Spi data communication via dma, aurix tc2xx microcontroller training

Implementation

Interrupt Service Routines (ISR):

›

The following ISRs are implemented to ensure a proper SPI communication in

DMA mode:

–

SPI Master error interrupt ISR_qspi2_Er() ISR calls the function:

–

IfxQspi_SpiMaster_isrError()

–

SPI Slave error interrupt ISR_qspi3_Er() ISR calls the function:

–

IfxQspi_SpiSlave_isrError()

–

SPI Master transmit interrupt ISR_dma_ch1() ISR calls the function:

–

IfxQspi_SpiMaster_isrDmaTransmit()

–

SPI Master receive interrupt ISR_dma_ch2() ISR calls the function:

–

IfxQspi_SpiMaster_isrDmaReceive()

–

SPI Slave transmit interrupt ISR_dma_ch3() ISR calls the function:

–

IfxQspi_SpiSlave_isrDmaTransmit()

–

SPI Slave receive interrupt ISR_dma_ch4() ISR calls the function:

–

IfxQspi_SpiSlave_isrDmaReceive()

The functions listed above can be found in the iLLD headers IfxQspi_SpiMaster.h

and IfxQspi_SpiSlave.h
