Detailed Description

UARTMSP432 Hardware attributes.

These fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For MSP432Ware these definitions are found in:

• uart.h

A sample structure is shown below:

unsigned char uartMSP432RingBuffer[2][32];

const UARTMSP432_HWAttrs uartMSP432HWAttrs[MSP_EXP432P401RLP_UARTCOUNT] = {
    {
        .baseAddr = EUSCI_A0_BASE,
        .intNum = INT_EUSCIA0,
        .intPriority = (~0),
        .clockSource = EUSCI_A_UART_CLOCKSOURCE_SMCLK,
        .bitOrder = EUSCI_A_UART_LSB_FIRST,
        .numBaudrateEntries = sizeof(uartMSP432Baudrates) /
                              sizeof(UARTMSP432_BaudrateConfig),
        .baudrateLUT = uartMSP432Baudrates,
        .ringBufPtr  = uartMSP432RingBuffer[0],
        .ringBufSize = sizeof(uartMSP432RingBuffer[0])
    },
    {
        .baseAddr = EUSCI_A2_BASE,
        .intNum = INT_EUSCIA2,
        .intPriority = (~0),
        .clockSource = EUSCI_A_UART_CLOCKSOURCE_SMCLK,
        .bitOrder = EUSCI_A_UART_LSB_FIRST,
        .numBaudrateEntries = sizeof(uartMSP432Baudrates) /
                              sizeof(UARTMSP432_BaudrateConfig),
        .baudrateLUT = uartMSP432Baudrates
        .ringBufPtr  = uartMSP432RingBuffer[1],
        .ringBufSize = sizeof(uartMSP432RingBuffer[1])
    }
};
