基于8051单片机的模拟PS/2键盘的驱动程序，使用keil c51编译。

这是参加电子设计大赛时的作品：红外遥控小车：用红外线通过一块AT89S52单片机发射信号即编码，并用红外接收头接收信号；接着再用另一块AT89S52单片机对红外发射出的信号编码进行解码，最后再用一块AT89S52单片机用解码所得码值编写程序后驱动步进电机。步进机功能启动后不仅能使受控小车向前后左右四个方向前进和转弯，而且还能控制小车再地上转动并留下方形或圆形等形状。-This is the time to participate in Electronic Design Contest works: infrared remote control car: Using infrared transmission signal through an AT89S52 microcontroller that is encoded and used infrared receiver to receive the first signal and then using the other an infrared emitting MCU AT89S52 code and decode the signal and finally an AT89S52 microcontroller then proceeds with the decoding key value of the preparation of procedures to drive a stepper motor. Stepper machine function activated not only make the car forward in a controlled direction and after about four turns, but also to control the car and then turned and left the ground such as square or round shapes.

该程序为LED大型显示屏驱动程序，全部源代码为C语言编写-The program for the large LED display drivers, all the source code for the C language

利用 AT89S51 单片机的 P0 端口的 P0.0 － P0.7 连接到一个共阴数码管的 a － h 的笔段上，数码管的公共端接地。在数码管上循环显示 0 － 9 数字，时间间隔 0.2 秒。 -use AT89S51 SCM P0 port of P0.0- P0.7 connected to a digital control Yam were a-h of the pen, digital tube connected to the public. The digital display tube cycle 0-9 figures, the time interval of 0.2 seconds.

DS18b20的运用，有示例代码，绝对可以运用-DS18b20 the use of sample code there is, is absolutely entitled to exercise

单片机P1口与4个按键连接，用于信号幅度和频率调节操作键。单片机P0、P2.7、P3.6(-WR)与DA0832、2个741(运放)连接构成波形信号输出电路。 编程使波形信号输出电路输出正弦波信号，并且可通过操作键调节信号的幅度和频率。幅度和频率调节级别从0~10，共11个等级。 -Singlechip P1 I connect with the four buttons for the signal amplitude and frequency adjustment operation keys. Singlechip P0, P2.7, P3.6 (-WR) and DA0832, 2 months 741 (operational amplifier) to connect constitute waveform signal output circuit. Programming so that waveform signal output circuit output sine wave signal, and can be operated keys adjust the signal amplitude and frequency. Amplitude and frequency adjustment level from 0 ~ 10, a total of 11 grades.

有关液晶点阵的单片机程序，希望对初学者有一定的用处，大家看了就知道了。-the SCM process, and I hope to have some beginners use, we read will know.

atmega8的关于LED的代码，我自己写的，晶振是11.0592M的。-atmega8 on the LED code, I wrote it myself, crystal is the 11.0592M.
