The advantages of ease of use, and is fully patible with all the features of MCS5l series of microcontrollers. AT89C51 is a kind of 4K bytes of flash erasable programmable readonly memory (FPEROMFAlsh ProgrAmmABle And ErAsABle ReAd Only Memory) of the lowvoltage, highperformance CMOS8bit microprocessors, monly known as microcontrollers. The device uses highdensity nonvolatile memory ATMEL manufacturing technology manufacturing, and industrystandard MCS51 instruction set and output pins are patible. Owing to the multifunction 8bit CPU and flash memory bined in a single chip, ATMEL The AT89C51 is a highly effective microcontrollers, embedded control systems for many provides a high degree of flexibility and low cost programs 指 導 教 師 評 語 外文翻譯成績：指導教師簽字： 年 月 日注：1. 指導教師對譯文進行評閱時應(yīng)注意以下幾個方面：①翻譯的外文文獻與畢業(yè)設(shè)計（論文）的主題是否高度相關(guān)，并作為外文參考文獻列入畢業(yè)設(shè)計（論文）的參考文獻；②翻譯的外文文獻字數(shù)是否達到規(guī)定數(shù)量（3 000字以上）；③譯文語言是否準確、通順、具有參考價值。 the same time, by controlling the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed.Details of stepper motor speed control principle Stepper motor speed control in general is to change the input frequency of stepper motor pulses to achieve the stepper motor speed, because the stepper motor to a pulse on each rotation a fixed point of view, so that you can by controlling the stepper motor a pulse to the next a pulse time interval to change the pulse frequency, the length of delay to specific controls to change the angle stepper motor speed, in order to achieve stepspeed power. A specific delay time can be achieved through software. This requires use of SCM acceleration and deceleration of the stepper motor control, in fact, to change the output pulse time interval, microcontrollercontrolled stepper motor enables operation of addition and subtraction methods are two kinds of software and hardware and software methods that is attributable mainly to delay proceedings to change the pulse output frequency, in which the length of delay is dynamic, the software method in motor control, we must const
