Detailed Description

SPI Parameters.

SPI Parameters are used to with the SPI_open() call. Default values for these parameters are set using SPI_Params_init().

Field Documentation

transferMode

SPI_TransferMode SPI_Params::transferMode

Blocking or Callback mode

transferTimeout

uint32_t SPI_Params::transferTimeout

Transfer timeout in system ticks

transferCallbackFxn

SPI_CallbackFxn SPI_Params::transferCallbackFxn

Callback function pointer

mode

SPI_Mode SPI_Params::mode

Master or Slave mode

bitRate

uint32_t SPI_Params::bitRate

SPI bit rate in Hz.

Maximum bit rates supported by hardware:

Device Family	Slave Max (MHz)	Master Max (MHz)
MSP432P4	16 MHz	24 MHz
MSP432E4	10 MHz	60 MHz
CC13XX/CC26XX	4 MHz	12 MHz
CC32XX	20 MHz	20 MHz

Please note that depending on the specific use case, the driver may not support the hardware's maximum bit rate.

dataSize

uint32_t SPI_Params::dataSize

SPI data frame size in bits

frameFormat

SPI_FrameFormat SPI_Params::frameFormat

SPI frame format

custom

void* SPI_Params::custom

Custom argument used by driver implementation
