实时时钟

前段时间做了一个AT91M55800的芯片测试，测试通过后，现在把一个启动AT91M55800芯片的初始化程序上传。每个人的硬件不同，但是可以借鉴一下。-earlier done a Degital chip test passed, now a start Degital chips upload initialization procedures. Each person"s different hardware, but we can learn some lessons from.

资源描述STM32采用TIM1的PWM输出，控制直流无刷电机 上传一个基本初级版的程序 PA8 PA9 PA10 PB13 PB14 PB15是PWM输出口 PC5接个电位器调节速度 PB12电源指示灯 PB5正转指示 PB2反转指示 PB0按键开机 PB1按键正反转 宏定义DEBUG可以软件仿真（DEBUG用来开启相关变量，以及变换霍尔相序）

本文介绍了红外多路遥控系统。红外多路遥控系统可实现16路的红外开关控制。以码分制多通道红外遥控为设计的基本思路。通过键盘及代码生成电路、编码、脉冲调制振荡和红外发射构成红外发射电路。通过红外接收，解码以及由单片机控制的医码控制电路组成红外接收电路。-The passage has introduced the nfrared multichannel system of remote control. The infrared multichannel system of remote control can realize the infrared switch control of 16 roads. With yard divide into system the basic train of thought with much passageway infrared remote control of design. Through keyboard and code generation circuit, coding and pulse modulation vibration with infrared project to form infrared project circuit. Pass infrared take over , decode as well as the medical yard control circuit composition that controled by single flat machine are infrared to take over circuit.

应用背景keil工程用c语言编写完成，完成四位一体共阳八段数码管动态显示0到9，实测完美运行。关键技术通过调用函数对单片机进行控制完成对四位一体共阳数码管的操作，实验从0到9的动态显示。

Altera软件NIOS II高版本中实现TCP/IP所用的协议栈为NicheStack，常用的例程有2个，web_server和simple_socket_server，这篇文章只叙述simple_socket_server例程实现的过程。这里DM9000A的驱动和上篇博文中基于LWIP的驱动不同。
