Using ezTime with nodemcu-32s w/64x32 HUb75 LED Matrix about eztime

[Pius171]

I will need to see more of your code, in order to help.
Have you tried printing to the serial monitor, to see if the time changes?

@heffnerm2 , your void event function is inside the void loop, you can't create a function inside another function

Also, there are some errors in the void loop. Did this code compile?

[heffnerm2]

I cleaned it up, yes it does compile and run. I get the displays i expected Temp and Humidity inside and outside and time/date, but it does not update time/date
