Table 32. SPI_PutBuffer
Notes:
– The above function is only for SPI Polling mode.
– For transmission in software slave mode, you must define SPI_SLAVE_CONFIG in
Caution: The application can lose control if the SPI is disabled while using this function in poll-

ing mode.
SPI_PutBuffer
SPI_TxErrCode_t SPI_PutBuffer (const unsigned char
*PtrToBuffer, unsigned char NbOfBytes)
Transmits data bytes from the user defined area for SPI
Polling mode. The data transmission will stop if any error
occurs during transmission. The transmission status will
be returned.
*PtrToBuffer
Start address of the user buffer.
NbOfBytes
Number of data bytes to be transmitted.
SPI_TX_WCOL
If write collision error occurs.
SPI_TX_MODF
If master mode fault occurs.
SPI_TRANSMIT_OK
If there is no error in transmission.
1. SPI should be configured correctly.
2. You must define SPI Polling transmission mode in
ST7lib_config.h.
None
