Color Unit试用项目准备工作——天气预报灯
屏幕上显示当天天气图标，当前温度。https://www.seniverse.com/“心知天气”提供的数据
{"results":[{"location":{"id":"WX38NPJ1DP88","name":"张家口","country":"CN","path":"张家口,张家口,河北,中国","timezone":"Asia/Shanghai","timezone_offset":"+08:00"},"now":{"text":"小雨","code":"13","temperature":"11"},"last_update":"2020-04-19T17:31:00+08:00"}]}
根据“心知天气”提供的数据也显示三天的天气情况。包含以下数据：
{"results":[{"location":{"id":"WX38NPJ1DP88","name":"张家口","country":"CN","path":"张家口,张家口,河北,中国","timezone":"Asia/Shanghai","timezone_offset":"+08:00"},"daily":[{"date":"2020-04-19","text_day":"小雨","code_day":"13","text_night":"多云","code_night":"4","high":"17","low":"2","rainfall":"3.1","precip":"","wind_direction":"西北","wind_direction_degree":"315","wind_speed":"45.00","wind_scale":"6","humidity":"64"},{"date":"2020-04-20","text_day":"晴","code_day":"0","text_night":"晴","code_night":"1","high":"8","low":"-2","rainfall":"0.0","precip":"","wind_direction":"西北","wind_direction_degree":"328","wind_speed":"45.00","wind_scale":"6","humidity":"21"},{"date":"2020-04-21","text_day":"晴","code_day":"0","text_night":"晴","code_night":"1","high":"7","low":"-3","rainfall":"0.0","precip":"","wind_direction":"西北","wind_direction_degree":"321","wind_speed":"45.00","wind_scale":"6","humidity":"32"}],"last_update":"2020-04-19T11:17:53+08:00"}]}
参考Mpython X 的python代码，设计 M5stack的Python代码：
因暂时没有实现，显示中文，所以“当前温度”用自制图片显示：
天气图标使用Firework软件进行处理，背景使用纯黑。
M5stack中设置背景为纯黑：setScreenColor(0x000000)
label1.setText(str( w1["results"]["now"]["temperature"]))
if w1["results"]["now"]["code"]== "0":
image0.changeImg("res/0.JPG")
if w1["results"]["now"]["code"]== "13":
image0.changeImg("res/13.JPG")
if w1["results"]["now"]["code"]== "4":
image0.changeImg("res/4.JPG")
只做了三张图片0.JPG为晴天；13.JPG为下雨；4.JPG为多云。
["results"]["now"]["code"]获取的是天气代码。对应如下表：
因“知心天气”限制一分钟访问20次。还因天气数据变化缓慢，所以中间使用time.sleep(20)延时访问。

完整代码。
由于今天一直阴天刮风，时不时的下雨，温度一降再降。
