7.8.1.2.2 Workflow

  1. Start the DMA transfer job with the allocated DMA resource and transfer descriptor. 
    dma_start_transfer_job(&example_resource);
  2. Set the software trigger for the DMA channel. This can be done before or after the DMA job is started. Note that all transfers needs a trigger to start. 
    dma_trigger_transfer(&example_resource);
  3. Waiting for the setting of the transfer done flag. 
    while (!transfer_is_done) {
    /* Wait for transfer done */
}
