Detailed Description

SPIMSP432DMA Hardware attributes These fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For MSP430Ware these definitions are found in:

• dma.h
• spi.h

A sample structure is shown below:

const SPIMSP432DMA_HWAttrs spiMSP432DMAHWAttrs[] = {
    {
        .baseAddr = EUSCI_B0_BASE,
        .clockSource = EUSCI_B_SPI_CLOCKSOURCE_SMCLK,
        .bitOrder = EUSCI_B_SPI_MSB_FIRST,

        .defaultTxBufValue = 0,

        .dmaIntNum = INT_DMA_INT1,
        .intPriority = (~0),
        .rxDMAChannelIndex = DMA_CH1_EUSCIB0RX0,
        .txDMAChannelIndex = DMA_CH0_EUSCIB0TX0
    },
    {
        .baseAddr = EUSCI_B2_BASE,
        .clockSource = EUSCI_B_SPI_CLOCKSOURCE_SMCLK,
        .bitOrder = EUSCI_B_SPI_MSB_FIRST,

        .defaultTxBufValue = 0,

        .dmaIntNum = INT_DMA_INT2,
        .intPriority = (~0),
        .rxDMAChannelIndex = DMA_CH5_EUSCIB2RX0,
        .txDMAChannelIndex = DMA_CH4_EUSCIB2TX0
    }
};
