GD32F303按键控制灯的亮灭

#include "main.h"
#include "bsp.h"
#include "systick.h"
#include "gd32f303c_eval.h"
 int main (void)
 {
     systick_config();
     gd_eval_led_init(LED2);
     gd_eval_key_init(KEY_WAKEUP,KEY_MODE_GPIO);
     
     while(1)
 {
     if (RESET == gd_eval_key_state_get(KEY_WAKEUP))
         {
          delay_1ms (10);
             {
                 if (RESET == gd_eval_key_state_get(KEY_WAKEUP)){
                 gd_eval_led_toggle(LED2);
             }
             while(RESET == gd_eval_key_state_get(KEY_WAKEUP));
}
            } 
    }
}

先要判断按键按下，然后延时消抖，确认按键按下，灯的状态取反，最后再确认按键松手
