【得捷电子Follow me第2期】任务4：日历&时钟 [复制链接]

 

分任务1：日历&时钟——完成一个可通过互联网更新的万年历时钟，并显示当地的天气信息

建议搭配器件：Adafruit ESP32-S3 TFT Feather

 

官网有个很好的参考示例

https://learn.adafruit.com/mini-weather-station-esp32-s2-tft

免费的天气服务

https://www.sojson.com/api/weather.html

 

利用http get请求库函数，得到json格式的天气数据，解析后在屏幕显示即可

import time
import board
import ssl
import wifi
import socketpool
import adafruit_requests
from adafruit_display_text import label, wrap_text_to_lines
from adafruit_bitmap_font import bitmap_font

color = 0xF01414
font = bitmap_font.load_font("wenquanyi_13px.pcf")

display = board.DISPLAY
display.brightness = 0.25 
display.rotation = 0 

JSON_TIME_URL = "http://quan.suning.com/getSysTime.do"

pool = socketpool.SocketPool(wifi.radio)
requests = adafruit_requests.Session(pool, ssl.create_default_context())

def refresh_screen(print_text):
    text_area = label.Label(font, text=print_text, scale=1)
    text_area.x = 2
    text_area.y = 10
    text_area.scale = 1
    text_area.color = color
    display.show(text_area)

def get_data():
    try:
        response = requests.get(JSON_TIME_URL)
    except ConnectionError as e:
        print("Connection Error:", e)
        print("Retrying in 60 seconds")
    time_data = response.json()['sysTime2'][:-3]

    try:
        city_code = "101200101"
        url = JSON_weather_URL.format(city_code)
        response = requests.get(url)
    except ConnectionError as e:
        print("connect error:{},retry in 60s".format(e))
    weather_data = response.json()
    cityInfo = weather_data['cityInfo']
    city_weather = weather_data['data']
    forecast = city_weather['forecast']
    dis_str = ""+cityInfo['parent']+' '+cityInfo['city']
    dis_str += "  "+time_data
    dis_str += "\n" + forecast[0]['week']
    dis_str += ' 空气质量：' + city_weather['quality']
    dis_str += "\n温度："+city_weather['wendu']+"℃"
    dis_str += "  湿度：" + city_weather['shidu']
    dis_str += "\n明天最"+forecast[1]['high']+' 最'+forecast[1]['low']
    return dis_str

while not wifi.radio.ipv4_address:
    try:
        wifi.radio.connect(os.getenv('CIRCUITPY_WIFI_SSID'), os.getenv('CIRCUITPY_WIFI_PASSWORD'))
    except ConnectionError as e:
        print("connecti error:{},retry in 2s".format(e))
    time.sleep(2)
    
print("get ip:", wifi.radio.ipv4_address)

while True:
    info = get_data()
    refresh_screen(info)
    time.sleep(60)
    

效果：
