物联网竞赛LoRa模块双击实现某些功能-新大陆

一、任务要求

1、第一次双击key3使得OLED屏幕显示工位号

2、第二次双击key3使得OLED屏幕显示某个图标

3、第三次双击key3使得OLED屏幕环境监测

4、能实现以上三步循环操作

二、代码main.c文件编写

#include <string.h>
#include "board.h"
#include "hal_key.h"
#include "tim-board.h"
#include "timer_handles.h"

#include "hal_oled.h"
#include "adc_reader.h"
#include "math.h"     //获取pow计算x的y次幂函数
#include "sht3x.h"    //温湿度
void Init() {
    BoardInitMcu();
    BoardInitPeriph();
    keys_init();//按键初始化
    setTimer2Callback(Time2Handler);
    Tim2McuInit(1);//定时器初始化，设置定时中断1ms中断一次
	OLED_Init();     //OLED初始化
	OLED_Clear();
	ADCS_Init();      //ADC初始化
}
void number()    //显示工位号
{
	OLED_ShowString(56,3,(uint8_t *)"01");
}

三、LoRa模块烧写代码

编译无错误，直接用STlink下载，"模组串口连接拨码开关"无要求

四、实验效果
