FreeRTOS 软件定时器

代码如下：

#include <stdio.h>
#include "sdkconfig.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_system.h"
#include "esp_spi_flash.h"

#include "freertos/timers.h"

void Timer1Callback( TimerHandle_t xTimer ){
    printf("OK you'v successfully start a  software timer interrupt event\n");
}

void app_main(void)
{
    TimerHandle_t xTimer1;
    printf("START!!!\n");
    xTimer1=xTimerCreate("Timer1",pdMS_TO_TICKS(1000),pdTRUE,(void *)0,Timer1Callback);//创建了一个定时器，名字为Timer1，1秒钟执行一次，并且会重装载，ID为0，回调函数为Timer1Callback
    //创建好了定时器，下面就要启动
    xTimerStart(xTimer1,0);//xTimerStart( TimerHandle_t xTimer, TickType_t xTicksToWait );我们无需进行等待，所以设置等待时间为0
}
