DS3232 and PIC....

[Wond3rboy]

Hi i am trying to program the DS3232 to generate an interrupt every second. But even after following the right directions, it just isn't getting done. I can generate a square wave of various frequencies but am not able to generate the Alarm Interrupt per second.

Delay1KTCYx(500);// Let the RTC Startup
	Write_DS3232(Control,0x85);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Seconds,0x00);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Minutes,0x00);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Hours,0x12);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Day,0x01);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Date,0x01);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Month_Century,0x01);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Year,0x10);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
[B]	Write_DS3232(Alarm1_seconds,0x80);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Alarm1_minutes,0x80);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Alarm1_hours,0x80);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Alarm1_day_date,0x80);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC
	Write_DS3232(Control,0x05);
	while(SSPCON2bits.ACKSTAT!=0);// wait for ack from RTC[/B]

I want you guys to look at the bold lines of code. According to the Datasheet of the DS3232(PG# 12) I have written 1 on each of the Four Bit masks but for some reason the RTC is not generating an interrupt every second. All Data Transfer routines are correct. They are working.

Thanks.

Hi, i checked my code with the example given in the application note.

**broken link removed**


I found that i have written the correct code and there is some problem with the Proteus model(already told my university to complain to the Labcenter Guys). Well since i had written the code, i continued with it and instead of using the alarm interrupts i have used the square wave feature(added the necessary substitutions for Alarm interrupts).Here is the code and the simulation in proteus. I would have made it in hardware but i dont have no $$$ .
