MSP432P401R: Timer32 - Delay function

Hi,

I'm working with a Timer32 to create a simple delay API to use for my future projects.

It seems to work with 1s duration (I don't have an oscilloscope at hand to check for smaller values..).

I would like some advices about the code (Is it enough to work with any ms/µs duration values?), and if a better & easier way to do a delay exists (Maybe with the Timer32 interrupt, or even without a Timer32?).

Remark: the minimum delay duration needed for my future projects is 10µs.

#include "driverlib.h"

void delay_init(void)
{
    Timer32_initModule(TIMER32_0_BASE, TIMER32_PRESCALER_1, TIMER32_32BIT, TIMER32_PERIODIC_MODE);

    Timer32_disableInterrupt(TIMER32_0_BASE);
}

void delay(uint32_t duration_us)
{
    Timer32_haltTimer (TIMER32_0_BASE);
    Timer32_setCount  (TIMER32_0_BASE, 24 * duration_us);
    Timer32_startTimer(TIMER32_0_BASE, true);

    while (Timer32_getValue(TIMER32_0_BASE) > 0);
}

int main(void) 
{
    WDT_A_holdTimer();

    CS_setDCOCenteredFrequency(CS_DCO_FREQUENCY_24);                   // 24000000 Hz
    CS_initClockSignal(CS_MCLK, CS_DCOCLK_SELECT, CS_CLOCK_DIVIDER_1); // 24000000 Hz

    GPIO_setAsOutputPin   (GPIO_PORT_P2, GPIO_PIN0);
    GPIO_setOutputLowOnPin(GPIO_PORT_P2, GPIO_PIN0);

    delay_init();

    while(1)
    {
        delay(1 * 1000 * 1000); // 1s

        GPIO_toggleOutputOnPin(GPIO_PORT_P2, GPIO_PIN0);
    }
}

Thanks,

Michaël
