Description
The ADNS-2051 is a low cost optical sensor used to implement a non-mechanical tracking engine for computer mice. It is based on optical navigation technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically deter- mining the direction and magnitude of movement. The sensor is housed in a 16-pin staggered dual inline package (DIP) that is designed for use with the HDNS-2100 Lens and HDNS-2200 Clip and HLMP-ED80-XXXXX (639 nm LED illuminator source). There are no moving parts, and precision optical alignment is not required, facilitating high volume assembly. The output format is two channel quadrature (X and Y direction) which emulates encoder photo- transistors. The current X and Y information are also available in registers accessed via a serial port. Default resolution is specified as 400 counts per inch (cpi), with rates of motion up to 14 inches per second (ips). Resolution can also be pro- grammed to 800 cpi. The part is programmed via a two wire serial port, through registers. Theory of Operation The ADNS-2051 is based on Optical Navigation Technology. It contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), a two-channel quadrature output, and a two wire serial port. The IAS acquires microscopic surface images via the lens and illumination system provided by the HDNS-2100, 2200, and HLMP-ED80-XXXXX LED. These images are processed by the DSP to determine the direction and distance of motion. The DSP generates the Δx and Δ y relative displacement values that are converted into two channel quadrature signals.

If so, then the user should read registers 0x03 and 0x04 to get the accumulated motion. It also tells if the motion buffers have overflowed and whether or not an LED fault occurred since the last reading. The current resolution is also shown.

Reading this register freezes the Delta_X and Delta_Y register values. Read this register before reading the Delta_X and Delta_Y registers. If Delta_X and Delta_Y are not read before the motion register is read a second time, the data in Delta_X and Delta_Y will be lost. 2. Agilent RECOMMENDS that registers 0x02, 0x03 and 0x04 be read sequentially. 3. Internal buffers can accumulate more than eight bits of motion for X or Y. If either one of the internal buffers overflows, then absolute path data is lost, and the OVFX or OVFY bit is set. These bits (OVFX and OVFY) are cleared once some motion has been read from the Delta_X and Delta_Y registers, and if the buffers are not at full scale. Since more data is present in the buffers, the cycle of reading the Motion, Delta_X and Delta_Y registers should be repeated until the motion bit (MOT) is cleared. Until MOT is cleared, either the Delta_X or Delta_Y registers will read either positive or negative full scale. If the motion register has not been read for a long time, at 400 cpi it may take up to 16 read cycles to clear the buffers, at 800 cpi, up to 32 cycles. 4. FAULT is a sticky bit that is cleared by reading the Motion register. It signifies that an LED fault has occurred since the last time the motion register was read. Once an LED fault has cleared, the hardware will drive the LED normally. 80 81 FE FF 00 01 02 7E 7F -128 -127 -2 -1 0 +1 +2 +126 +127MOTION DELTA_X B i t 7654 3210 Field X 7 X6 X5 X4 X3 X2 X1 X0 Data Type: Eight bit 2‘s complement number.

Note: Since part of the system test is a RAM test, the RAM will be overwritten with the default values when the test is done. If any configuration changes from the default are needed for operation, make the changes AFTER the system test is run. This operation requires substantially more time to complete than other register transactions.

Pixel Dump command Pixel Address Pixel Data (Lower 6 bits) Once the pixel dump command is given, the sensor writes the address and the value for the first pixel into the Data_Out_Upper and Data_Out_Lower registers. The MSB of Data_Out_Lower is the status bit for the data. If the bit is high, the data are NOT valid. Once the MSB is low, the data for that particular read are valid and should be saved. The pixel address and data will then be incremented on the next frame. Once the pixel dump is complete, the PixDump bit in register 0x0a should be set to zero. To obtain an accurate image, the LED needs to be turned on by changing the sleep mode of the configuration register 0x0a to always awake.

Changing the frame rate results in changes in the maximum speed, acceleration limits, and dark surface performance. To read from the registers, read Frame_Period_Upper first followed by Frame_Period_Lower. To write to the registers, write Frame_Period_Lower first followed by Frame_Period_Upper. The maximum value of the shutter is dependent upon the frame rate and clock frequency. The formula for the maximum shutter value is: Clock Frequency Frame RateMax.

Radiometrically Tested Precision Optical Performance AlInGaP II (aluminum indium gallium phosphide) LEDs offer increased sensor-based application design flexibility. High-resolution radiometric intensity bins (mW/sr) enable customers to precisely match LED lamp performance with sensor functionality. Visible LEDs offer new styling alternatives — light can be leveraged to develop more attractive products. In comparison to invisible infrared sources, safety concerns are significantly improved by the human autonomic pupil response and reflexive movement away from bright light. Visible LEDs further indidcate system on / off status. The AlInGaP II technology provides extremely stable light output over very long periods of time, with low power consumption. These lamps are made with an advanced optical grade epoxy system offering superior high temperature and moisture resistance performance in outdoor systems. The epoxy contains both uv-a and uv-b inhibitors to reduce the effects of long term exposure to direct sunlight. Please contact your Agilent Technologies Representative for more information and design for manufacture advice.

HDNS-2200 #001 Solid-State Optical Mouse LED Assembly Clip Technical Data The HDNS-2200 LED Assembly Clip is designed to provide optical and mechanical coupling of a standard T1 3/4 (5 mm diameter) LED to the HDNS-2100 Solid State Optical Mouse Lens. This coupling is essential to achieve the proper illumination required for the HDNS-2000 Sensor to operate on a wide variety of surfaces. The clip also provides a mechanical compression feature which locates over the HDNS-2000 and is used to ensure that a light mechanical contact is always maintained between the HDNS-2000 Sensor and the HDNS-2100 Lens when assembled. The inner surface of the top case of the mouse housing should be designed to lightly compress this feature when the case is closed at final assembly.
