仿真电话键盘拨号的电路图 C 以及HEX文件 是我的单片机考试作业(this is my master piece)

zigbee cc2530无线数据接受与发送，以外接传感器MQ-2酒精传感器为例，内置协议栈，直接下载就行，IAR版本为8.1(zigbee cc2530 wireless data accepted and sent to the external sensor MQ-2 alcohol sensor, for example, the built-in protocol stack, the direct download on the line)

使用MSP430操作12864显示屏，共显示四行。可显示中文汉字(Use MSP430 operation 12864 display four lines total. Can display Chinese characters)

实现ADT7310温度采集并传输到M25P16上存储(Achieve ADT7310 temperature acquisition and transfer to the storage on the M25P16)

stm32下跑通usb外设，编译环境基于keil(stm32 next run through usb peripherals, based on keil compiler environment)

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.

STM32单片机开发例程，这里是外部中断的开发例程(STM32 MCU development routines, here is the development of the external interrupt routine)

32位单精度浮点数的乘加运算的C编程，感兴趣的可以看一下(Single-precision floating-point multiply-add operation of the C programming, interested can look at)

基于DS18B20+DS1302+lcd1602+MSP430的温度时间综合测量(temperature and time measurement based on MSP430,DS1302,DS18B20,LCD1602)

简单的音乐盒，可以播放音乐，并且有花样灯进行闪烁，是个不错的小礼物。(music box )
