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.

ARM的串口，LED以及PWM裸机程序，对于初学ARM的朋友很有用-ARM" s serial port, LED as well as the PWM bare-metal process, is useful for beginners to use ARM" s friends

ARM7的ads环境下的画圆的实现，在用户环境下得应用！采用周立功公司的LPC2103系列的板子！-ARM7-under ads drawcircle the implementation, a user application environment! Ligong weeks using the company" s board LPC2103 series!

本文介绍了如何用AD识别用户输入的键盘的方法，较之点阵识别有其不可替代的优势；因为如果用4*4的话须消耗8个I/O口，而如果系统有AD功能的话就可能轻松解决了。 单片机8051F330发给ARM然后发给电脑。 其原理就是利用电阻的分压，按键时产生不同的电压，再用中断快速读取电压；然后对其进行编码，通过串口软件EASYARM在个人电脑里显示；经实验观察，效果还可以。 -This article describes how to use AD to identify the user s keyboard input methods, compared with dot-matrix recognition has its irreplaceable advantages because if we use 4* 4, then to be consumed eight I/O port, and if the system function in AD, then on may be easily resolved. Singlechip 8051F330 distributed computer and then distributed to ARM. Its principle is to use the sub-ballast resistor, when keys have different voltage, and then quickly read voltage interruption then encode, through the serial port software EASYARM in the personal computer display by experimental observation, the effect can also be.

用verilog编程语言实现的ifft程序，用的器件是赛灵思的，开发环境是ise，采用流水线结构，值得下载借鉴，蝶形算法采用基2分解，可用于数字滤波，信号处理等领域，希望那个大家多多支持......
