本实验实现PS/2接口与RS-232接口的数据传输， PS/2键盘上按下按键，可以通过RS-232自动传送到主机的串口调试终端上（sscom32.exe）； 并在数据接收区显示接收到的字符。 串口调试终端的设置：波特率115200，一个停止位，无校验位。 -Realize this experiment, PS/2 interface with RS-232 data interface, PS/2 keyboard to press the button, through RS-232 automatic transmission to the host serial debug terminal (sscom32.exe) and data receiving display received characters. Serial debug terminal settings: 115200 baud rate, one stop bit, no parity bit.

这是一个简单的pid控制程序，用的是增量式pid控制，在智能车上使用的。-This is a simple pid control procedures, using the incremental pid control, used in the smart car.

这是个火车传感器的小程序，在某车厢里存放N个传感器，当某个传感器温度超过或者低于某个指定范围，系统发出警告。-This is a small sensor train procedures, in a vehicle storage N sensors, When a sensor temperature is over or below a certain designated areas, the system issued a warning.

HT1621的驱动文件。对用于测试段码液晶比较有用。程序部分参考了别人。-HT1621 driver file. Paragraph for testing code on the LCD more useful. Program is partly based on other people.
