如何控制电机的方向

嗨，鲍伯，我用了你发给我的东西，把它用在我的代码里，但我仍然遗漏了什么东西。
所以你可以理解我在这个项目中所做的事情。我使用CY8C946624SXI来控制一个电机单元。我试图通过将电位器连接到输入端口0－7，以及端口0到5的输出速度来控制电机的速度。
通过SWITCH运行/停止连接到PORT0-1，并将CW/CW（方向）控制到PORT-0。
我试图能够改变速度，而马达正在运行，或在它不运行。并朝着正确的方向前进。
我附上了这个项目，你能看一下，看看我错过了什么。
谢谢

  Hi Bob, i used what you sent me and used it in my code but still i am missing something.
    so you can understand what i am trying to do in this project. I am using CY8C29466-24 SXI to control a motor unit. i am trying to control the speed of the motor by connecting the potentiometer to input PORT 0-7, and the output speed on PORT 0-5.
    Controlling it by swtiches RUN/STOP connected to PORT 0-1 , and CW/CCW ( direction ) to PORT 0-0.
    i am trying to be able to change speed while motor is running or while its not running. and by the right direction.
    I attached the project, can you take a look at it and see what am i missing in it.
     
    Thanks

嗨，鲍伯，
当我更改开关时，你发送给我的修改代码不起作用，一旦转到Run和CW或CW方向之一，它就会被卡住。我不确定我是否错过了什么。
谢谢



     以下为原文
  Hi Bob,
    the modified code that you sent me is not function when i change the switches, once it goes to RUN and one of the direction CW or CCW, it gets stuck. i am not sure if i am missing something.
    Thanks

您正在使用变量“IDATA”作为循环控件，并且在循环中给它分配一个值，因此循环永远不会正确终止。
另一方面，我怀疑你正把你的马达直接连接到PSoC的DAC输出，它会立即摧毁它。！
控制电机通常是用PWM来完成的，PWM具有不同的占空比的数字输出以控制速度。虽然PSoC能够驱动几毫安来驱动一个（非常）小的电机，但是由于运行的电机将产生（如发电机）的电压比允许的5V高，因此立即将保护电路立即吹入引脚，所以不能将电机直接连接到它。
在继续您的PSoC编程之前，试着做一个示意图并在这里张贴，我们将看看它。
鲍勃



     以下为原文
  You are using the variable "iData" as the loop-control and you are assignig a value to it within the loop, thus the loop will never terminate correctly.
    On the other hand I suspect that you are connecting your motor directly to the DAC output of the PSoC which will destroy it immediately!!
    Controlling a motor is usually done with a PWM which has a digital output with a varying duty-cycle to control the speed. Although the PSoC is able to drive a few mA to drive a (very) small motor you may NOT connect the motor directly to it because the running motor will create (like a dynamo) voltages that are grater than the allowed 5V and so blowing immediately the protection circuits at the pins.
    Before continuing with the programming of your PSoC try to make a schematic and post it here, we'll have a look at it.

在MyMeMOTROR函数中，它永远不会从循环中出来。



     以下为原文
  it never comes out from for loop in the MoveMotor function

我修理它，它与CW/CW一起工作，但是一旦我切换到停止，它停止马达，但不去我的其他功能。

  i fixed it, and it works with CW/CCW but once i switch to STOP, it stops the motor but doesnt go to my else function.

如果它是有用的，我将使用它，因为在完成之后，我必须捕获时间输入并将其与输出捕获PRT进行比较。
但是我怎么用呢？因为我必须使用DAC9（IDATA）手动使用电位器来改变输入。



     以下为原文
  if it will be helpful i will use it, because after i am done with that, i have to capture the time input and compare it to the output capture PRT.
    But how i use it ? because i have to vary the input manually using the potentiometer using DAC9 (iData)

尝试替换DAC9AWORKSTARTALL（X）；用DAC9X写盲（X）；
如果启用中断，并且等待时间很长，WrestESTALL可能会出现一些问题。



     以下为原文
   Try replacing DAC9_WriteStall(x); with  DAC9_WriteBlind(x);
    WriteStall might have some problems if interrupts are enabled and the latency is high.

这是更新的，停止条件仍然不正确。它应该是任何时候我切换到停止（！（电力和运行）应增加到钾肥价值。不恢复IDATA。

  thats the updated one, the STOP condition still not function right. it should be anytime i switch to stop (!(POWER&RUN)) should increase to the POT value. not resume the iData.

分钟，
正如最近有人说的：“我们可以告诉你如何捕鱼，但我们不会给你任何鱼。”
当程序停留在一个循环中时，尝试找出原因并相应地改变循环，我们这里没有硬件来测试所有的东西。正如我所看到的，你的编程技巧还没有完全开发出来，你需要更多的练习。我建议使用这个HTTP://Puxal.GbDist.C.UK/CyBooo/书来构造C的语法。
因为你和PSoC1一起工作，而你没有冰块（电路仿真器），所以很难找出出故障的原因。
PSoC3和PSoC5开发工具包配备了内置的调试功能（断点，监视变量等），以便使您的生活更容易，我建议：
给自己买一个冰块。昂贵，但它可以显示你的芯片上发生了什么。与一个CYC24466 DIP一起吊舱
或
买一个KIT-050（更便宜），并在那里开发/调试你的软件模块。这将额外教写硬件无关代码。当软件运行时，将源传递到目标PSoC。

  mins,
    as someone lately said:"We can show you how to catch fishi, but we will not give you any fish".
    When the program stays within a loop, try to find out why and alter the loop accordingly, we here do not have got the hardware you have got to test everything. As I could see, your programming skills are not yet fully developed, and you need a bit more practice. I would recommend  for syntax of C using this http://publications.gbdirect.co.uk/c_book/ book.
    Since you are working with PSoC1 and you do not have got an ICE-Cube (In-Circuit-Emulator) it is very difficult to find out the reason if something goes wrong.
    The PSoC3 and PSoC5 developement kits are equipped with a built-in debugging-feature (breakpoints, watching variables etc.) so to make your life easier i would suggest:
     
    Buy yourself an ICE-Cube. Expensive, but it can show what goes on in your chip. Comes together with a pod for a CyC29466DIP
    or
    Buy a Kit-050 (cheaper) and develop / debug your software-modules there. That will teach additionally to write hardware-independant code. When the software runs, transfer the source to your target-PSoC.

这是我第三次在同一个地方做一些修改，你没有接受我给你的所有建议，你没有纠正计时器时钟和周期…你必须更精确一些。
看看这个。作为提示：代码中出现的两倍以上的内容通常是可以优化的。
看看这两个新宏。

  It is now the third time i make some corrections at the very same places, you did not take the all the advices I gave you, you did not correct the timer clock and period..... you must be a bit more precise.
    Take a look at this. As a hint: everything that occurs more than twice in the code is often something that can be optimized.
    And have a look at the two new macros.
