I used dma for move the data which get from sensor from UART FIFO to SDARM. but by default, the dma controller use 1 double worlds to get one byte from FIFO. that really waste a lot of memory. so now the question comes, i want to use DMA but i can not waste 3 another byte in SDARM. is there any solution that the dma can use one byte for one byte in memory.
thanks a lot
