2021山东省省赛高职组Lora点对点

题目

请选手选择两块 LoRa 模块实现无线通讯功能，并根据任务要求完成相关功能的开发，并发布程序到两块 LoRa 模块中，通上电源等待裁判评判。

本题提供了工程项目供选手使用。两个 LoRa 模块我们暂时命名为 LoRa(A) 和 LoRa(B)。
“竞赛参数信息”中提供了本题所需使用的频率信息。
设备上电，默认情况下两个 LoRa 模块上的 LED1 和 LED2 灯都是熄灭的。 LoRa(A)和 LoRa(B)两个模块液晶屏显示界面如下图所示

每按一次 Key2 键可以控制 LoRa(A)屏幕中小箭头以 LED1 开 → LED2 关 → LED2 开 → LED1 关 → LED1 开这样的顺序循环切换小箭头指示。每按一次 Key3 键可以控制 LoRa(A)屏幕中小箭头以 LED1 开 → LED1 关 → LED2 开 → LED2 关 → LED1 开这样的顺序循环切换小箭头指示。效果如下图所示

当 LoRa(A)中选中某个灯开或者关时，点击 Key4 键，可以控制 LoRa(B) 中对应 LED1 或者 LED2 的常亮或者熄灭。
LoRa(B)要根据自己模块中LED1灯或LED2灯的亮起或熄灭使用不同的图片或动画来表示。灯常亮使用“信号灯-0.bmp”、“信号灯-1.bmp”、 “信号灯-2.bmp”三张连续动画表示，灯熄灭使用“信号灯-0.bmp”来表示。效果如下图所示

分析

使用Lora模块进行点对点通讯
Lora 通讯频率为433000000附近的频率
库里面没有#include "sx1276.h"头文件，需要手动导入该头文件
