Configure DMA Channel
DMADest = &DMABuf1[0];
DMASource = &DMABuf2[0];
DMACH1AddrConfig(DMADest,DMASource);
DMACH1BurstConfig(31,2,2); //Will set up to use 32-bit datasize, pointers are based on 16-bit words
DMACH1TransferConfig(31,2,2); //so need to increment by 2 to grab the correct location
DMACH1WrapConfig(0xFFFF,0,0xFFFF,0);
书上说31指的是多少个字，，但是这里却说多少各位，，，有没有人知道啊？郁闷死了
