3 / 16 page 3 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, flexibility 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 difficult 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 predefined 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 firmware file contents into the ADNS-6000. The firmware file is an ASCII text file 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.

Two phototransistors are connected in a source-follower configuration. 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 off 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. |
