各位大侠，
我用cc3200 spi 做master使用dma输出时，发现时钟间有间隔，比如我设置dma为8bit ,发现每8个时钟脉冲之间有间隔，而不是连续的，请问这个正常吗，如何消除这个间隔。谢谢
您可以看一下 
给出的说明
The SPI driver operates on some key definitions and assumptions:
The driver operates transparent from the chip select. Some SPI controllers feature a hardware chip select to assert SPI slave peripherals. See the specific peripheral implementations on chip select requirements.
The SPI protocol does not account for a built-in handshaking mechanism and neither does this SPI driver. Therefore, when operating in SPI_SLAVE mode, the application must provide such a mechanism to ensure that the SPI slave is ready for the SPI master. The SPI slave must call SPI_transfer() before the SPI master starts transmitting. Some example application mechanisms could include:
Timed delays on the SPI master to guarantee the SPI slave is be ready for a SPI transaction.
A form of GPIO flow control from the slave to the SPI master to notify the master when ready.
