The IPv4 broadcast address, or null for IPv6.

基于AT89C5A60S2控制芯片 DS1302时钟芯片，LCD1602液晶显示的电子钟(DS1302 clock chip based on AT89C5A60S2 controller chip, the LCD1602 LCD electronic clock)

说明：  51单片机蜂鸣器音乐播放器的头文件，可自己更改旋律(51 MCU buzzer music player header file, you can change the melody)

说明：  stm32f103zet时钟实例，说明，程序注解，pdf文档，视频(Stm32f103zet clock instance, description, program notes, PDF document, video)

使用MULTISIM搭建的交通灯系统，带仿真文件与实验报告(MULTISIM built using traffic light system with simulation files and lab reports)

本程序目的是提供使用stm32串口收发一帧数据的一种方法，采用中断方式接受和发送，每进一次中断接收或发送一字节，可以实现pc机与板子通信或板子与板子间通信。注意本程序中外接高速晶振为12M赫兹，而大部分板子为8M赫兹，本程序所用芯片是stm32RBT6(The purpose of this procedure is to provide a method of using STM32 serial port to send and receive a data, using interrupt mode to receive and send, every one into the time interrupt receiving or sending a byte, can realize PC and the communication or board and board communication. Note that this procedure the external high-speed crystal oscillator for the 12M Hz, while the majority of board is 8M Hz, the chip used in this procedure is stm32RBT6)

说明：  自主学习PIC芯片，此书主要讲PIC16F877(Self-learning PIC chip, this book mainly talks about PIC16F877)

ns2_zigbee ========== Performance evaluation of Zigbee based on NS2 This repositories includes the codes of my undergraduate thesis. 1. zigbee.scn: network topology in 3D 2. zigbee.tcl: network script written in tcl 3. thr_drop_delay.awk: eualuation script written in awk 4. data: results of delay, throughput, jitter, and packet loss rate 5. out: figures of results 6. demo: demos of nam 7. thesis How to 1. make sure zigbee.scn and zibee.tcl are in the same folder 2. cd to the folder by terminal 3. run ns zigbee.tcl 4. run awk -f thr_drop_delay.awk zigbee.tr 5. run gnuplot xxx.dat

一线显示,把电源跟数据线结合起来,减少了通讯连线.控制程序是C51的.(Line shows that the power supply combined with the data lines to reduce the communication connection. Control procedures are in C51.)
