CC2640R2F SPI发送数据没波形

Dear All

在CC2640R2F的simple_peripheral的工程添加了SPI的驱动，代码如下，可以调用测量一直没波形，抓打印已经是有跑到SPI写数据的函数了

在SimplePeripheral_init里面已经加了void SPI_Init(void)

在SimplePeripheral_taskFxn的开头按如下添加

uint8_t temp[1] = {0xff};
SimplePeripheral_init();
SPI_ReadWriteData(temp, NULL, sizeof(uint8_t));
// Application main loop

下面是SPI的驱动代码，请帮忙看看哪里有问题，谢谢

Kevin Qiu1：

有用C:\ti\simplelink_cc2640r2_sdk_4_20_00_04\examples\rtos\CC2640R2_LAUNCHXL\drivers\spimaster这里的例程试过吗
