可以自己制作U盘 SM2246EN_tu

主要用于测试SIM300CZ拨打电话和MT8870程序,已测(Mainly used for testing SIM300CZ call and MT8870 procedures have been measured)

24C256的C51程序 包括IIC程序(24C256 IIC procedures, including procedures for the C51)

简单的小程序简单的小程序简单的小程序简单的小程序(Simple small programSimple small programSimple small programSimple small program)

说明：  工业以太网现场总线EtherCAT及驱动程序设计的论文，共大家学习和参考(The thesis of industrial Ethernet Fieldbus EtherCAT and driver design is for your reference)

采用MSP430单片机控制VS1003芯片进行MP3播放， MSP430通过读取 SD 卡里面的MP3歌曲，将数据发往VS1003进行解码，然后通过音频输出进行播放。(VS1003 using MSP430 MCU control chip MP3 player, MSP430 by reading the SD card inside the MP3 songs, the data will be sent to the VS1003 is decoded and then played through the audio output.)

该模块实现串口DMA发送中断接收，与系统或者外设通信，一发一答的方式，发送一帧数据，需等待对方应答，如果在规定时间内未等到ACK数据，发送端 会重发该数据，采用状态机制原理，对串口使用以及协议搭建很参考价值(The module DMA send serial interrupt receiving, and system or peripheral communication, one answer, send a frame of data, need to wait for the answer, if ACK did not wait until the data within the specified time, the sender will retransmit the data, using the state mechanism principle, build a reference value for the use of serial port and protocol)

说明：  这是基于开发板LPC1114的源码程序，是用C语言编写，关于液晶显示屏的配置和实现同时它也是一个完整的模板，可以在此基础上添加其他程序用于开发板的学习，是一个完整的模板，可直接使用。(This is based on the development board LPC1114 source code program, is written in C language, on the LCD display configuration and implementation at the same time it is a complete template, you can add other programs on this basis for the development board learning, is a complete template, can be used directly.)

使用stm32cubemx生成代码,驱动ds1302 采用突发模式读写时间和寄存器(Use stm32cubemx to generate code that drives the DS1302 to use burst mode read and write time and registers)

通过STM32单片机采集ADC的数值，然后通过串口传送给上位机进行接收()

这个一个关于储能电池充放的仿真，电路采用了DC_DC变换控制。(The storage battery charge and discharge about simulation, the circuit uses DC_DC conversion control)
