指南针的调试程序

应用背景本程序给出了如何为 计数器应用信息；BASYS2 board，这是一个从Digilent为那些不熟悉它的FPGA板。关键技术它展示了如何建立一个计数器和建立在ISE格式项目所需步骤，应用写作的计数器的VHDL代码，写引脚约束文件（。UCF）最后为BASYS2 board位文件。

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.
