电力载波抄表系统里的电力载波采集器,采集数据再通过RS485向主站发送.-Meter Reading System Power Line Carrier Power Line Carrier" s collector, collecting data through RS485 sent to the master station.

用485实现单片机之间的串行通信。 主机部分发送从机地址，等待从机响应，从机准备好就发数据,发完就接收从机的响应，接受成功就跳出循环，否则重发。-MCU with 485 Serial Communication between. Host of this address from the plane, waiting for the response from the plane, from the plane ready to discuss the data, finished on the reception of the response from the plane. set aside for recycling success, otherwise re-issued.

一个PS2键盘单片机, 使用Philips的接口+8051,写的不错,非常值得学习.-a PS2 keyboard microcontroller, the use of the interface, Philips 8051, was a good, very worth learning.

使用1520控制器的12232点阵液晶模块的51单片机控制C代码,keil编译通过,使用端口直接连接方法,P1口为数据口,控制线在P3部分端口-1520 controller using dot matrix LCD module 12232 51 C MCU control code keil compiled by the use of ports directly connected, I P1 for data export, the line of control in some ports P3

智能门禁系统采用凌阳十六位单片机作为系统控制核心，利用其强大的语音识别功能，不仅实现了语音播放功能，完成了语音提示的要求，而且实现了语音控制门禁系统；利用其内置的Flash闪存，实现了密码的断电保护。除此而外，在键盘输入方面，强大的功能选择键满足了系统的要求；16*2液晶显示器的选择使操作要求清晰明了。此套智能门禁系统强烈体现了其人性化的一面-Intelligent access control system uses the Sunplus 16 single-chip system control as the core, to use its powerful voice recognition features, not only realize the voice playback, the voice prompts to complete the requirements, but also realize the voice control of access control systems the use of its Purchase of Flash memory, realize the power to protect your password. Furthermore, in keyboard input, the choice of powerful features to meet key requirements of the system 16* 2 LCD display options so that operating requirements clear. This set of intelligent access control system strongly reflects its human side
