The function here:
Line 169 in d1b3066
Returns a dangling pointer to a buffer that was allocated on the stack. The function should be taking in an output buffer pointer as an argument instead.
I used the value 946684800
and it seems to have the correct time.
OLED display driven by Adafruit_SSD1306 (https://github.com/adafruit/Adafruit_SSD1306) not working completely with this version of DS1307 library.
Adafruit fork RTClib (https://github.com/adafruit/RTClib) working fine with OLED display, but does not provide time formating options. :-(
bool DS1307::isLeapYear(uint16_t year)
{
return (year % 4 == 0);
}
The correct algorithm is:
if (year is not divisible by 4) then (it is a common year)
else if (year is not divisible by 100) then (it is a leap year)
else if (year is not divisible by 400) then (it is a common year)
else (it is a leap year)
