Field Documentation

§ transferMode

SPI_TransferMode SPICC26XXDMA_Object::transferMode

Blocking or Callback mode

§ transferTimeout

unsigned int SPICC26XXDMA_Object::transferTimeout

Timeout for the transfer when in blocking mode

§ transferCallbackFxn

SPI_CallbackFxn SPICC26XXDMA_Object::transferCallbackFxn

Callback function pointer

§ mode

SPI_Mode SPICC26XXDMA_Object::mode
