Replace GPS module with radio-controlled clock module #1

Open nopizzaa opened 2 years ago

First of all, this project is amazing!

Could you make a solution to replace the gps module with a inexpensive dcf77 (it specific to my region), or with any other radio clock module?

GPS location is used to calculate sunrise/sunset times. If switching to a dcf77, the sunrise/sunset feature would need to be dropped from the display.

For many people, this tradeoff would be acceptable and could implemented via compiler flags, but it's not something i would probably get to anytime soon.
