频率发生器开发需要做哪些组件？

你好，古贝
欢迎来到PSoC的迷人世界！
你可以用不同的方式来产生信号。
让我问你一些问题：
1）你想产生什么样的波形？正弦/正方形/三角形/斜面…？
2）信号的频率是多少？
理想情况下，当你想要正弦等波形时，你可以使用预定义的查找表，并用这些值更新电压数模转换器（VDAC）。从表到VDAC的值的传递可以使用直接存储器存取（DMA）来完成。
更新速率决定波形的频率。LUT中的值将决定波形的形状，并且LUT中的值的范围将决定波形的振幅。

  Hi gube,
     
    Welcome to the fascinating world of PSoC!
    There are different ways in which you can generate signals.
    Let me ask you some questions:
    1) What kind of waveforms do you intend to generate? Sinusoidal / Square / Triangular / Ramp..?
    2) What is the frequency of the signal?
     
    Ideally, when you want waveforms such as sine, you can use a predefined Look Up table and update the Voltage Digital to Analog Converter (VDAC) with these values. The transfer of values from the table to VDAC can be done using a Direct Memory Access (DMA).
    The rate of update determines the frequency of the waveform. The values in the LUT will determine the shape of the waveform and the range of the values in the LUT will determine the amplitude of the waveform.

有一个名为WaveDAC8的组件，您必须搜索并添加它，如文档所示。这个组件有能力生成任何你喜欢的波形输出。

  There is a component named WAVEDAC8 which you have to search for and add it like the documentation shows. This component has the ability to generate any wave-output you like.

这是一站式的解决方案！
您可以在这里找到关于WaveDAC8组件的应用注意事项
DMA的基础知识将帮助你前进。在DMA上的应用说明示出了使用查找表生成正弦波的例子。这可以在这里找到
下面的快照显示了这个项目的示意图。

  That's a one stop solution!
    You can find the application note on WaveDAC8 Component here
    The basics about DMA will help you get going. The application note on DMA shows an example of sine wave generation using Look up table. This can be found here

对不起，前一个帖子没有附加快照。因此，附加文件。

谢谢大家。我在搜索下载方面没有取得成功。我发现和阅读文档提供，但不知道如何把组件。这是不可能的，但就像一个好的bug，这是躲避我！



     以下为原文
  Thanks guys.  I haven't been successful in my searches for a download.  I have found and read the documentation that is provided but can't figure out how to get the component.  It can't be that difficult but just like a good bug, it's eluding me!  

很容易！你有正确的URL从最后一个职位。下载PDF，下载zip并提取到一个新目录。
现在看看PDF的第11页，它一步一步地展示如何为您的项目安装WaveDAC8组件。
快乐阅读！
鲍勃



     以下为原文
  Its easy! you have the right URL from the last post. Download the PDF, download the zip and extract to a new directory.
    Now look at page 11 of the PDF, it shows step-by-step how to install the WAVEDAC8 component for your project.
     
    Happy reading!

对不起，我没有回答最初的问题…我想生产DTMF频率对。我相信这意味着我需要产生正弦符号波。



     以下为原文
  Sorry, I failed to answer the initial question...
I want to produce DTMF frequency pairs. I believe that means I need to produce sinusoidal sign waves.

谢谢鲍伯。男孩，我感到羞怯！我在阅读过程中还远远不够。我可以把它归咎于太多的颠簸或太多的马拉松编程会话，但事实是我搞砸了。再次感谢



     以下为原文
  Thanks Bob. Boy do I feel sheepish! I just didn't go far enough in my readings. I could blame it on too much Jolt or too many marathon programming sessions but the fact is I just goofed. Thanks again
