Hello every:

 

I use TWR-K70,   ADC trigger dma, CW10.6.

1)  When ADC_SC1 -> coco set 1, I use software start DMA,    it can work well;

2) When i use ADC automatic trigger DMA, it can start DMA.

   And I config :

          Master_Adc_Config.STATUS2  =

                                                     | DMAEN_ENABLED     // enable DMA

 

         DMAMUX_CHCFG_SOURCE(DmaMux_Sou)              // assign DMA trigger source     ,the DmaMux_Sou  is  41

    

      delete the software trigger  DMA ;

other configration is the same as   " 1) "

 

 

What's wrong whith me ?

 

Thank you !

Linda
