Hello. I am working with the DMA SPI SDK example for the QN9080. The spi dma transfer example uses a 32 bit buffer for the slave's transmit and receive buffers even though the data width is only 8 bits. I have the same code working in my project, but I would prefer to use 8 bit buffers to preserve memory. Is it possible to use 8 bit buffers for the DMA spi or are 32 bit buffers required?
