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.

ucos在arm上的移植代码，欢迎大家学习参考。共同学习，共同进步。-CENTER arm in a transplant code, we welcome the study reference. Common learning and common progress.

该文档分为两部分，第一部分是51系列计数器的一个程序，设计到开关中断，实现计数功能，计数到178；第二部分是一个频率，实际上也是对51单片机中计数器的一个应用，并且结合了驱动数码管的功能，是一个很好的中断控制，与外设控制相结合的一个程序。

UcosII 实时操作系统在LPC1768单片机上的实现。 只是空白的模板，有两个任务，几个信号量。 可用于二次开发。

CPU是S3C44B0X,是学习时可用来参考,很好的原理图-CPU is the study is available for reference and a good diagram

红外遥控器已被广泛使用在各种类型的家电产品上，它的出现给使用家器提供了很多的便利。红外遥控系统一般由红外发射装置和红外接受设备两大部分组成。红外发射装置又可由键盘电路、红外编码芯片、电源和红外发射电路组成。红外接收设备可由红外接收电路、红外解码芯片、电源和应用电路组成。通常为了使信号能更好的被传输发送端将基带二进制信号调制为脉冲串信号，通过红外发射管发射。本设计采用Atmega8作为红外发射编码和接收解码芯片。-Infrared remote control has been widely used in various types of household electrical appliances, it" s there to provide the users a lot of convenience. Infrared remote control system in general by the infrared emission devices and infrared devices to accept the composition of two major parts. Infrared emission circuit device can be by keyboard, infrared encoder chip, power and infrared emission circuit. By the infrared receiver infrared receiver circuit equipment, infrared decoder chip, power supply and application circuit. Usually better in order to signal the sending end of the transmission to binary base-band signal for pulse modulation, through the launch tube infrared emission. The design uses infrared emission Atmega8 as encoding and decoding chip receiver.

飞思卡尔的键盘中断源代码,C语言写的,很不错的-Freescale keyboard interrupt source code, C language, and very good

在这里是要从 89s51 得到新工作的程序。 这是最重要的参数为工作和你将上涨享受。
