adc转换器，实现ad转换功能，可以进行自己的小项目设计

利用51单片机来实现航标灯的控制，使用定时器来控制二极管的发光，可以模拟水上航标灯的功能，实现对过往船只的航向指引！-The use of 51 single-chip to achieve the control of aids to navigation lights, the use of timers to control the light-emitting diode, can simulate the function of water navigation lights, the achievement of passing ships on the guidelines of course!

用8051单片机 DS18B20显示是用LED,单片机用AT89S52. 做的温度控制系统-With the 8051 DS18B20 display is used LED, Microcontroller with AT89S52. To do temperature control system

51单片机的电子琴C程序有自动演奏和键盘演奏功能-51 Microcontroller, the flower C program for automatic playing and keyboard performance features

大值的驱动电压，否则会造成液晶模块的损坏。如果在低于或大致等于典型驱动电压时，观察到了显示屏上有色调的变化，即显示域的底色略深于边缘的颜色，表明液晶模块电源连接正确，可以进人下一步工作。如-Large value of driving voltage, otherwise LCD module can cause damage. If less than or roughly equivalent to a typical drive voltage, the observed screen has color changes, which indicates that the domain a little deep background color at the edges, indicating that the LCD module power supply connections are correct, you can enter the next step. Such as

功能： 1、作为主机通讯采集两路下位机数据并将此数据通过8255送出（十路水位值） 并计算水头送STC板 2、采集数据为BCD码制，先转换成二进制，处理后再转换成BCD 3、通讯采用方式3，多机通讯，上位机发地址时TB8=1，其他TB8=0 下位机SM2=1，RB8=1时产生中断后使SM2=0收发数据，结束后SM2=1 在此系统中本机硬件地址要设为0-Features: 1, as the host of two-way communication acquisition of data-bit machine and send this data through 8255 (the road level 10 value) and calculate the head sent to STC board 2, for BCD code data collection system, the first converted into binary, and then deal with the conversion into BCD 3, communication using methods 3, multi-machine communications, address PC made TB8 = 1, other TB8 = 0 under the digital machine SM2 = 1, RB8 = 1 when the failure to make SM2 = 0 to send and receive data, after the end of SM2 = 1 in this system to the local hardware address set to 0

Verilog实现的DDS正弦信号发生器和测频测相模块，DDS模块可产生两路频率和相位差均可预置调整的值正弦波，频率范围为20Hz-5MHz，相位范围为0°-359°，测量的数据通过引脚传输给单片机，单片机进行计算和显示。-Verilog realize the DDS sine wave signal generator and frequency measurement module test phase, DDS module can generate both frequency and phase difference can be preset to adjust the value of sine wave, frequency range of 20Hz-5MHz, phase range of 0 °-359 ° , measurement data and transmit them to the single-chip pin, single-chip microcomputer to calculate and display.
