高职物联网屏幕控制亮灯模式

高职物联网模拟2

题目

通电后 LED1,LED2 亮，液晶屏显示如下信息：

                        |----------------|
			|    亮灯模式	 |
			|  1.常亮模式 <	 |
			|  2.呼吸模式	 |
			|  3.交替亮灭	 |
			|----------------|
1. 以上三项所对应的模式，1 为 LED1，LED2 常亮，2 为 LED1，LED2 呼吸灯模式，3 为 LED1，LED2 交替亮灭， LED1 亮则 LED2 灭，LED1 灭则LED2 亮，其间隔时间为 0.5 秒。
2. 对 < 符号进行上下的移动，当按下 KEY2 时向上移，当按下 KEY3 时向下移动。
3. 当 < 所处的选项，按下 KEY4 时，LED1，LED2 进入相应的模式。
4. 能重复以上步骤。

分析

• 屏幕显示文字会造成延迟效果，所以每次按键后显示文字和状态
• 延时的时候按键不能控制的解决方法 定义变量每次延时一秒
• 呼吸灯需要一直延时

/*头文件*/
#include "led_light.h"//呼吸灯头文件
/*所用函数*/
setBreathLedArg(64,128);//设置占空比 一般为64 128
switchLed1Breath();//设置LED1呼吸灯
switchLed2Breath();//设置LED2呼吸灯
breathLed();//开启呼吸灯
stopLedBreath();//停止呼吸
