Table 40. SPI_GetBuffer
Note: The above function is only for SPI Interrupt driven mode.
Caution:
– Take care not to access the string until reception is complete.
– Any data received before calling this function is ignored
– The data reception will stop if any error occurs during reception.

SPI_GetBuffer
Void SPI_GetBuffer (unsigned char *PtrToBuffer, un-
signed char NbOfBytes)
Starts reception of data in the interrupt service routine and
stores it in user defined area for SPI Interrupt driven
mode.
*PtrToBuffer
Start address of the user buffer.
NbOfBytes
Number of bytes to be received.
None
1. The SPI should be configured correctly.
2. You must define the SPI Interrupt driven reception
mode 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.
None
You must call SPI_IsReceptionCompleted after this to
check the reception status.
