routine to enter cali-
bration loop. If normal_mode variable ag is equal to ‘1’
then Read_LP_CFG_REG is called to load the calibrated
LP_CFG0 and LP_CFG1 register value. Subsequently,
the ADNS-6000 sensor is reset and AdjustLaser routine
is invoked to write the LP_CFG0 and LP_CFG1 value to
the sensor register. Then, SetShuttherMode routine is
called to enable VCSEL in shutter mode and laser output
is enabled.
Default_state – This function is used to set the default
service routing.
SPI_init – This function involves the initialization of SPI.
Read_LP_CFG_REG – This function reads the calibrated
laser power conguration register from EEPROM.
sample_mouse – This routine returns any updates in
the X, Y and Z-wheel motion information. The motion of
the Z-wheel is detected using the traditional method by
decoding the quadrature signal generated by the pho-
totransistors. The X and Y directions of the movement
are obtained by calling the ReadDeltaX and ReadDeltaY
routines. The X, Y, and Z-wheel movement is stored in the
[xCount], [yCount], and [zCount] variables which will be
sent to the host in the main routine.
ReadDeltaX – Reads the ADNS-6000 Delta_X register for
the X movement. Calls the ReadSPI routine to enable the
SPI interface and perform reading operations through the
two wire serial interface. Any new X motion information is
added to the [xCount] variable.
ReadDeltaY – Reads the ADNS-6000 Delta_Y register for
the Y movement. Calls the ReadSPI routine to enable the
SPI interface and perform reading operations through the
two wire serial interface. Any new Y motion information is
added to the [yCount] variable.
DetectKeyLoop – This function is used to detect the left,
right and middle buttons changes.
check_mouse_data –This function is used to determine
whether the buttons, X, Y or Z-wheel data need to be sent
to the host.
reset_adns6000 – This function is responsible for
resetting the hardware, loading the SROM (Shadow ROM)
rmware into the ADNS-6000 optical sensor. The ID from
the device and program are compared. If the ID is not the
same, then the program is trapped in the dead loop, i.e.
the device is unusable.
Report_mouse_data – This function is used to send
buttons, X, Y and Z-wheel data to the computer.
judge_mode – This function is used to check for normal
mouse or calibration mode.
detect_key_change – This function is used to detect left,
right or middle button changes.
ReadMotionReg – Reads the ADNS-6000 Motion
register. The data returned from this register will be used
to determine if any motion has occurred or if any fault
condition exists.
AdjustLaser – the AdjustLaser is used to read the value
from the EEPROM and then store them into the ADNS-
6000 sensor. The mouse will do calibration when the left
button is pressed when the mouse is rst plugged into the
USB port. However if the mouse left button is not pressed,
the value of calibration is already stored in the EEPROM
i.e. there is no need of calibration.
Calibration operation - The calibration mode is dierent
from the AdjustLaser as the calibration mode happens
when the left button is pressed whereas the AdjustLa-
ser is used to read the EEPROM values and put them into
the ADNS-6000 sensor. This means in the Normal mouse
mode, the AdjustLaser is done even in the normal mouse
mode. Actually when the mouse enters the calibration
mode, it cannot come back to the normal mouse mode
without unplugging the USB plug.

Main_loop –This function spins in an innite loop waiting
for an event that needs servicing. sample_mouse and
report_mouse_data are the functions which are called
within this loop to retrieve any new motion or button in-
formation. The data received from these functions will be
loaded into the endpoint 1 buer to be sent to the host.
ep0SetupReceived – This routine is entered whenever a
SETUP packet is received in on endpoint 0. It parses the
packet and calls the appropriate routine to handle the
packet.
ep0InReceived – This routine is entered whenever an IN
packet is received on endpoint 0.
ep0OutReceived – This routine is entered whenever an
OUT packet is received on endpoint 0.
setDeviceConguration – This routine is entered when a
SET CONFIGURATION request has been received from the
host.
setDeviceAddress – This routine is entered whenever
a SET ADDRESS request has been received. The device
address change cannot actually take place until after the
status stage of this no-data control transaction, so the
address is saved and a ag is set to indicate that a new
address was just received. The code that handles IN trans-
actions will recognize this and set the address properly.
setInterfaceIdle – This routine is entered whenever a
SET IDLE request is received. See the HID specication
for the rules on setting idle periods. This function sets the
HID idle time. See the HID documentation for details on
handling the idle timer.
setInterfaceProtocol – This routine is entered whenever
a SET PROTOCOL request is received. This no-data control
transaction enables boot or report protocol.
getInterfaceReport – This routine is entered whenever a
GET REPORT request is received.
getInterfaceIdle – This routine is entered whenever a
GET IDLE request is received. This function then initiates
a control-read transaction that returns the idle time. See
the HID class documentation for more details.
getDeviceConguration – This routine is entered
whenever a GET CONFIGURATION Request is received.
This function then starts a control read transaction that
sends the conguration, interface, endpoint, and HID de-
scriptors to the host.
requestNotSupported – Unsupported or invalid descrip-
tor requests will cause this rmware to STALL these trans-
actions.

Appendix E: USB data reporting format
The USB report has two formats, depending on if boot or report protocol is enabled. The following format is the boot
protocol and is understood by a USB aware BIOS.
Bit 7 Bit 0
Byte 0 0 0 0 0 0 Middle Right Left
Byte1XXXXXXXX
Byte2YYYYYYYY
The following is the USB report protocol format and allows the additional wheel movement information in the fourth
byte. When the wheel is moved forward the fourth byte reports a 0x01, and when moved backward the fourth byte
reports 0xFF. When the wheel is idle, then this byte is assigned 0x00.
