Data Structures
struct	tm_rtc_t

Functions
ssize_t	ds1904_check_family_code (uint8_t *rom)
	Verifies that the family code stored in rom first byte belongs to the driver supported device. Data read is CRC8 checked before a success is reported. More...
uint32_t	ds1904_date_convert (tm_rtc_t date)
	Converts a date to epoch time. More...
ssize_t	ds1904_date_update (uint8_t *rom)
	Reads the RTC time-register and updates global time. More...
void	ds1904_get_date (tm_rtc_t *date)
	Returns current date and time from RTC. More...
ssize_t	ds1904_read (uint8_t *rom, uint8_t *config, uint32_t *time)
	Reads configuration and time registers. More...
ssize_t	ds1904_set (uint8_t *rom, bool_t enable)
	Enables or disables RTC's oscillator maintaining current time value. More...
ssize_t	ds1904_write (uint8_t *rom, uint8_t config, uint32_t time)
	Writes configuration and time registers. More...
