滴答定时器定时：（放在主函数即可）

volatile unsigned int delay_times = 0;

//搭配滴答定时器实现的精确ms延时
void delay_ms(unsigned int ms) 
{
    delay_times = ms;
    while( delay_times != 0 );
}      

//滴答定时器中断
void SysTick_Handler(void)
{
    if( delay_times != 0 )
    {
        delay_times--;
    }
}

滴答定时器SYSCFG配置：

 

普通定时器.c文件：

#include "ti/driverlib/m0p/dl_core.h"
#include "ti_msp_dl_config.h"

//CPUCLK_FREQ 32000000     32000000/1000 = 32000 ->1ms 
void delay_ms(uint32_t ms)
{
    while(ms--)
    {
