Table 34. SPI_PutBuffer
Notes:
– The above function is only for SPI Interrupt driven mode.
– For transmission in software slave mode, you must define SPI_SLAVE_CONFIG in
Caution:
– Do not access the string until transmission is completed.
– Data transmission will stop if any error occurs during transmission.

ST7lib_config.h.
SPI_PutBuffer
Void SPI_PutBuffer (const unsigned char *PtrToBuffer,
unsigned char NbOfBytes)
Starts transmission of data in the interrupt service routine,
from the user defined area for SPI Interrupt driven mode.
*PtrToBuffer
Start address of the user buffer.
NbOfBytes
Number of data bytes to be transmitted.
None
1. The SPI should be configured correctly.
2. You must define the transmission mode as SPI Inter-
rupt driven in ST7lib_config.h.
3. You must enable interrupts for this mode.
4. For SPI Interrupt driven mode, SPI_IT_Function must
have been called in the Interrupt service routine.
You can call ‘SPI_IsTransmitCompleted’ after this function
to get the transmission status.
