signal_light

1. 初始化 GPIO

2. 实现write_pin

   #define LED1_PIN GET_PIN(C, 13)
   
   static void write_pin(uint8_t value)
   {
   	rt_pin_write(LED1_PIN, value);
   }

3. 初始化模块

   slight_t *sl = slight_get_obj();
   slight_init(sl, write_pin, PIN_LOW);

4. 设置闪烁配置

   struct _sl_blink_cfg blink_cfg = {
       .active_time = 300,
       .period      = 5000,
       .times       = SL_BLINK_FOREVER,
   };
   slight_set_blink(sl, &blink_cfg);

5. 设置模式

   slight_set_mode(sl, eSL_MODE_BLINK);

6. 定时1ms轮询

   slight_poll();
