利用PC机的硬件定时8253, 编制秒表延时(0~9秒)程序.要求: 按任意键,开始计时, 在屏幕上以1秒间隔从0到9显示 按ESC键,计时停止.-use of PC hardware-timed 8253, the establishment of a stopwatch Delay (0 ~ 9 seconds) program. Requirements : by the arbitrary button, the timer on screen to a second interval from 0 to 9 shows by the ESC key, a time to stop.

一个与一个低通滤波器结合可以用作简单、廉价的数/模转换器。其输出可用于驱动电压控制器件，或用于需要模/数转换器采样受控参数的反馈控制系统中。PWM常用于电机控制系统中。-A combination of a low-pass filter can be used as a simple, low-cost D/A converter. The output can be used to drive voltage control devices, or for the need for A/D converter sampling the controlled parameters of feedback control systems. PWM motor control commonly used in the system.

用PIC16C54来实现汽车空调的动作控制（扫风、除霜、点火、循环扫风。。。），因16C54内存较小，故采用汇编来实现，其中的定时编程，颇费了我一番心思，希可供借签！-Using PIC16C54 to achieve motion control in vehicle air-conditioners (sweep wind, defrost, ignition, cycle the wind sweep 。。。), due to the smaller memory 16C54, it used to realize a compilation, of which the regular programming, a lot of my remarks thinking, by signing for Greek!
