Continuous multiple ADC conversion and transfer by DMA implementation without any interrupts?

[ADIt]

Can we avoid the ADC and DMA transfer interrupts and check a status of DMA transfer done for new values converted by ADC with multiple channels?

My MCU is : STM32L1

Yes, you could inspect the DMA TC or HT flags.​

Hi is the Following code to do this OK?

Thanks

int adc_data_ready(void){

 int ret;

 ret = DmaHandle.DmaBaseAddress->ISR;

 if(ret&DMA_FLAG_TC1){

  __HAL_DMA_CLEAR_FLAG(DmaHandle,DMA_FLAG_TC1);  /* Clear TC Flag */

  ret = 1;

 }else{

  ret = 0;

 }

 return ret;

}

It might, check it and see.
