Infineon SPI DMA 1 - Page 7

Implementation
QSPI Slave initialization (Cont.)
› The function IfxQspi_SpiSlave_initModule() is used to initialize the QSPI slave module
› Finally, the buffers used by the QSPI slave are initialized
The functions needed to initialize the QSPI Slave can be found in the iLLD header
IfxQspi_SpiSlave.h.
QSPI Master initialization
› The initialization of the QSPI master module is done by defining an instance of the
IfxQspi_SpiMaster_Config structure
› The structure is filled with default values by the function
IfxQspi_SpiMaster_initModuleConfig()
› Afterwards, the following parameters are modified to enable the DMA usage, set its
channels, interrupt priorities and IO port pins:
– DMA configuration: dma.useDma, dma.txDmaChannelId, dma.rxDmaChannelId
– Interrupts configuration: base.txPriority, base.rxPriority, base.erPriority,
base.isrProvider
– Pins configuration: pins
