新手求问，在C:\ti\tirtos_cc32xx_2_16_01_14\products\tidrivers_cc32xx_2_16_01_13\packages\ti\drivers找到相关的API，但是不知如何使用，请问有没有相关资料可供参考？

多谢~

    Alvin Chen,

      你好，我之前浏览过那个例程，那个例程好像是non-os下实现的，请问一下rtos下使用和non-os下使用的是同一套api吗？

    SPI_Handle      handle;
SPI_Params      params;
SPI_Transaction spiTransaction;

SPI_Params_init(&params);
params.bitRate  = someNewBitRate;
handle = SPI_open(someSPI_configIndexValue, &params);
if (!handle) {
    System_printf("SPI did not open");
}
Transferring data
Data transmitted and received by the SPI peripheral is performed using SPI_transfer(). SPI_transfer() accepts a pointer to a SPI_Transaction structure that dictates what quantity of data is sent and received.
SPI_Transaction spiTransaction;

spiTransaction.count = someIntegerValue;
spiTransaction.txBuf = transmitBufferPointer;
spiTransaction.rxBuf = receiveBufferPointer;

ret = SPI_transfer(handle, &spiTransaction);
if (!ret) {
    System_printf("Unsuccessful SPI transfer");

    请看目录下的：C:\ti\tirtos_cc32xx_2_16_01_14\products\tidrivers_cc32xx_2_16_01_13\docs\tidriversAPIs.html

    接口函数如下;
