keilc51中stc芯片补丁，用于stc系列芯片的开发

用５１单片机读取ＣＦ卡的程序。对许多项目有参考价值-51 microcontroller with CF card reader procedures. Many of the projects to be a valuable reference

上车按键后开始计价。有实时时钟、单价、距离和总价钱显示。可以通过键盘修改单价（元/公里）和时间。有清除键用以清楚上次费用。利用LCD分别显示时间、单价、路程和费用。LED辅助显示说做操作。-Button on the bus after the valuation. Real-time clock, unit price, distance, and the total price display. You can modify the keyboard unit price (yuan/km) and time. There is the clear key to clear the last cost. Respectively, using LCD displays time, price, distance and cost. LED auxiliary display saying that operation.

读51按键，并将ascii码返回计算机串口调试助手，-Read 51 keys, and return the computer serial port debugging assistant

一个用ATMega88来实现一key键和一个Rotor的代码，可能过UART上传数据。-A key with ATMega88 to achieve a key and a Rotor code, may be to UART upload data.

单片机扩展是单片机应用的重要部分，文档主要介绍单片机的片外扩展。-extantion of msc51

基于avr单片机的74hc164并入串出显示的仿真(proteus,c源码) -Avr microcontroller based on a displayed string 74hc164 into the simulation (proteus, c source code)

1.8个流水灯先会从上到下流动一遍，同时蜂鸣器发声。 2.接着DAC电流指示灯由暗变亮 3.接着前三位数码管显示温度值 4.接着AD数值显示在数码管的前三位-1.8 water flows from top to bottom lights will be again, at the same time audible buzzer. 2. And then the current DAC become bright light from the dark 3. And then the top three digital temperature display 4. Then AD numerical display of the top three in the digital control

控制直流电机的c程序，大家看一下，做下点评，-C DC motor control procedures, look at everybody, to do under the comments,
