Does anyone of you guys happen to have a code for RTC displayed in lcd and works as an alam clock? can anyone help me with this one..im looking forward to it

 

For what controller?

Which RTC IC?

What output for alarm?

 

Sorry i forgot to mention that I'll use Pic microcontroller(PIC18F family), ds1307, 2x16 LCD..

 

With which compiler?

Do you have it displaying the current time on an LCD at the moment?

Have you worked with PIC before?

 

well i only know the basics. the only program that i coded is about blinking led and using the if else if..and a little of c..i use c18 compiler

 

There are several versions of code to get the LCD and RTC running already posted in several places on the net.

Is this application going to be portable, or powered by a wall adapter?

 

I want to make the motor run on a specific time that i wanted.. it's not portable

 

I'm making a pet feeder..so I want to make a system for it. set time when to feed.

 

Link to base, modify code to fit your compiler

Then it's just a matter of setting a time for the clock to be equal to. How simple or complex you'd like that is up to your taste. (menu to set alarm time, multiple alarms, etc)

The DS1305 Supports 2 alarms, but communication is through SPI rather than I²C.

The DS1337 supports 2 alarms with I²C communication.

This would allow the uC to be in sleep mode between alarm events.

 

So should I change the rtc that I'm using(ds1307)? But I guess I can't change the rtc I'm using..I dont want to dump the ds1307 its already a module type..here's the link please do check it out
