invalid conversion from 'void (*)(void*)' to 'void (*)()' [-fpermissive]

I'm getting an error on line 454:

trCheckNtpServer.every(TR1H, checkNtpServer, (void*)0);

Error messages:

I have to comment it out to compile and upload.

Which Timer lib do you use? I forgot to add link to timer lib to Readme (fixed). You should use: https://github.com/JChristensen/Timer/tree/v2.1

Yep, that sorted it. Thanks :thumbsup:
