esp8266 NONOS SDK 软件定时器os_timer

基于ESP8266_NONOS_SDK-2.2.0

`os_timer_t OS_Timer_1;//定义软件定时器变量 int a=1;  void ICACHE_FLASH_ATTR OS_Timer_1_cb(void)//软件定时器的回调函数 { 	a=!a; 	gpio16_output_set(a); 	os_printf("\r-------------- into cb----------------\r\n"); }  void ICACHE_FLASH_ATTR OS_Timer_1_Init(u32 timemsm,bool time_repetitive)//软件定时器的初始化 { 	os_timer_disarm(&OS_Timer_1);//关闭软件定时器 	os_timer_setfn(&OS_Timer_1,(os_timer_func_t *)OS_Timer_1_cb,NULL);//设置定时器，设置回调函数 	os_timer_arm(&OS_Timer_1,timemsm, time_repetitive);//使能定时器 }  //主函数里面调用如下，即可实现500ms亮led，500ms灭 OS_Timer_1_Init(500,1);//软件定时器的初始化`
