Detailed Description

UARTMSP432 Baudrate configuration.

This structure is used to specifiy the EUSCI controller's clock divider settings to achieve the desired baudrate given the a clock input frequency. Divider values can be determined by referring to the MSP432 baudrate calculator. https://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSP430BaudRateConverter/index.html

A sample structure is shown below:

const UARTMSP432_BaudrateConfig uartBaudrates[] = {
    // {baudrate, input clock, prescalar, UCBRFx, UCBRSx, oversampling}
    {
        .outputBaudrate = 115200,
        .inputClockFreq = 12000000,
        .prescalar = 6,
        .hwRegUCBRFx = 8,
        .hwRegUCBRSx = 32,
        .oversampling = 1
    },
    {115200, 6000000,   3,  4,   2, 1},
    {115200, 3000000,   1, 10,   0, 1},
    {9600,   12000000, 78,  2,   0, 1},
    {9600,   6000000,  39,  1,   0, 1},
    {9600,   3000000,  19,  8,  85, 1},
    {9600,   32768,     3,  0, 146, 0}
};
