这篇程序是我一个同学编的,并且已经应用到了二相步进电机(四线步进电机)上了.但是我认为此程序需要改进的地方有很多....

美国TI公司的protel 元器件库，在应用中需要更新，本人收集了最新的版本共30M，为提高上传速度分六次上传。文件名依次为TI_1到TI_6。希望大家设计电路板时少走弯路 以下是TI_5-TI" s U.S. Treasury protel components, need to be updated in the application, I collected a total of up-to-date version of 30M, to improve the upload speed upload six hours. File name followed by TI_1 to TI_6. Hope that the design of circuit board is less detours following TI_5

There are many different (and often confusing) terms associated with clock-based devices. This application note attempts to clarify these terms, and hence serves as a comprehensive reference on clock terminology. This application note can be divided into two sections. The first section describes and distinguishes between various clock sources available today. The second section defines and distinguishes between various parameters used to describe clocks. This section also provides methods of measuring some of these parameters.
