一份红外通讯的编码设计,已经经过实验，支持一对多。(Encoding of an infrared communication design, and after the experiment, to support one to many.)

opnet 仿真，陈敏老师2015年新书 opnet物联网仿真(opnet Simulation)

说明：  STM32F4开发指南-库函数版本_V1.1 STM32F4开发指南-寄存器版本_V1.1(STM32F4 Development Guide - Library Function Version _V1.1 STM32F4 Development Guide - Register Version _V1.1)

用数据库的方式操作excel文件，包括了读取文件的表名，字段名和数据，有详细的注释(Operate with the database excel documents, including a table read from the file name, field names and data have detailed notes)

C++编程实现的PLC梯形图编程环境，很不错(C++ programming of PLC ladder programming environment, very good)

描述了S57标准国际电子海图的数据格式的详细说明(S57 standard describes the data format of international electronic chart)

STM32学习版定时器控制，里面包含解释说明，以及引脚配置(STM32 timer control)

1．EMIF 接口 TMS320F28335DSP 的扩展存储器接口(EMIF)用来与大多数外围设备进行连接，典型应用 如 连接片外扩展存储器等。这一接口提供地址连线、数据连线和一组控制线。ICETEK–F28335-A 将这些扩展线引到了板上的扩展插座上供扩展使用。 2．液晶显示模块的访问、控制是由28335ADSP 对扩展接口的操作完成。 控制口的寻址：命令控制接口的地址为 0x208001，数据控制接口的地址为0x208003 和 0x208004，辅助控制接口的地址为0x208002。 3．显示控制方法： -液晶显示模块中有两片显示缓冲存储器，分别对应屏幕显示的象素，向其中写入数值将改 变显示，写入“1”则显示一点，写入“0”则不显示。(The 1.EMIF interface Extended TMS320F28335DSP memory interface (EMIF) is used to connect with the most peripheral equipment, typical application Such as The connecting piece of extended memory. This interface provides the address lines, data lines and a set of control line. ICETEK- F28335-A The extension line to the extension socket for plate on the expansion of the use of. 2 liquid crystal display module access, control by the 28335ADSP to the extended interface operation is complete. Addressing control port: Command and control interface address 0x208001, the address data control interface for 0x208003 and 0x208004, auxiliary control interface address for 0x208002. 3 display control method: - liquid crystal display module with two display buffer memory, respectively corresponding screen pixel, writing values will be changed to the Change display, write "1" shows a little, write "0" are not displayed.)
