First, the general introduction:Stepping motor is an open-loop control element stepping electric part which transforms electric pulse signal into angular displacement or line displacement. In the case of non-overloading, the speed of the motor, the position of the stop only depends on the frequency of the pulse signal and the number of pulses, and is not affected by the load changes, when the stepper driver receives a pulse signal, it will drive the stepper motor in the direction set to rotate a

application interface (API) for HTML and XML. The DOM will plan the entire page into a document composed of node hierarchies. Each part of the HTML or XML page is a derivative of a node, and the DOM API makes it easy to delete, add, and replace nodes. Through this mechanism, we have unprecedented control over the content and structure of the document, which greatly improves the interactive ability of the page.
