Really??? You're experiment was to load up the FIFO (8 bytes) using the DMA which would make me think that you would see bursts of fast data. --[][][][][][][][]---delay---[][][][][][][][]---delay---[][]etc... But, it sounds like there is still a delay between bytes --[]--[]--[]--[]--etc... That surprises me. -Chris
