Problem with MicroViewDemo - would not compile
The 4th line in void setup()
“setTime(10,10,01,17,1,2014);”
gives the following error
“ ‘setTime’ was not declared in this scope “
How do I modify the sketch to make it work?

Hi Tonygo,
Quote from [http://learn.microview.io/intro/getting-started.html
If you wish to compile and upload the MicroViewDemo from our example, there is a [3rd party Time library that is required to be installed. Download the Time library and use the same library installation method discussed above to install it into the Arduino IDE. [/quote]
Hope this helps.
Cheers
Thanks. I’ve re-installed Time library and it now works.
Regards
Tony
Hello having exact same problem … Time library is there but sketch won’t compile.
The learn.microview.io server link dead.
Error is:

OK so for Arduino IDE 1.8.2 on Macintosh (if that matters) solution is:
Get new Time library from Github (or get the entire Teensy thing from https://www.pjrc.com/teensy/td_libs_Time.html )
The Github link is https://github.com/PaulStoffregen/Time
I got the zip Time-master.zip and it became Time-master folder.
The Time library version appears to be 1.5
Replaced contents of Documents/Arduino/libraries/Time with contents of Time-master
In MicroViewDemo replaced #include <Time.h> with #include <TimeLib.h>
This solution also works for MicroViewAnalogClock. Used an external editor to make permanent change to the example code (the Time.h to TimeLib.h mod).
