This is a photo of a general purpose timer/ 在我们写的程序当中,总有一些配置信息需要保存下来,以便完成程序的功能,最简单的办法就是将这些信息写入INI文件中,程序初始化时再读入.具体应用如下:counter card you can wirewrap in a weekend. It plugs into your PC s ISA bus just like a sound or modem card. It gives high-resolution timing (microseconds). Because of its programmablity, it is very powerful and flexible. You can even control DC or servo motors using pulse-width modulated (PWM), or stepper motors using its square wave capabilities. The figure below is the actual output (square wave) from the 8254 card captured by an oscilloscope: -This a photo of a general purpose timer. When we write program, There is always some configuration need to be saved, so that we can finish the function of the program.The most simple way is write these infomation to the INI file. It is read by the program during initialization,it is used as follows: counter card you can wirewrap in a weekend. It plugs into your PC s ISA bus just like a sound or modem card.
