1|1题目

使用一个LoRa模块完成LoRa模块上的屏幕输出控制并实现功能，使用提供的未完成工程进行开发。

任务要求：

Ø 通电后LED1、LED2灭，液晶屏显示如下信息：

---

主菜单  
K2.Formula 
K3.WIFI 
K4.QRCode  

---

Ø 当按下KEY2时，LED1亮,LED2灭并显示LXD数学公式,参数X为电流值，***表示公式：

Formula F：*************

Ø 当按下KEY3时，LED1灭，LED2亮并显示如下：

WIFI

​

Ø 当按下KEY4时，LED1亮，LED2亮并显示如下。

QRCode

​

Ø 能重复实现以上2~4的操作。

Ø 需调用封装的API实现。
