SD卡2.0协议

运动控制卡的详细开发资料，可以用来驱动步进电机(Motion control card developed detailed information can be used to drive stepper motor)

STC12C5A60S2 IIC读取EEPROM：I2C读取E2PROM(STC12C5A60S2 IIC reading EEPROM: I2C read E2PROM)

笔记本键盘测试程序，可以测试键盘按键是否有作用。(Notebook keyboard test program.)

可以产生幅度、频率可调的方波，频率50hz到1M(Can produce the amplitude, frequency adjustable Fang Bo, frequency of 50Hz to 1M)

MEGA8的PWM输出功能来完成三路PWM波形.doc(MEGA8 PWM output function to complete the three-way PWM waveform. Doc)

该夜用照明灯系统采用AT89S52单片机为核心，利用单片机的端口分别控制LCD1602标准时钟系统、可控硅和电铃，达到智能操控照明系统(The night with the lighting system using AT89S52 microcontroller as the core, using SCM port control the LCD1602 standard clock system, SCR and bells, to the intelligent control lighting system)

这是有关pwm的控制，可以控制它周期的长短来控制灯的亮度，还可以控制它自动调光。(This is the control of the pwm, the length of the cycle it can be controlled to control the brightness of the lights can also control the automatic dimming.)

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)
