用C实现广告灯箱自动装置1、直流电机控制系统，控制广告牌的升降。 2、定时翻转广告，可由按键设定时长。 3、时间设置，5：00-22：00正常工作，其余时间不工作，时间可以调整。 4、到达广告的边缘部分广告停止翻转。 5、广告可以由按键设置升/降。 6、白天时间广告灯不亮，光线较暗时广告灯才亮，测试灯的好坏时可以手动控制灯光。 7、断电时保存时间及按键的设置，使广告牌到达边缘部分。 -C implementation using automatic device 1 advertisement light box, DC motor control system, control the rise and fall of advertising. 2, ads from time to time reversal, length of time set by the keys. 3, time set ,5:00-22: 00 normal job, the rest of the time does not work, time to adjust. 4, Get ads ads stop some of the edge flip. 5, ads can be set up by the button/drop. 6, ads during the day time lights are not bright, low light only bright lights when the ads to test the quality of light can control the lights manually. 7, when power-off time and save the settings button so that the edge part of advertising arrival.

此程序是在AVR单片机atmega169P处理器的程序，开发环境为ICC AVR 7.13pro，我在网上找了好久很少有MT8888模拟单片机读写时序的驱动程序，更少有AVR处理器的，所有今天贡献出来，希望对大家有帮助。-This procedure is atmega169P single-chip processors in the AVR process, development environment for the ICC AVR 7.13pro, I was online looking for a long time simulation of very few MT8888 single-chip driver to read and write timing, fewer have AVR processor , all contribute today, I hope all of you help.
