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.)
