Invalid addresses: Writing invalid address will have effect. Reading from invalid address will return zeros. Collision detection SDIO: only time that ADNS-2030 drives SDIO line during READ operation. avoid data collisions, microcontroller should relinquish SDIO before falling edge SCLK after last address bit. ADNS-2030 begins drive SDIO after next rising edge SCLK. ADNS-2030 relinquishes SDIO within falling SCLK edge after last data bit. microcontroller begin driving SDIO time after that. order maintain power consumption normal operation when pulled high, microcontroller should leave SDIO floating until next transmission (although that will cause communication difficulties).

Notes Power Serial Port sequence which VDD, SCLK SDIO during powerup affect operation serial port. diagram below shows what happen shortly after powerup when microprocessor tries read data from serial port.

When sent micro, ADNS-2030 valid address, drives SDIO line high within (see detail Figure Figure 27). This results fight SDIO.

Solutions There different ways solve problem: waiting serial port watchdog timer time out, using line reset serial port. Serial port watchdog timer timeout (Refer Figure 35.) microprocessor waits least tSPTT from valid, will ensure that ADNS-2030 powered watchdog timer timed out. This assumes that microprocessor ADNS-2030 share same power
supply. not, then microprocessor must wait tSPTT from ADNS-2030 valid. Then when SCLK toggles address, ADNS-2030 will sync with microprocessor. Sync (Refer Figure 36.) line used resync serial port. microprocessor waits from valid, then outputs valid pulse (Refer Figure 14), then serial port will ready data.

Once pixel dump command given, sensor writes address value first pixel into Data_Out_Upper Data_Out_Lower registers. Data_Out_Lower status data. high, data valid. Once low, data that particular read valid should saved. pixel address data will then incremented next frame. Once pixel dump complete, PixDump register 0x0a should zero. obtain accurate image Pixel Dump image, needs turned changing sleep mode configuration register 0x0a always awake.

Data Type: Sixteen word. USAGE: Units clock cycles; default value Read Shutter_Upper first, then Shutter_Lower. They should read consecutively. shutter adjusted keep average maximum pixel values within normal operating ranges. shutter value different every frame. each frame, shutter only change 1/16 current value. Shown below graph sequentially acquired shutter values, while sensor moved slowly over white paper.
