Then today, after loading different sketches onto the NodeMCU, and then returning to the clock, it now displays ‘–:–‘ instead of the time in every zone.

It’s possible I’ve made some minor change to one of the library components (while experimenting with other sketches), but I don’t know where to start looking, since the clock’s operation is so obscure (all the real work is done by ‘invisible’ modules, buried in libraries somewhere).

It would be nice to have a detailed explanation of the sketch, and what modules do what functions.

Any suggestions about where to start looking for the cause of my problem?

Thanks,
DanielF

Thanks for posting it!

But I’m struggling to understand the timezone stuff, given that it’s all ‘hidden’ deep in some library somewhere. Perhaps you can give me a few tips…

If I change:
String timeZoneIds[] = {“America/New_York”, “Europe/London”, “Europe/Paris”, “Australia/Sydney”};
to:
String timeZoneIds[] = {“America/San_Francisco”, “Europe/London”, “Europe/Budapest”, “Australia/Sydney”};
all four screens display –:– in place of the time. So are only the original four timezones supported by the library, not the full 600+ zones?

And I can’t find where to change the duration each page (city) is displayed. How can I do that?

I’m an absolute beginner at this Arduino/NodeMCU business, so please keep your answers simple. 🙂

Daniel

Hello,
Arduino 1.6.7 works pretty good, if you place prototypes of your functions in *.ino in front.
It's the simple solution for error "…was not declared in this scope"
That's all.

I don't know convert file .png to hex, could you guide me. Please. I'm not good speak English.

Arduino IDE Version 1.6.7 and 1.6.6 are currently not supported by the ESP8266 platform. Please use 1.6.5

When compile the examples, the compiler stop with this:
exit status 1
'drawFrame1' was not declared in this scope
I am using Arduino version 1.6.7. Any idea?.

thank you very much for publishing the sources for this nice project. Here is my (stripped down) version ->

The displays that I'm using have the I2C address "hard coded". I guess if you would switch the bridge transistor on the back of the display you could run them from the same two pins. I just ran them of three different I2C bus pairs…
