Data Fields
unsigned int	baseAddr
unsigned int	intNum
unsigned int	intPriority
uint32_t	flowControl
unsigned char *	ringBufPtr
size_t	ringBufSize

Detailed Description

UARTTiva 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
• driverlib/uart.h

A sample structure is shown below:

unsigned char uartTivaRingBuffer[2][32];

const UARTTiva_HWAttrs uartTivaHWAttrs[] = {
    {
        .baseAddr = UART0_BASE,
        .intNum = INT_UART0,
        .intPriority = (~0),
        .flowControl = UART_FLOWCONTROL_NONE,
        .ringBufPtr  = uartTivaRingBuffer[0],
        .ringBufSize = sizeof(uartTivaRingBuffer[0])
    },
    {
        .baseAddr = UART1_BASE,
        .intNum = INT_UART1,
        .intPriority = (~0),
        .flowControl = UART_FLOWCONTROL_NONE,
        .ringBufPtr  = uartTivaRingBuffer[1],
        .ringBufSize = sizeof(uartTivaRingBuffer[1])
    }
};
