本文以第一视角讲述了移植FATFS文件系统的过程。其中遇到的困难，解决方案的寻找，原理的讲解，都能带给人许多启发(This paper describes the process of transplanting FATFS file system from the first perspective. The difficulties encountered, the search for solutions, and the explanation of the principles can give people a lot of inspiration.)

说明：  基于zigbee开发 CC2530的直流电机控制(Development of DC Motor Control Based on Zigbee CC2530)

实现ti公司的tm4c1294的板载硬件can通信(Realization of on-board hardware can communication of tm4c1294 of TI company)

1、学习目的：利用定时器产生PWM，了解原理和使用方法 2、硬件要求：直流电机 定时器 3、试验现象：按键调速，PWM部分显示速度档位，电机根据档位调节速度 这个需要把电机驱动输入端和PWM端连接起来(1 Learning Objectives: To use the timer to generate PWM, to understand the principles and use, hardware requirements: DC Timer 3, the experimental phenomenon: button speed control, the PWM section shows speed gear, the motor stalls adjust the speed the motor drive input and PWM connect)

多功能计算器的完整源代码，能实现常用的数学计算。(The complete source code of the multi-function calculator, used mathematical calculations.)

msp430f5529和nokia5110显示字符(Msp430f5529 and Nokia 5110 display characters)

说明：  斯凯mrp开发用的宽字符转换 很有用的 有个头文string.c 和string.h 头文件里有定义(Sky mrp convert wide character to use for development of a useful article string.c head and string.h header files are defined)

本设计已STC89C52RC单片机为基础，HS0038B为一体化红外接收头，恒流驱动采用的AMC7135芯片的红外控制全彩灯（1w的RGB-LED），程序中使用的遥控器用户码和编码和系统电路图已在文件里给出，每一部分已经分别进行注释方便大家理解，因PROTEUS不方便红外仿真所以不再提供仿真模型，由电路图可直接制作实物。(This design has been based on STC89C52RC MCU, HS0038B for integrated infrared receiving head, constant current driver using AMC7135 chip infrared control all the lights (1 w RGB LED), the program used in the user code and code and remote control system circuit diagram has been given in the file, each part has annotated facilitate everybody understand respectively, because of PROTEUS inconvenient infrared simulation, so no longer provide simulation model made physical circuit diagram directly. )
