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-6010 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-6010 Optical Navigation
Sensor. A schematic of the Sunplus, SPCP825A USB micro-
controller to the ADNS-6010 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-6010 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-6010 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 45 inches per
second and accelerations up to 20g.
The ADNS-6010 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. The ADNS-6010 enables 400cpi,
800cpi, 1600cpi or 2000cpi performance.
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-
6010.
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.

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 SPC825A_A6010.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cation.
Communications between the Sunplus SPCP825A and
the ADNS-6010 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 through PB0 (NCS), the
PB2 (SCLK), PB3 (MISO), and PB1 (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 PB2. Therefore, the USB microcontroller
always initiates communication. Data sent by the ADNS-
6010 optical sensor is received on the PB3 (MISO), and
data is shifted out to the ADNS-6010 through the PB1
(MOSI). See the schematic in Appendix A. When writing
to the ADNS-6010, the microcontroller drive both the
SCLK and the MOSI lines. When reading from the ADNS-
6010, the microcontroller drives both the SCLK and MOSI
lines initially. After tSRAD delay, the ADNS-6010 will drive
the data via MISO. The microcontroller is only driving the
SCLK line (outputs SCLK for the serial interface).
Optical Sensor
Avago Technologies ADNS-6010 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-6010’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-6010
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-6010 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
7080fps). Besides, ADNS-6010 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-6010 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

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.
Figure 2. Optics Quadrature Signal Generation
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 dynami-
cally congure itself to operate as a USB. The rmware
for this reference design will automatically detect the
host topology (USB) at plug-in and will congure itself
for operation on that bus. If a USB host connection is
detected then the rmware will enable the VREG pin,
such that the 1.3k ohm resistor connected to the D- line
can be pulled up to 3.3V. It is this action that causes the
host to recognize that there is a low-speed USB peripheral
attached. The connections for the connectors are shown
in Figure 3 below.

Enabling the SROM
The ADNS-6010 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-
6010 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.
For more information, please refer to the ADNS-6010
datasheet.

Eye Safety
The ADNS-6010 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-6010 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 Technologies 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-
6010 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.
LASER Power Adjustment Procedure
1. The ambient temperature should be 25C +/- 5C.
2. Set VDD3 to its permanent value.
3. Ensure that the laser drive is at 100% duty cycle by
setting bit 6 of register 0x0A to 0.
4. Program the LP_CFG0 and LP_CFG1 registers to achieve
an output power as close to 506uW as possible without
exceeding it.
Good engineering practices should be used to guarantee
performance, reliability and safety for the product design.
LASER Output Power
The laser beam output power as measured at the naviga-
tion surface plane is specied below. The following condi-
tions apply:
1. The system is adjusted according to the above
procedure.
2. The system is operated within the recommended
operating temperature range.
3. The VDD3 value is no greater than 50mV above its value
at the time of adjustment.
4. No allowance for optical power meter accuracy is
assumed.

Firmware Implementation
The rmware for this reference design is written in the
Sunplus assembly language. The following les are
required to compile the mouse rmware.
SPCP825A _A6010.asm –main mouse rmware.
hiddesc3.asm - 3 buttons mouse mode USB descriptor ROM
tables.
Hiddesc5.asm – USB 3 Key Mode Descriptor Rom Tables
pro_6010.asm – Routine to access ADNS-6000 sensor
register.
SPCP825A.inc – The SPCP825A I/O registers denition.
adns6010_SROM.inc – ADNS-6000 SROM rmware.
ADNS6010.inc – ADNS-6010 Sensor registers include les.
delay.inc – SPCP825A delay loop subroutine.
decode_setup.inc – USB descriptor and request constants.
det_Z.inc – SPCP825A Z-axis event handler.
DET_KEY.inc – SPCP825A button event handler.
MODE_SEL.inc – Detect Bus status for USB mode.
StartUp.asm – This include le is for AVAGO TECHNOLOGIES
ADNS-6010 Mouse Sensor laser power calibration.
At power up, the rmware examines the host interface
and automatically determines the mouse USB host con-
nection. Then the host rmware congures itself to
operate on the detected interface.
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 _A6010.asm.
Start_up – This function is used for mouse sensor calibra-
tion. It proceeds for calibration when the output power
measurement device is plugged to the mouse. Otherwise
it skips the calibration process and proceeds to USB ini-
tialization.
Read_LP_CFG_REG – This function reads the calibrated
laser power conguration register from EEPROM.
reset_ands6010 – This function is responsible for
resetting the hardware, loading the SROM (Shadow ROM)
rmware into the ADNS-6010 optical sensor. Then ReadSPI
and WriteSPI are called to set the resolution of the sensor
to 2000cpi. 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.
hard_reset – This routine resets the serial interface and
the ADNS-6010 internal registers by generating a pulse
on the RESET pin.
LoadSROM – This routine is used to load the SROM
(Shadow ROM) rmware into the ADNS-6010 optical
sensor. It is called after hard_reset.
WriteSPI – Writes to the ADNS-6010 register. A write
operation consists of two bytes. The rst byte contains
the address (7 bits) and has“1” as its MSB. The second byte
contains data. The microcontroller is responsible to drive
both the SCLK and the MOSI lines.
ReadSPI – Reads the desired ADNS-6010 registers. A read
operation is composed of two parts. First, the microcon-
troller performs a write to the ADNS-6010, sending the
address of the target register to be read. The microcon-
troller drives both the SCLK and MOSI lines. After tSRAD
delay, the ADNS-6010 will drive the data via MISO. The mi-
crocontroller is only driving the SCLK line (outputs SCLK
for the serial interface).
CheckProductID – This function checks the product ID
of the sensor chip being used. The ID returned should
match with the ADNS-6010’s ID. Otherwise the program is
trapped in the dead loop, i.e. the device is unusable.
Check_SROM_ID – This function is to check the SROM
ID, if product device and program ID do not match, the
program is trapped in the dead loop, and thus the device
is unusable.
disable_laser – This function is called to disable the
operation of the laser.
AdjustLaser – This function is used to adjust the laser
power. To meet Class 1 eye safety requirement, manu-
facturers are required to program LP_CFG0 and LP_CFG1
to get laser output power as close to 506uW as possible.
This is done by using a power meter which can measure
the output laser power during mouse calibration.
SetDCMode – Set the laser to continuous on mode for
laser calibration purpose.
SetShutterMode – This function is responsible to on the
laser only when illumination is required. This is to ensure
safety to the users as well as for power saving.
enable_laser – This function is to enable the laser.
check_susp – This function is used to determine whether
the mouse is in the suspend mode.
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.
detect_key_change – This function is used to detect left,
right or middle button changes.
ReadMotionReg – Reads the ADNS-6010 Motion
register. The data returned from this register will be used
to determine if any motion has occurred or if any fault
condition exists.
ReadDeltaX – Reads the ADNS-6010 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-6010 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.
Report_mouse_data – This function is used to send
buttons, X, Y and Z-wheel data to the computer.

8
USB Functions
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.
Mice_USB_Loop – This routine initializes the USB related
parameters and then loads the SROM rmware into the
ADNS-6010 sensor before proceeding to AdjustLaser. The
program then goes to the main_loop.
main_loop – This function spins in an innite loop waiting
for an event that needs servicing. The sample_mouse
function is called within this loop to retrieve any new
motion or button information. The data received from
this function 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.
getInterfaceProtocol – This routine is entered whenever
a GET PROTOCOL request is received. This request initiates
a control-read transaction that tells the host if the mouse
is congured for boot or report protocol. 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 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.
Bit 7 Bit 0
Byte 0 0 0 0 0 0 Middle Right Left
