usb下载线，可以完全取代并口下载，为没有并口的笔记本提供方便。-usb download cable, you can completely replace the parallel port to download, there is no parallel port for the notebook with ease.

tcp_ip协议栈的ucos代码，主要用于嵌入式系统开发，已经移植到51系统单片机中，通过keil可进行编译，ucos经过最简化改造！特别推荐-tcp_ip CENTER protocol stack code, mainly for embedded system development, has been ported to 51 SCM system, through c51 can be compiled after the most simplified CENTER transformation! Preferred!

某公司安装了电子门，要设计门禁系统： 公司的雇员可以凭借密码、胸卡或指纹进入公司 计算机根据雇员的验证方式对其身份进行验证 管理员在监控室可以通过按钮直接开启电子门 访客可以按门铃请求进入，由管理员为其放行 管理员可以为新职员设置密码 -A company to install an electronic gate, to design access control systems: the company" s employees can rely on passwords, badges or finger into the company computer, authentication of the employee to verify their identity can be an administrator in the control room directly through the button to open electronic gates that visitors can rang the doorbell of the request to enter an administrator can be released by the administrator of its staff to set a password for the new

提出了一个由AT89C52单片机控制步进电机的实例。可以通过键盘输入相关数据, 并 根据需要, 实时对步进电机工作方式进行设置, 具有实时性和交互性的特点。该系统可应用于 步进电机控制的大多数场合。实践表明, 系统性能优于传统的步进电机控制器。-Put forward a AT89C52 single-chip stepper motor control example. Through the keyboard input data, and in accordance with the needs of real-time work on the stepper motor set up, with real-time and interactive features. The system can be applied to stepper motor control of the majority of occasions. Practice shows that system performance is superior to traditional stepper motor controller.
