For this project you need a 3.7v power supply that prepared by LM317 regulator. So you need MAX232 for connect uart to pc .my AVR chip project is Mega8 that you can program on any Avr chip have 2kbyte rom. In bascom spi hardware don’t work correct, so I have to software spi ,but the software spi configure have low speed into hardware spi.

该项目首先是利用单片机对鱼缸的温度进行智能控制。首先通过外部按键对鱼缸所需温度进行设定。温度传感器 DS18B20 采集温度信息在外围的 LCD 上显示出来。其次是利用光电耦合器判断有无鱼饵，若无鱼饵，发出提示，若有鱼饵，则执行自动投食或手动投食功能。(The project first is the use of single-chip microcomputer to control the temperature of the fish tank. First, the temperature of the fish tank is set by the external button. The temperature sensor DS18B20 collects the temperature information to display on the periphery LCD. Followed by using photoelectric coupler to determine whether the bait, if there is no bait, alert, if there is a bait, automatic throw in and throw food or manually cast and functional food.)

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.)
