    FX3's I2C register- vs. DMA-transfer-mode

    robert.kliemann

      Hi,

         

      what's exactly the difference (on hardware-level) between the register- and the DMA-transfer mode of the I2C-interface in FX3?

         

      I understood, the register-mode should be used if only some bytes are to be transferred and the DMA-mode in case of more data (which should be multpile of 16 bytes).

         

      Is the behaviour on the I2C-wire the same using either register- or DMA-mode or are there some differences? Are there any differences in transfer-speed?

         

       

         

      Regards!
