Hi all
at the moment i'm trying to create a lighting sequencer , known as a lightingdesk that has DMX output.
everything seems to work ok to the eye when i look at my leds but the serial monitor show a sort of blok-ing moment when it gets the data from the SDcard.
before i used the normal SD library and it took around the 35400 micros to het the data.
now with the SDfat library it takes 24700 micros, so a BIG improvement.
but still, i use the arduino DUE which has DMA.
and SDfat should use the DMA feature from the DUE but its not nearly 10x faster i see on other forums.
so maby someone can make it more clear to me and maby have some improvements to the sketch.
many thanks to all.
