怎么产生正弦，三角形和ECG信号

你好，利利瓦伦西亚，
在PSoC中可用的模拟外围设备如DAC（数字到模拟转换器）可以用来产生诸如三角形或正弦的波形。
为了生成三角波，可以将VDAC值增加到所需的最大振幅，然后线性减小到最小值。频率是由VDAC的更新速率确定的。
要生成正弦波，必须生成一个查找表，其值应该被馈送到VDAC。ADMAIs必须用于用查找表值更新VDAC。您可以参考这里的应用说明中说明的示例项目。
我不理解ECG信号的产生。你能详细说明一下你的要求吗？

  Hi Lilivalencia,
     
    The analog peripherals available in PSoC such as DAC (Digital to Analog Converter) can be used to generate waveforms such as triangular or sine.
     
    To generate triangular wave, you can increment the VDAC value till the maximum amplitude required, and then decrease to the minimum linearly. The frequency is determined by the update rate of the VDAC.
     
    To generate a sine wave, you have to generate a Look up table whose values should to be fed to the VDAC. A DMA has to be used to update the VDAC with the look up table values. You can refer to a sample project explained in the application note here.
    I didn't understand about the generation of ECG signal. Can you please elaborate about your requirement?

嗨，帕夫洛文，
你能简要介绍一下这个项目正在做什么吗？



     以下为原文
  Hi pavloven,
     
    Can you please brief about what is being done in the project?

我会回答任何问题，很快我就会写小评论。只是因为我的语言知识薄弱，它需要一些时间。



     以下为原文
   I shall answer any questions and soon I shall Write the small comment. Only it will demand some time owing to my weak knowledge of language.
