Currently only for AVR but ARM coming soon.

Requires: Boolean support found on libstock

Easy access to all RTC functions including RAM read / write as well as RTC output. Has "daylight savings time" support. This is the current law for dst, but future revisions will allow for a custom dst if the law were to change.

Several functions exist in this library including GMT HTTP header output for your web server project.

Example:

#include "ds1307.h"

#include <stdbool.h>

#define msg( txt ) UART1_Write_Text( txt )

void main()

{

ds1307_config_t rtc;

rtc.time_zone = -8;

rtc.dst_enable = TRUE;

rtc.config = DS1307_SQW_1HZ;

UART1_Init( 38400 );

Delay_ms( 100 );

ds1307_init( &rtc );

EICRA |= (1<<ISC01) | (1<<ISC00);

EIMSK |= (1<<INT0);

SREG_I_bit = 1;

}

void rtc_sw_ISR() iv IVT_ADDR_INT0 ics ICS_AUTO {

msg( ds1307_get_system_time_str() );

msg( "\r\n" );

}

NOTE* Time is kept in GMT on the hardware. Local time is supported through "time_zone".
