STM32F103控制继电器输出，可扩展应用至其他程序(STM32F103 Control Relay Output)

spi协议，分为几个文件块，以供调用，采用时钟芯片ds1302做例子，进行协议的实现，是c程序方面阅读。(spi agreement, the document is divided into several blocks, calling for the use ds1302 clock chip as an example, for the realization of the agreement is c procedures reading.)

说明：  stm32+esp8266实现远程控制功能(Using WiFi to realize remote control function)

这是mso430f5529最小系统原理图(This is the schematic diagram of the minimum system of mso430f5529.)

39SF040读写操作，使用KEIL开发环境编译，此程序已测试通过。(39SF040 read and write operations, using the KEIL compiler development environment, this program has been tested.)

8个单片机小程序，对串口、中断的学习很好理解。(8 SCM applet, the serial interrupt learning well understood.)

单片机通过ADC0832在lcd1602显示电压数值。(The single chip computer displays the voltage value in LCD1602 by ADC0832.)

high speed pcb design spicification, the book is very useful.

说明：  MPU6050通过STM32F429发送数据到上位机。或是通过显示屏显示。(MPU6050 sends data to PC through STM32F429. Or display it on a screen.)

基于51单片机的32和弦音乐盒程序，有曲目切换，音量调节，播放时间，步进电机驱动，流水灯等功能，是普通音乐的升级版本，且代码清晰，注释完整，结构合理。(Based on 51 single-chip 32 polyphonic music box procedures, switch tracks, adjust volume, play time, stepper motor drive, water lights and other functions, is an upgraded version of the ordinary music and clear code, comments, integrity, reasonable structure.)
