【Digi-Key Follow Me Issue 2】 Task 4: Sub-task 1: Calendar & Clock - Complete a perpetual calendar clock that can be updated via the Internet and display local weather information

0x0: Related APIs

This time, we use Amap to obtain regional information based on IP access.

Use Amap's API to get weather information based on region information

Use http://worldtimeapi.org/api/ip to get accurate time information

Create secrets.py

secrets = {
"ssid": "这是ssid",
"password": "这是密码",
"timezone": "Asia/Shanghai", # Checkhttp://worldtimeapi.org/timezones
"token":"高德api token"
}

0x1: Libraries used

Create a wifi link information file secrets.py

0x2: Writing code

import board
import wifi
import time
import ssl
import socketpool
import adafruit_requests
import displayio
import terminalio
import adafruit_imageload
from adafruit_display_text import label
import adafruit_bitmap_font.bitmap_font
import rtc
the_rtc = rtc.RTC()

After the basic library is imported, configure the WIFI connection

token = "高德API的token"
### connecte to a WiFi AP (AP name and password in secrets.py) ###
try:
    from secrets import secrets
except ImportError:
    print("WiFi secrets are kept in secrets.py, please add them there!")
    raise



print("Connecting to %s" % secrets["ssid"])
wifi.radio.connect(secrets["ssid"], secrets["password"])
print("Connected to %s!" % secrets["ssid"])

Get screen information and set screen direction

screen = board.DISPLAY

screen.rotation = 90

Set a background image

bitmap, palette = adafruit_imageload.load("/imgs/purple.bmp",bitmap=displayio.Bitmap,palette=displayio.Palette)

# Create a TileGrid to hold the bitmap

tile_grid = displayio.TileGrid(bitmap, pixel_shader=palette,tile_width=160, tile_height=240,# pixels number
                                         width=1, height=1) # tiles number

Create some display information

FONT = adafruit_bitmap_font.bitmap_font.load_font("mfyh-16.bdf")

arealabel = label.Label(FONT, x=0, y=32, text="北京市", scale=1, color=(255,255,255))

wtlabel = label.Label(FONT, x=0, y=62, text="晴", scale=1, color=(255,255,255))

wdlabel = label.Label(FONT, x=0, y=92, text="温度:", scale=1, color=(255,255,255))

sdlabel = label.Label(FONT, x=0, y=122, text="湿度:", scale=1, color=(255,255,255))

yearlabel = label.Label(FONT, x=0, y=152, text="时间:", scale=1, color=(255,255,255))

monthlabel = label.Label(FONT, x=0, y=182, text="", scale=1, color=(255,255,255))

daylabel = label.Label(FONT, x=0, y=212, text="", scale=1, color=(255,255,255))

# Create a Group to hold the TileGrid

group = displayio.Group()

# Add the TileGrid to the Group

group.append(tile_grid)

group.append(arealabel)

group.append(wtlabel)

group.append(wdlabel)

group.append(sdlabel)

group.append(yearlabel)

group.append(monthlabel)

group.append(daylabel)

screen.show(group)

tile_grid[0] = 0

time.sleep(1.0)

Print WIFI information and create SOKCET connection pool

print("IP addr:", wifi.radio.ipv4_address)

response = None

pool = socketpool.SocketPool(wifi.radio)

# 建立连接

session = adafruit_requests.Session(pool, ssl.create_default_context())

Use Gaode API to obtain the region code of the IP

while True:
    response = session.get("https://restapi.amap.com/v3/ip?key="+token)
    data = response.json()
    #print("data:",data["adcode"])
    adcode = data["adcode"]
    time.sleep(1)
    break

Use worldtimeapi to get local time

while True:
    response = session.get("http://worldtimeapi.org/api/ip")
    json = response.json()
    current_time = json["datetime"]
    the_date, the_time = current_time.split("T")
    year, month, mday = [int(x) for x in the_date.split("-")]
    the_time = the_time.split(".")[0]
    hours, minutes, seconds = [int(x) for x in the_time.split(":")]
    # We can also fill in these extra nice things
    year_day = json["day_of_year"]
    week_day = json["day_of_week"]
    # Daylight Saving Time (夏令时)?
    is_dst = json["dst"]
    now = time.struct_time(
        (year, month, mday, hours, minutes, seconds+1, week_day, year_day, is_dst) )
    the_rtc.datetime = now
    time.sleep(1)
    break
loopdata = 600

Use Amap API to refresh data information regularly

while True:
    #yearlabel.text = "时间:"+str(the_rtc.datetime.tm_year)
    monthlabel.text = ""+str(the_rtc.datetime.tm_mon)+"-"+str(the_rtc.datetime.tm_mday)+""
    daylabel.text = "" + str(the_rtc.datetime.tm_hour) + ":" + str(the_rtc.datetime.tm_min) + ":"+str(the_rtc.datetime.tm_sec)+""
    try:
        if loopdata==600:
            response = session.get("https://restapi.amap.com/v3/weather/weatherInfo?key="+token+"&city="+adcode)
            data = response.json()
            #print("data:",data["adcode"])
            wd = data["lives"][0]["temperature_float"]
            sd = data["lives"][0]["humidity_float"]

            wdlabel.text ="温度: "+ wd+"°"
            sdlabel.text = "湿度: "+sd+"%"
            arealabel.text =  data["lives"][0]["province"]
            wtlabel.text =  data["lives"][0]["weather"]
            loopdata=0
        else:
            loopdata = loopdata +1
        time.sleep(1)
    except:
        pass

The effect is as follows:

After studying the second phase of Digi-Key Follow Me, I learned more modern MCU development skills. Using Python can develop programs and implement projects more quickly.

Congratulations on completing the task, and you have also learned something new.
