嗨，我正在工作的步进电机完全旋转360度，每分钟150转。我已经和马达司机接口了。我需要在一个位置上启动和停止马达，比如说180度。我怎样才能做到这一点，请帮助我作为一个新的，这不是我的想法。截至目前，电机连续旋转360度。
以上来自于百度翻译 以下为原文 Hi , Am working on Stepper Motor which rotates completely 360 deg with 150 RPM . I have interfaced with motor driver . I need to start and stop the motor at one position say at 180 deg . How can i achieve this please help me as am new to this am not getting idea. As of now am rotating the motor continuously 360 deg.

你是说你用马达驱动IC来驱动马达？哪一个？

这只是一个拨号H桥驱动芯片，所以它需要PIC来产生步进波形。你的意思是你已经有PIC产生波形使马达旋转了吗？如果你只是施加一个直流电压，它是旋转的，那么它不是步进电机。
以上来自于百度翻译 以下为原文 That is just a dial H bridge driver chip, so it requires the PIC to generate the stepping waveform. Do you mean you already have the PIC generating the waveform to make the motor rotate? If you're just applying a DC voltage, and it is rotating, then it is not stepper motor. |

我写了一段代码，它旋转。但我需要启动电机在一点，停止电机在同一点，当我给一个脉冲。
以上来自于百度翻译 以下为原文 I wrote a piece of code its rotating .. but i need to start motor at one point and stop motor at the same point when i give one pulse.. |

您想显示您编写的代码吗？如果你给马达“一个脉冲”，那么它只能移动一步。正如我所说的，如果你只是用一个方法来激励它，它就继续运动，那么它就不是步进电机。
以上来自于百度翻译 以下为原文 Would you like to show the code you have written? If you give the motor "one pulse", then it should move only one step. As I said, if you are just energising it one way, and it keeps moving, then it is not a stepper motor. |

步进电机通常被设计成一个完整的循环，例如四个简单的步骤，是实际旋转的60度。这是因为他们设计的磁铁排列在花键上。在HTTPS://Youtu.BE/MHDZ3C6KLRG和HTTPS://Youtu.BE/T-3VNLADBC上可以找到解释步进电机如何工作的视频。
以上来自于百度翻译 以下为原文 Stepper motors are often designed so that a complete cycle, say four simple steps, is 60 degrees of actual rotation. This is because they design the magnets to line up on splines. Videos on explaining how stepper motors work can be found at https://youtu.be/MHdz3c6KLrg and https://youtu.be/t-3VnLadIbc . |

这是一个开始。你测试过一个完整的旋转需要多少个周期吗？A1、B1、A2和B2是如何定义的？正如ChanZIa所提到的，你使用的PIC也是相关的。
以上来自于百度翻译 以下为原文 That is a start. Have you tested how many cycles like this you need for a complete rotation? How EXACTLY are A1, B1, A2, and B2 defined? As Cinzia mentioned, which PIC you are using is also relevant. |

你需要看一下电机的数据表。你需要找到每一步的度数，固件中的步长为180度。
以上来自于百度翻译 以下为原文 You need to look at the data sheet for the motor. You need to find the degrees per step, and the in the firmware count the number of steps for 180 degrees |

感谢您的答复，电机规格-步进电机步进角- 1.8度每步＝200旋转码-空（）{TrISC0＝0；TrISC1＝0；TrISC2＝0；TrISC3＝0；而（1）{A1= ON；B2= OFF；A2＝OFF；B2＝OFF；α-DelayyMS（1）；A1= ON；B1= ON；A2= OFF；B2= OFF；γ-延迟。Ay= MS；（1）；A2= On；B2= OFF；A1= OFF；B2= ON；B2= OFF；A1＝DelayyMs（1）；A1= OFF；B2= ON；B2= ON；B2＝On；A1= OFF；B1= OFF；A2= OFF；B2= ON；α-DelayyMs（1）；A1= ON；B1= OFF；A2= OFF；B2= ON；B2= ON；αMS（1）；A1= OFF；B1= ON；A2= OFF；B2= OFF；LaysMMS（1）；} AM使用PIC16F87A控制器和XC8编译器。我与马达连接了一个驱动器和一个磁传感器连接到马达。一旦我得到一个触发器，我的马达就应该在固定位置开始旋转一个完整的周期，并以相同的位置结束它的启动。

