Call printfDMA: This put data in the circular buffer and then calls xTaskNotifyGive (printTaskHandle) to release the block. The print task should then print out the characters. WebIf you need more efficiency, you might want to use the non-blocking _IT or _DMA HAL functions and implement the interrupt&completion callbacks such that they e.g. return data in a FreeRTOS queue.
