Data Fields
unsigned int	baseAddr
unsigned int	intNum
unsigned int	intPriority
uint32_t	rxChannelIndex
uint32_t	txChannelIndex

Detailed Description

UARTTivaDMA Hardware attributes.

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

• inc/hw_memmap.h
• inc/hw_ints.h

A sample structure is shown below:

const UARTTivaDMA_HWAttrs uartTivaHWAttrs[] = {
    {
        .baseAddr = UART1_BASE,
        .intNum = INT_UART1,
        .intPriority = (~0),
        .rxChannelIndex = UDMA_CH22_UART1RX,
        .txChannelIndex = UDMA_CH23_UART1TX,
    },
    {
        .baseAddr = UART3_BASE,
        .intNum = INT_UART3
        .intPriority = (~0),
        .rxChannelIndex = UDMA_CH16_UART3RX,
        .txChannelIndex = UDMA_CH17_UART3TX,
    },
};