I have connected motor with driver and one magnetic sensor connected to motor . As soon as i get one trigger my motor should start at fixed position rotates complete one cycle and end it with same position where it started. |

好的，你回答了我的一个问题，但是忽略了“A1，A2，B1，B2定义”的问题。我可以猜测看你的代码，但我不需要。我猜你有磁性传感器连接到另一个PIC管脚。哪一个？这个“扳机”是什么？另一个PIC PIN？你必须使用PIC16F87A吗？这确实是一个古老的芯片，当试图同时改变同一个端口上的多个引脚时，需要非常小心。PIN兼容的PIC16F1XXX设备更便宜，更容易使用，并且没有16F87A的问题。
以上来自于百度翻译 以下为原文 ok, you answered one of my questions, but ignored the "how are A1, A2, B1, B2 defined" question. I can probably guess looking at your code, but I shouldn't have to. I guess you have the magnetic sensor connected to another PIC pin. Which one? What is this "trigger"? Another PIC pin? Do you have to use a PIC16F877A? That really is an ancient chip, and requires great care when trying to change multiple pins on the same port all at once. There are pin compatible PIC16F1xxx devices available that are cheaper, easier to use, and don't have the problems that the 16F877A does. |

我强烈建议您一次一个地写入POTC，而不是一个引脚，以避免在没有LAT寄存器的情况下在PICS上进行读写修改问题。您可以写入整个端口，因为如果写入PIN为输入，则无所谓。01；//A1= ON；B1= OFF；A2= OFF；B2= OFF；A1= ON；B1= ON；A2= OFF；B2= OFF；SimePosic＝0B0101；//A1= ON；B1= ON；A2= OFF；B2= OFF；等等。
以上来自于百度翻译 以下为原文 I would strongly advise you to write PORTC all in one instruction, not one pin at a time, to avoid read-modify-write problems on PICs without LAT registers. You can write the whole port, as it does not matter if you write to pins set as inputs. So A1 =ON; B1= OFF; A2 =OFF; B2= OFF; becomes PORTC = 0b0001; //A1 =ON; B1= OFF; A2 =OFF; B2= OFF; A1 =ON; B1= ON; A2 =OFF; B2= OFF; becomes PORTC = 0b0101; //A1 =ON; B1= ON; A2 =OFF; B2= OFF; and so on. |

当你指的是高和低时，使用和关闭是令人困惑的。L29 8N既能提供电流，又能吸收电流，因此，基本上对两对电机绕组施加两种不同的极性。如果设置B1和B2低，它将基本上缩短绕组，这可以用作制动器。这里有一篇文章介绍了使用ARDUION:http://www.指导表……的L29 8N。电机B真值表3BIN 4IN描述符0N/AN/AMotor B是OF100B电机停止（制动器）101电机B打开，后转110电机B打开，转转11B电机停止（制动器），来自http://www. BANANAROBOICTIC…-H桥式电动驱动器
以上来自于百度翻译 以下为原文 It is confusing to use ON and OFF when you probably mean HIGH and LOW. The L298N can both source and sink current, so you are basically applying two different polarities to each pair of motor windings. If you set B1 and B2 low, it will essentially short the winding, which may be used as a brake. Here is an article on using the L298N with an Arduino: http://www.instructables....-with-L298N-Dual-Moto/ Motor A truth tableENAIN1IN2Description0N/AN/AMotor A is off100Motor A is stopped (brakes)101Motor A is on and turning backwards110Motor A is on and turning forwards111Motor A is stopped (brakes) Motor B truth tableENBIN3IN4Description0N/AN/AMotor B is off100Motor B is stopped (brakes)101Motor B is on and turning backwards110Motor B is on and turning forwards111Motor B is stopped (brakes) That is from https://www.bananarobotic...-H-Bridge-Motor-Driver |
