**制作一个基于 RTT-MicroPython 制作自带BGM的新型肺炎晴雨表****硬件准备**基于 “All in one ”的思想，采用 “麻雀1号开发板”，板载 wifi 、 LCD 屏、小喇叭、麦克风、摄像头等众多功能于一体，是 DIY 的首选利器。在本次的 DIY 中主要基于 RTT-MicroPython来实现，需要参考前面的一篇文章来烧录固件和同步工程，参考链接：[https://club.rt-thread.org/ask/question/423393.html](https://club.rt-thread.org/ask/question/423393.html)关于示例代码的使用需要参考该链接的文章进行操作。**软件准备****接口调用说明**关于数据的更新主要使用全国新型肺炎疫情的实时数据接口：[https://lab.isaaclin.cn/nCoV/](https://lab.isaaclin.cn/nCoV/)![数据接口.png](/uploads/202002/08/181141ylgb1bvbgl5lh0v0.png)具体的接口使用可自行查看更详细的说明，这里只使用到查询广东省的数据。![查询广东省的数据接口.png](/uploads/202002/08/181141r1r1ofcftezgnebh.png)根据上述说明：通过浏览器访问 [https://lab.isaaclin.cn/nCoV/api/area?latest=1&province=%E5%B9%BF%E4%B8%9C%E7%9C%81](https://lab.isaaclin.cn/nCoV/api/area?latest=1&province=%E5%B9%BF%E4%B8%9C%E7%9C%81)可以获得关于广东省的数据，如下：![网页返回的数据结果.png](/uploads/202002/08/181141ak9y7m0zfk330dx3.png)确认数据接口没有问题后就可在"麻雀1号开发板"上动手了。注意：这里必须要严格按照参考链接中的文章操作，烧录对应的固件和同步项目工程。**示例代码**可以在同步的项目工程中添加一个 py 文件，如命名为"comeon_wuhan.py"，复制下面的示例代码，再运行该文件即可。import userfunc
import utime as time
import rtthread
import json
from machine import LCD     # Import the LCD class from machine
from player import player
try:
    import urequests as requests
except ImportError:
    import requests
def func():
    lcd = LCD()                             # Create a LCD object
    #lcd.fill(lcd.WHITE)
    url = 'https://lab.isaaclin.cn/nCoV/api/area?latest=1&province=%E5%B9%BF%E4%B8%9C%E7%9C%81'
    resp_body = requests.get(url)
    #print(resp_body.text)
    resjson = json.loads(resp_body.text)
    #print(resjson)
    res = str(resjson['results'][0]['provinceName']+':'+'confirmedCount:'+str(resjson['results'][0]['confirmedCount'])+' curedCount:'+str(resjson['results'][0]['curedCount'])+' deadCount:'+str(resjson['results'][0]['deadCount']))
    print(res)
    data = "广东省"
    data1 = "累计确诊:"+str(resjson['results'][0]['confirmedCount'])
    data2 = "治愈人数:"+str(resjson['results'][0]['curedCount'])
    data3 = "死亡人数:"+str(resjson['results'][0]['deadCount'])
    c_data_list = ["深圳","广州","珠海","佛山","东莞","中山","惠州","汕头","湛江","肇庆","江门","阳江","梅州","清远","揭阳","韶关","茂名","汕尾","潮州","河源"]
    for i in range(20):
        c_data = c_data_list*
        c_data1 = "累计确诊:"+str(resjson['results'][0]['cities']*['confirmedCount'])
        c_data2 = "治愈人数:"+str(resjson['results'][0]['cities']*['curedCount'])
        c_data3 = "死亡人数:"+str(resjson['results'][0]['cities']*['deadCount'])
        lcd.fill(lcd.BLACK)
        userfunc.show_chinese(40,20,'武汉加油,中国加油!',0xFFE0,0x0000)
        userfunc.show_chinese(20,50,data,0xFFFF,0x0000)
        userfunc.show_chinese(0,70,data1,0xF800,0x0000)
        userfunc.show_chinese(0,90,data2,0x07E0,0x0000)
        userfunc.show_chinese(0,110,data3,0X8430,0x0000)
        userfunc.show_chinese(20,130,c_data,0xFFFF,0x0000)
        userfunc.show_chinese(0,150,c_data1,0xF800,0x0000)
        userfunc.show_chinese(0,170,c_data2,0x07E0,0x0000)
        userfunc.show_chinese(0,190,c_data3,0X8430,0x0000)
        time.sleep(3)
    resp_body.close()

def main():
    print("Welcome to RT-Thread MicroPython!")
    for i in range(30):
        play = player()
        play.opensong("http://music.163.com/song/media/outer/url?id=1418684451.mp3") #播放武汉加油的歌曲
        play.play()
        func()
        time.sleep(10)

if __name__ == '__main__':
    #注意这里需要替换为自己的手机热点的名称和密码
    rtthread.wifi_join("w0","test","12345678")
    #使用适当的延时，等待 WIFI 连接成功
    time.sleep(5)
    main()效果演示:伴随着“武汉加油”的 bgm 响起，LCD 屏就会循环刷新数据，相信不少的小伙伴，在自我居家隔离的时候，一个人挺无聊的，听听音乐，看看实时数据一起为“武汉加油”，希望早点恢复往日的平静。![武汉加油.png](/uploads/202002/08/181141gfqpdzseyz7dzjh7.png)
