基于51单片机的电子密码锁设计，完整的文档。(Based on 51 single-chip electronic code lock design, complete documentation.)

第一章开关电源设计的一般考虑 在设计开关电源之前，应当仔细研究要设计的电源技术要求。现以一个通信电源模块的例子来说 明设计要考虑的问题。该模块的技术规范如下(The first chapter is generally considered switching power supply design before switching power supply design, should carefully study the technical requirements to design power. Now with a communication power module design examples to illustrate the problem to be considered. Technical specifications of the module are as follows)

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.)

用于模块化多电平逆变器最低电平调制程序,很好的控制方法(Minimum level modulation program for modular multilevel inverters)

stm32单片机全功能bootloader，包括SD，串口，网口，和USB。选择条件编译(stm32 SCM fully functional bootloader, including SD, serial port, Ethernet port, and USB. Select conditional compilation)

姿态传感器又称为方向传感器，主要感应手机方位的变化，每次读取静态状态值。该代码可以读出分别沿3个轴所转过的角度(The attitude sensors also known as the direction sensor, sensing changes in the orientation of the phone, every time you read the static state value. The code can be read out respectively along the three axes are rotated by the angle)

基于KEIL C51和MC55模块的短消息发送和接收程序源代码,C51控制，AT命令实现(based KEIL C51 and MC55 module of SMS sending and receiving the source code, C51 control, AT commands)
