说明：  51单片机控制GSM模块发短信和打电话的C源码(GSM single-chip control module 51 send text messages and phone calls the C source)

气体传感器采样与无线数据传输并发送至电脑 cc2530,多通道数据传输，IAR版本为8.1(Gas sensor sampling and wireless data transmission and sent to the computer cc2530, multi-channel data transmission, IAR version 8.1)

超声波测距模块扩展实验，使用超声波传感器，把数据结果显示在1602上。(Ultrasonic Ranging Module extension experiments using ultrasonic sensors, and display data results in 1602.)

For this project you need a 3.7v power supply that prepared by LM317 regulator. So you need MAX232 for connect uart to pc .my AVR chip project is Mega8 that you can program on any Avr chip have 2kbyte rom. In bascom spi hardware don’t work correct, so I have to software spi ,but the software spi configure have low speed into hardware spi.

PN532的上位机软件库，包括应用说明文档(PN532 PC software libraries, including the application documentation)

说明：  单片机c语言 初学者有用 有例子哦 (SCM c language for beginners there are examples of useful oh)

正弦信号发生程序。使用声卡产生正弦信号输出，可以用来调音！(Sinusoidal signal procedures. Sinusoidal signal generated using the sound card output, can be used to tuning!)

通过单片机输入程序来对步进电机进行控制，以此实现一定功能。(Stepping motor single chip microcomputer)

简单的基于CC2530的ZigBee监控上位机(A simple ZigBee console basic on CC2530)

采用TI LaunchPad开发板触摸屏控制DAC7611输出电压(TI LaunchPad development board using the touch screen controls DAC7611 output voltage)
