struct MAC_Message * | SPI_PeekFullBuf () |
Get a MAC_Message buffer containing a received SPI Message. More... | |
void | SPI_DequeueFullBuf () |
Remove a processed Full Buffer from the SPI Queue. More... | |
ca_error | SPI_Exchange (const struct MAC_Message *pTxBuffer, struct ca821x_dev *pDeviceRef) |
Exchange Messages across SPI. More... | |
ca_error | SPI_Send (const uint8_t *buf, u8_t *response, struct ca821x_dev *pDeviceRef) |
Send Request over SPI. More... | |
void | SPI_ExchangeComplete () |
Function to be called from the BSP when an exchange operation has been completed. More... | |
void | SPI_Initialise (void) |
Initialise SPI buffers and call BSP SPI init. More... | |
bool | SPI_GetExternallyInUseStatus (void) |
Checks if the SPI is being used by something other than the RF chip. More... | |
Variables | |
struct MAC_Message | SPI_Receive_Buffer [SPI_RX_FIFO_SIZE] |
Cyclic SPI receive message FIFO. More... | |
SPI Communication Driver Functions.
struct MAC_Message SPI_Receive_Buffer[SPI_RX_FIFO_SIZE] |
Cyclic SPI receive message FIFO.
Messages are read from the SPI and put into the next available index.
