ADXL345

AD0809的功能启动，描述了如何启动AD0809的数模转换功能，并且在旁边加油注释(The AD0809 s function is activated, and describes how to start the AD0809 digital to analog conversion function, and next to the fuel comment)

AD9850 AD 9851 并行 串行控制程序 很好的资料 以前自己花钱买的啊 (AD9850 AD 9851 serial parallel data control procedures well before the own money ah)

用普通遥控器做的电脑鼠标，遥控器发送数据，51单片机解码，通过串口发送到上位机上，在上位机上运行程序，实现鼠标控制(Do with an ordinary remote control computer mouse, the remote control to send data, 51 single-chip decoder, sent through the serial port to the PC, run the program on the host computer, mouse control)

使用51单片机，用其内部定时中断，和外部中断只找一个可控脉宽调制信号PWM(Using 51, with its internal timer interrupt, and external interrupt only to find a controllable pulse width modulation signal PWM)

超声波测距，可以通过串口助手显示，当小于设定值时，显示0，当大于设定值时，显示1(Ultrasonic Ranging, through serial aides showed that when less than the set value, 0, when greater than the set value, indicating a)

说明：  仿真机床切割,可生产可编辑的轨迹代码,方便操作.(Simulated machine tool cutting, can produce editable trajectory code, easy to operate.)

状态机按键检测，实现单击双击多击功能,单片机用的是STM8L(Key detection state machine to achieve multi-click-click, double-click function)

ds1302液晶时钟液晶时钟及温度检测程序(the ds1302 LCD Clock LCD Clock and temperature testing procedures)

用C语言编写的温度采集程序，可以用于C51单片机的开发(Temperature using C language acquisition program, can be used for C51 MCU development)

介绍了一种SPI从机的接口verilog编码(verilog code for spi slave )
