Welcome to the page of my (W.I.P.) project called

which is a smart clock that connects to a NTP server to get the current time. It uses a ESP8266 (devboard: Wemos D1 mini, soon i will make it work also for ESP32).

(ESPclock BOLD coming soon... 😉)

📜 INSTRUCTIONS

1. Install VSCode or VSCodium (i prefer VSCodium because it basically is VSCode but without telemetry);

2. Install PIOarduino extension on VSCode/VSCodium;

3. Download the latest .zip file that you can find in the "Release" section, extract it, then open in VSCode/VSCodium the ESPclock project directory;

4. Select the PIOarduino extension in VSCode/VSCodium, then you have to store the html page into the esp8266 flash memory in two steps:

   1. Platform -> Build filesystem image
   2. Platform -> Upload filesystem image

5. Now lets upload the C/C++ code. Again from the PIOarduino extension in VSCode/VSCodium, go to:

   1. General -> Build
   2. General -> Upload

6. Now let's connect PC or mobile to the ESPclock access point, with the password: waltwhite64

7. After connecting to the ESPclock's AP, open your browser and paste in the address bar: http://192.168.4.1/

8. From the web UI, first add your home network, then the NTP server that matches your region, plus the GMT/UTC offset hour(s).

9. And we're done! Hope that you liked my project! If you have any suggestions, let me know!

⚠️ TROUBLESHOOTING

There are (at the moment) two errors that can be displayed from the 7-segment display:

• Err0 -> when "LittleFS.begin()" fails
• Err1 -> when "index.html" doesn't exists in flash memory (user forgot to upload it)
