Can I use this library on another microcontroller?

[FrancescoCrevatin]

Hi jpb10,
first of all: great job.

Meanwhile, I want to tell you that I used the library for an Arduino project and everything worked fine, only I found some problems with the "automatic" time calculation using: setTime (toUtc (compileTime ())) ;, so I used a clock (RTC) that gives time to the other function you created: setTime (hr, min, sec, day, mo, yr).

But I wanted to ask you, since I'm not very grasped in C programming and using libraries: Can I use the same library to write a program on another microcontroller? That is, I would need the same library in C, and it seems to me that it is in C, but I wanted to ask you for confirmation if I could use the exact same library on a microcontroller other than the Arduino family.

Thanks again for your availability.

This library isn't directly compatible with C, but here's a quick conversion: CSolarCalculator (zip)

Usage is slightly different:

calcSunriseSunsetFromDate(year, month, day, hour, minute, second, latitude, longitude, &transit, &sunrise, &sunset);  // or
calcSunriseSunsetFromUnix(utc, latitude, longitude, &transit, &sunrise, &sunset);

calcHorizontalCoordinatesFromDate(year, month, day, hour, minute, second, latitude, longitude, &azimuth, &elevation);   // or
calcHorizontalCoordinatesFromUnix(utc, latitude, longitude, &azimuth, &elevation); 

Notice the function names and & before each output.

Just wondering, are there certain features that are not available in the C version which are in the C++ version (except for the & thing)?

It's not currently up-to-date, but otherwise it's the exact same program.

And if you wanted to keep the same syntax, I think the C overloading technique described here could be used.

Thank you @jpb10. I'll try next days.
Thanks again for all the work you have done
