Switch external interface tx communication to DMA:
In the previous version the transmitting of data was done in polling mode. With the introduction of new sensors the length of commands send to the sensor may increase and have a impact to the runtim behavior of the SW. To avoid this the DMA transfers for TX has been activated.
