PIC18F2550 sorts of applications made ​ ​ with this beautiful project with 3 source code has comes up all the computer software and computer-related pic assembly software is written in Visual Basic 6

通过RS485端口不停地发送数据0xaa用示波器观察RS485端口A、B信号线上的波形或者用RS485接收器接收发送的字符。(Through the RS485 port to send data continuously 0xaa observed with an oscilloscope RS485 ports A, B signal waveforms or use the RS485 line receiver sends characters.)

利用单片机（STC89C52）为核心结合机械按键、数码管以及稳压器件等电子元器件组装了一个数字时钟，可以实现精准的计时以及修改等功能；(The combination of mechanical buttons, digital tube, and electronic regulator device the microcontroller (STC89C52) as the core components assembled a digital clock, and can achieve precise timing and modify functions )

说明：  该源码实现51单片机之间符合modbus通信协议的通信(This code can achieve communications between MCS51 by modbus protocol. )

msp430 ad9851 按键控制输出不同频率的正弦波已经调试成功(msp430 ad9851 keys to control the output frequency of the sine wave has been successful commissioning)

51单片机中的LCD12864显示,用的是C语言，为KEIL程序包。(51 microcontroller in LCD12864 display)

51单片机简单进行测试是否正常测试内容为LED灯等(51 single simple test whether the normal test content for the LED lights)

DDS9850，亲测可用，有中文解释，信号发生器(DDS9850, pro-test is available, there are Chinese explanation, the signal generator)

基于STM32的压力监控项目，配有2.8寸TFT显示屏，可以实时监控压力曲线，带有数据库功能(Based on the STM32 pressure monitoring project, with 2.8-inch TFT display, real-time monitoring of the pressure curve with database functions)

这是24L01开发头程序，希望对大家有帮阻(24L01 This is the first development process, we hope to help a resistance)
