SPI_GetByte
Unsigned char SPI_GetByte (void)
Returns the most recent Byte received in SPI Polling or SPI
Interrupt driven mode.
None
Unsigned char
Returns the received data byte.
1. The SPI should be configured correctly.
2. You must define SPI Polling or SPI Interrupt driven mode
in ST7lib_config.h.
3. You must enable interrupts for SPI Interrupt driven mode.
4. In both SPI Polling and SPI Interrupt driven modes you
must call SPI_IsReceptionCompleted before this function to
check the reception status.
5. For SPI Interrupt driven mode, SPI_IT_Function must
have been called in the Interrupt service routine.
None
None
