rupts during initialization.
You can select master/ slave in hardware/ software mode
by selecting one of the below parameters.
SPI_MSTR_SW
Selects Master in software mode
SPI_SLAVE_SW
Selects Slave in software mode
SPI_HW
Selects hardware mode. You have to manage the SS pin
accordingly for selecting Master/Slave.
None
1. SS pin must be GND for default slave mode.
2. In hardware mode, if slave has to transmit, the SS pin of
the slave has to be released and made HIGH before writing
in SPIDR and reput to GND to avoid write collision error.
3. Fcpu must be defined in ST7lib_config.h.
4. SPI port pin must be configured correctly in hardware.
SPI_Clear_Flags
If you want to enable the interrupt, the SPI_ENABLE_IT pa-
rameter has to be passed in the SPI_Init function. After the
SPI_Init function is called, you should use the macro Ena-
bleInterrupts macro to reset the Interrupt mask.
SPI_Output_Disable
SPI_Output_Disable
Void SPI_Output_Disable (void)
None
None
None
None
If you want to enable the SPI output again, you must call
SPI_Init and pass the ‘SPI_DEFAULT’ parameter.
SPI_Init
Disables the alternate function of the SPI output.
