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
