Converting Arduino Compatible library to work with ESP32

[6v6gt]

The library does not do very much (for example, no alarms etc.). What methods from it have you used in your previous code ? It should not be too difficult to write a few wrapper routines for another DS3231 library which is already ESP32 compatible so that changes to your existing code are at a minimum.

public:
		DS3231(uint8_t data_pin, uint8_t sclk_pin);
		void	begin();
		Time	getTime();
		void	setTime(uint8_t hour, uint8_t min, uint8_t sec);
		void	setDate(uint8_t date, uint8_t mon, uint16_t year);
		void	setDOW();
		void	setDOW(uint8_t dow);

		char	*getTimeStr(uint8_t format=FORMAT_LONG);
		char	*getDateStr(uint8_t slformat=FORMAT_LONG, uint8_t eformat=FORMAT_LITTLEENDIAN, char divider='.');
		char	*getDOWStr(uint8_t format=FORMAT_LONG);
		char	*getMonthStr(uint8_t format=FORMAT_LONG);
		long	getUnixTime(Time t);

		void	enable32KHz(bool enable);
		void	setOutput(byte enable);
		void	setSQWRate(int rate);
		float	getTemp();
