Network clock for esp8266 [Copy link]

 

 

I haven't posted for a long time, waiting for the holiday. . I'm bored and wrote a post about the network clock. Welcome to correct me. 1. As usual, I'll post a picture of the final effect first 2. The accessories are as follows: esp8266 board, lcd5110, a data cable, a breadboard, a power bank, and some Dupont cables 3. Principle: Turn on the computer and connect to wifi, and get the current time through the API. Then pass an internal function to loop. In order to ensure the accuracy of the time, the time is automatically corrected every hour. 4. Code: def connectWifi(ssid,passwd): global wlan wlan=network.WLAN(network.STA_IF) wlan.active(True) wlan.disconnect() wlan.connect(ssid,passwd) while(wlan.ifconfig()[0]=='0.0.0.0'): time.sleep(1) return True H=None M=None S=None def get_time(): global H global M global S URL="http://quan.suning.com/getSysTime.do" res = urequests.get(URL).text j = json.loads(res) list=j['sysTime2'].split()[1] H=int(list.split(":")[0]) M=int(list.split(":")[1]) S=int(list.split(":")[2]) def data(M,S): for m in range(M,50): for x in range(S,60): This content is created by EEWORLD forum user youxinweizhi, if you need to reprint or use it for commercial purposes, you must obtain the author's consent and indicate the source

1. I'm curious about how you found Suning's time json interface. 2. What about the weather temperature shown below?

Two questions: 1. Can ESP8266 drive a 5110 screen? This is the first time I know this. Thanks for your advice. 2. ESP8266, what IED did you use to develop it, eclipse? Or something else? Is there any faster way to develop it? I feel that my progress is quite slow when I do it privately.

1. As long as the IO is sufficient, it will be fine. This method is not advisable. The IoT module should have the gameplay of the IoT. 2. As for the IDE, just use whatever you are comfortable with. I use whatever I have on hand.

Why do you say this method is not advisable?

If all monitored data is posted to the server, wouldn't it be more convenient for the entire mobile app?

Oh, I thought you said that the IO drive 5110 screen method is not advisable. I thought you had other ways to drive the 5110 screen.

May I ask which port of the ESP8266 should the 5110 screen be connected to? Thank you!
