利用 USB2I2C开发板和软件实现了对CMOS图像传感器的在线调试。该系统运行稳定，体积小，外围电路简单，可灵活应用于多种CMOS图像传感器在线调试的场合以进行图像质量调整。本系统在调试过程中能生成调试log文件和寄存器配置文件。调试log文件记录调试过程中寄存器更改过程，可方便追踪、查看调试过程；寄存器配置文件保存最终调试结果，方便用户进一步的应用。(Use USB2I2C development board and software realization of the CMOS image sensor circuit debugging. The system is stable, small, simple external circuit can be flexibly applied to a variety of CMOS image sensors in-circuit debugger occasion for image quality adjustment. The system can generate in the debugging process debugging log file and registers the configuration file. Debug log file records the process of debugging registers the change process, can be easily tracked, view the debugging process register configuration file to save the final result debugging, user-friendly application further.)

步进电机28BYJ48型四相八拍电机，电压为DC5V—DC12V。当对步进电机施加一系列连续不断的控制脉冲时，它可以连续不断地转动。每一个脉冲信号对应步进电机的某一相或两相绕组的通电状态改变一次，也就对应转子转过一定的角度（一个步距角）。当通电状态的改变完成一个循环时，转子转过一个齿距。四相步进电机可以在不同的通电方式下运行，常见的通电方式有单（单相绕组通电）四拍（A-B-C-D-A。。。），双（双相绕组通电）四拍（AB-BC-CD-DA-AB-。。。），八拍（A-AB-B-BC-C-CD-D-DA-A。。。）(Stepping Motor 28BYJ48 four-phase eight-phase motor, the voltage DC5V-DC12V. When a series of continuous control pulses are applied to the stepper motor, it can be continuously rotated. Each pulse signal corresponds to the stepper motor of a phase or two-phase winding power state change once, also corresponds to the rotor through a certain angle (a step angle). When the change in the power-on state completes one cycle, the rotor turns one pitch. Four-phase stepper motors can be operated in different power-up modes. The common power-up modes are: single-phase winding power (ABCDA ...), double (dual-phase winding)-DA-AB-...), eight beats (A-AB-B-BC-C-CD-)
