本系统基于反馈控制思想,由交直流转换电路、DC-DC变换器、步进电路模块和显示模块4个模块电路构成开关稳压电源。交直流转换电路整流部分采用全波桥式整流电路形式,DC-DC变换器以TL494有主核心设计并加上简单滤波电路及RC放电回路所构成的回路控制器。它能把脉冲宽度变化的信号转换成与脉冲宽度成正比变化的直流信号,进而实现闭环单回路控制。由单片机控制
数字定位器X9241的电阻,进而控制输出电压。显示模块由LCD1602构成。
(Based on feedback control of the system of thought, from AC-DC converter circuit, DC-DC converters, stepper circuit module and display module 4 module circuit switching power supply. AC-DC converter circuit using full-wave rectifier part of the circuit form of bridge rectifier, DC-DC converter to TL494 have the main core of the design and add a simple RC filter circuit and discharge circuit posed by the loop controller. It can change the pulse width signals into changes with the pulse width is proportional to the DC signal, and thus realize the closed-loop single-loop control. By the single-chip microcomputer to control the number of locator X9241 resistance, thereby control the output voltage. LCD1602 constituted by the display module.)

该程序是本人用AVR ATtiny13写的的一个只用4个IO口驱动两相四线制步进电机的程序,还可以控制转动的上下限(祥见程序屏蔽部分)对使用两相四线步进电机的初学者来说无疑是一笔珍贵的学习资源,对要求以最低成本驱动两相四线步进电机的使用者来说,更是提供了一个有利的参考。推荐!(I use the program is written in AVR ATtiny13 a four IO only I drive two-phase four-wire stepper motor program, but also can control the rotation of the upper and lower limits (祥见shielding part of the procedure) on the use of two-phase four-step beginners into the motor is undoubtedly a valuable learning resource for the lowest cost drive requires two-phase four-wire stepper motor users are provided a favorable reference. Recommended!)
