TMS320F280039C: 如何使用硬件SPI读写8位数据

Part Number: TMS320F280039C
Other Parts Discussed in Thread: C2000WARE

TMS320F280039C使用硬件SPI读写8位数据时,MISO一直得不到有效数据,不知道是不是读写函数调用错误导致还是什么问题,请问一下读写8位数据的函数是SPI_transitByte(base, txData)

SPI_receiveByte(base, dummyData)  吗,读字节函数的参数dummyData是什么参数啊Joy

上图是SPI波形,MISO总是回复0x01,有点难搞
