28335 ADC采样结果经DMA模块传输到MCBSP发送缓冲寄存器中再发送出去,问时钟配置要求

Other Parts Discussed in Thread: CONTROLSUITE

 请问adc的采样速率是否要比mcbsp发送速率低一些?还是说需要什么特殊的配置要求。
  • 您可以结合示例程序来看一下

    可以下载controlSuite并找到:

    C:\ ti \ controlSUITE \ device_support \ f2833x \ v142 \ DSP2833x_examples_ccsv5 \ adc_dma

    以及

    C:\ti\controlSUITE\device_support\f2833x\v142\DSP2833x_examples_ccsv5 \ mcbsp_loopback_dma 了解如何使用DMA配置McBSP

    请注意

    The CPU and the DMA controller communicate with the McBSP through 16-bit-wide registers accessible via the internal peripheral bus. 只能通过16bit通信
