cc2564 stm32f4 A3DPDemo_SRC

Other Parts Discussed in Thread: CC2564

Hi  TI

       在STM32f4平台上关于cc2564的A3DPDemo_SRC的例程中,在AUDIO.c文件中有个变量:AUDIO_Context.hfpAudio  一直没有想明白这个变量的用途,所以请教下TI的工程师,谢谢啦

  • HFP ——Hands Free Profile

    具体请看STM32F40_41xxx Bluetopia (FreeRTOS) Release Notes里的HPFdemo,路径:C:\ti\Connectivity\CC256X BT\CC256x STM32 Bluetopia SDK\v4.0.2.2

  • 恩恩,谢谢Viki Shi

    我还有一些疑问,在stm32f4的平台上。

       A3DPDemo_SRC 中的AUDIO.C变量AUDIO_Context.hfpAudio 赋值是在

      if(Frequency < 32000)
        {
         /* Output PLLI2S clock on MCO2 pin(PC9) */
         /* Enable the GPIOC peripheral          */
         RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOC, ENABLE);
         /* Configure MCO2 pin(PC9) in alternate function */
      GPIO_Init(GPIOC,  (GPIO_InitTypeDef *)&MCO2_GpioConfiguration);
            AUDIO_Context.hfpAudio = 1;
        }
        else
        {
            AUDIO_Context.hfpAudio = 0;
        }

    为什么AUDIO_Context.hfpAudio 赋值为1的条件是Frequency < 32000?这个变量的含义是? 这个变量在A3DPDemo_SRC的这个事例代码中有什么作用?

    非常感谢!
