PIC 16F628 + L6219 在微步模式下步进控制

在微型计算机系统中, CPU与外部的基本通信方式有两种,一种是并行通信即数据的各位同 时传送,其优点是传输速度较快,但数据有多少位就需要多少条传送线 而串行通信中数据一位一位顺序传 送,能节省传送线. 用Verilog HDL语言实现了串并、并串通信接口之间的转换-In the micro-computer system, CPU and the outside of the basic means of communication there are two types of parallel data communication that is transmitted at the same time you have the advantage of faster transfer speeds, but data on the number of those who need the number of transmission line and string A line of data communications, a sequence of transmission, transmission lines can be saved. using Verilog HDL language and realize the string, and string conversions between the communication interface

滑动控件是Windows中最常用的控件之一。一般而言它是由一个滑动条，一个滑块和可选的刻度组成，用户可以通过移动滑块在相应的控件中显示对应的值。通常，在滑动控件附近一定有标签控件或编辑框控件，用于显示相应的值。滑动控件在应用程序中用途级为广泛，如在桌面的属性中就可以看到。为此，让我们一起来看一下它的实现方法。-Sliding Windows Control is the most commonly used one of the controls. Generally it is a sliding strip, a slider and the optional calibration components, The user can move the slider in the corresponding controls showed the corresponding value. Usually, in the vicinity of the sliding controls must be labeled control or editorial control box for a corresponding value. Sliding controls in the application process for the wide-use, as in the desktop properties can see. To this end, let us look at the method of achieving it.
