Simple ptxdist create program

控制小车的寻迹，避障，刹车等功能，算法较为简单，基本以驱动电机为主(Control of the car tracing, obstacle avoidance, braking and other functions, the algorithm is simpler, basic to the main drive motor)

SMSC公司USB3300芯片评估板原理图、datasheet、STM32代码(SMSC corp s USB3300 chip sch, datasheet and sourcecode for STM32 MCU)

基于STM32开发板，通过模拟寄存器，验证I2C通信功能，(I2C_TwoBoards_ComPolling I2C Two Boards Communication Polling Example)

共5个文件。2个描述了一些时钟的初始化以及时钟的使用。2个描述了UART的使用。一个文件是一个简单的使用示例。(This zip file contains the simple code to control the stm32 components. It tells how to initialize the clock module, use the clock module, and how to do the same thing to UART.)

LPC1788基础工程文档，特别干净，目录设计合理，结构清晰，非常合适在此基础上开始增加自己的代码。已在此基础上完成几个项目的开发！！！(LPC1788-based engineering documentation, especially clean, catalog rational design, clear structure, very appropriate on this basis, began to increase their own code. Has completed the development of several projects based on this! ! !)

说明：  自己写的基于GPS的通讯倒计时程序。可以直接使用，按键调整时间。希望对初学者有所帮助(The base of GPS communication count time program, maybe help the first person in this project. the key can adjust the time.)

STM8单片机的SPI主从通信，一个STM8单片机当主机，另一个STM8单片机当从机，基本实现了SPI的所有功能，特别适合对SPI的深入理解。(STM8 microcontroller SPI master or slave communication, a STM8 microcontroller as host another STM8 microcontroller from the machine, the basic realization of all the features of the SPI, especially for in-depth understanding of the SPI.)

C++ 编写的string类库，并实现string的各项函数操作。(string function)

介绍了一种精度很高的AD采集芯片，很高的采集速度和很高的精度(Introduces a high precision of the AD acquisition chip, high acquisition speed and high precision)
