利用89c51和8253可以测速，经初步测试可以通过

利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，实现主支路路口的交通信号灯控制（尽可能保持主线的畅通，即在通常情况下，保持主线的放行，只有在支线到达时，才放行支线），同时采用LCD显示倒计时时间及当前灯的状态。-The use of MCU timer timing, so that the crossroads at the traffic lights turn out light and to achieve the main slip road junction traffic lights control (as far as possible the smooth flow of the main line, that is, under normal circumstances, to maintain the release of the main line, and only arrived at the branch only when the release branch), while using LCD display countdown time and the current lighting condition.

基于CY7C68013A的mouse+keyboard混合USB外设应用范例。本套代码基于CY3684开发板，使用多个interface实现复合设备。与之相对的另一种方案是使用多个报表描述符，该方案另行上传。-This project focuses on building a mouse+ keyboard hybrid USB device with the popular Cypress CY7C68013A chip. Implementation is based on a multiple Interface solution. Please refer to CY3684 dev kit documentation for more details regarding hardware platform.

这是在51单片机上实现的完整功能的计算器源代码，用c写成，有利于帮助我们更好的学习单片机的开发-This is the 51 SCM achieve the functional integrity of the source code calculator, and c languages, will help us to better study the development of SCM

这个两个rar文件是关于定时器0使用的例子, 也是我第一次使用定时器0做的实验程序: 1. T0_ASM.rar, (带中文注释的C51语言例程), 利用定时器0中断实现LED灯的简单控制。 2. T0_C51.rar, (带中文注释的51汇编语言例程), 利用定时器0中断实现LED灯的简单控制。 两个同样功能的timer0中断程序都在MCU51-63K仿真器下通过实验, 小虾们可以试试看。 -Rar files that are both about the example of the use of Timer 0 is also the first to use my timer 0 of the experimental procedure to do: 1. T0_ASM.rar, (with English language routines C51 annotated), make use of the timer 0 interrupt implementation easy control of LED lights. 2. T0_C51.rar, (with English Notes 51 assembly language routines), use of the timer 0 interrupt achieve easy control of LED lights. Same function in both programs at timer0 interrupted MCU51-63K emulator through the experiment, shrimp can give it a try.

自制电路板FeCl3腐蚀控制器以PIC16F884为控制单片机，内带EEPROM，通过DS18B20和热电阻测温进而控制加热，加热最终温度可设且掉电存储，另外还有控制反应溶液流动电机，此以10秒为周期，流动时间按键可调；无按键10秒后实时显示溶液温度。-Self-made circuit board FeCl3 to control the corrosion controller PIC16F884 microcontroller, which with EEPROM, and thermal resistance through the DS18B20 thereby control the heating temperature, heating the final temperature can be set up and power-down store, in addition to control the flow of electric reaction solution, this 10 seconds cycle, flow time adjustable keys no real-time display button 10 seconds after the solution temperature.
