Ok, it sort of has been asked before.
Their library offers "sunrise" and "sunset" times.
These would be handy for my clock as it would get the Sun rise time and adjust the brightness as needed. Likewise for the evening when the sun sets. Dim the display.
There are 2 versions. _S and _W
Both come with an "include" and "time" directory which I am guessing need to be compiled, or what ever.
Alas that is beyond what I know how to do.
One even has an .EXE file in with it.
Sorry, but I am needed a bit of help how to make either of these two versions workable with my setup so I can use the library in my clock for display brightness adjustments.
Thanks. (Oh, not sure how quick I will be replying to responses, as the notification doesn't seem to be working.)
