Detailed Description

UARTMSP432E4 Hardware attributes.

The baseAddr, intNum, and flowControl fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For MSP432E4 driverlib these definitions are found in:

ti/devices/msp432e4/driverlib/inc/msp432e4xxx.h
ti/devices/msp432e4/driverlib/interrupt.h
ti/devices/msp432e4/driverlib/uart.h

intPriority is the UART peripheral's interrupt priority, as defined by the underlying OS. It is passed unmodified to the underlying OS's interrupt handler creation code, so you need to refer to the OS documentation for usage. For example, for SYS/BIOS applications, refer to the ti.sysbios.family.arm.m3.Hwi documentation for SYS/BIOS usage of interrupt priorities. If the driver uses the ti.dpl interface instead of making OS calls directly, then the HwiP port handles the interrupt priority in an OS specific way. In the case of the SYS/BIOS port, intPriority is passed unmodified to Hwi_create().

A sample structure is shown below:

unsigned char uartMSP432E4RingBuffer[2][32];
const UARTMSP432E4_HWAttrs uartMSP432E4HWAttrs[] = {
    {
        .baseAddr = UART0_BASE,
        .intNum = INT_UART0,
        .intPriority = (~0),
        .flowControl = UARTMSP432E4_FLOWCTRL_NONE,
        .ringBufPtr  = uartMSP432E4RingBuffer[0],
        .ringBufSize = sizeof(uartMSP432E4RingBuffer[0]),
        .rxPin = UARTMSP432E4_PA0_U0RX,
        .txPin = UARTMSP432E4_PA1_U0TX,
        .ctsPin = UARTMSP432E4_PIN_UNASSIGNED,
        .rtsPin = UARTMSP432E4_PIN_UNASSIGNED,
        .errorFxn = NULL
    },
    {
        .baseAddr = UART1_BASE,
        .intNum = INT_UART1,
        .intPriority = (~0),
        .flowControl = UARTMSP432E4_FLOWCTRL_NONE,,
        .ringBufPtr  = uartMSP432E4RingBuffer[1],
        .ringBufSize = sizeof(uartMSP432E4RingBuffer[1]),
        .rxPin = UARTMSP432E4_PB0_U1RX,
        .txPin = UARTMSP432E4_PB1_U1TX,
        .ctsPin = UARTMSP432E4_PIN_UNASSIGNED,
        .rtsPin = UARTMSP432E4_PIN_UNASSIGNED,
        .errorFxn = NULL
    }
};
