如何写一个状态指示灯？

#define LED_TIME_CYCLE 1500 // ms#define LED_TIME_OUTPUT 150 // ms
typedef enum { LED_ON, LED_OFF, }led_level_def;
typedef struct { uint16_t last_time_show_cycle; // 状态查询时间 uint16_t set_time_cycle; // 循环时间 uint16_t set_last_time; // 上一次电平输出时间 uint8_t curr_number; // 当前 uint8_t next_number; // 下一个指示次数 void (*led_set)(led_level_def); }led_para_def;
// LED 设置void led_set_level(led_level_def level){ if(level == LED_ON){ GPIO_ResetBits(GPIOB, GPIO_Pin_13); } else{ GPIO_SetBits(GPIOB, GPIO_Pin_13);  }}
// 参数初始化led_para_def led_para = { .set_time_cycle = (uint16_t)-1, .curr_number = 0, .led_set = led_set_level,};
// 调用频率小于 10 msvoid led_set_handle(led_para_def *p_led_para, uint32_t time){ // 设置 LED if(((uint16_t)(time - p_led_para->set_last_time)) >= p_led_para->set_time_cycle) { p_led_para->set_last_time = time; if(p_led_para->curr_number) { p_led_para->led_set(((p_led_para->curr_number & 1) == 1) ? LED_OFF : LED_ON); p_led_para->curr_number--; if(p_led_para->curr_number == 0) { p_led_para->set_time_cycle = (uint16_t)-1;// 下一个周期不再进入 } } } // 更新当前参数（1.5 s 更新一次） if(((uint16_t)(time - p_led_para->last_time_show_cycle)) >= LED_TIME_CYCLE){ p_led_para->last_time_show_cycle = time;
 if(!p_led_para->curr_number){ uint8_t number = p_led_para->next_number; // 获取当前指示次数 // 限制闪烁次数 if(number < LED_TIME_CYCLE / LED_TIME_OUTPUT / 2){ p_led_para->curr_number = number * 2 - 1; p_led_para->set_last_time = time; p_led_para->set_time_cycle = LED_TIME_OUTPUT; p_led_para->led_set(LED_ON); } } }}
// number 闪烁次数void led_show(led_para_def *p_led_para, uint8_t number){ p_led_para->next_number = number;}
