Hello Everyone..
I want to interface rtc ds1307 with pic18f452 to make an alarm that will sound once in a day...instead of giving it to a buzzzer i want to control a relay from it...
I want to develop the code in embedded c language...can anyone help me...?

How far through are you in developing the code? Where are you stuck in developing the code?

You should upload whatever you have worked on, or mention any references you are using (eg. any website, book, etc).
 

You need to know I2C interface to read/write the registers of RTC chip. What IDE you are using? mikroC has built in library. Otherwise you have to download I2C library.

Tahmid is correct.
Read I2C interface, read datasheets etc.
Do some work and then ask help. Otherwise you will not learn anything.

Click to expand...

You can also write the functions/subroutines for the I2C operation without external libraries after going through the datasheet and a little bit of practice. This isn't going to be too difficult since the 18F452 has an I2C hardware module.

If you decide to code it yourself, you might find it fun and also learn something while you're at it, although it's going to take longer.
 

Yup i will be soon posting the program..as i am currently tryin to develop it...

can anyone provide me with some urls or ebooks on pic18f programming using c language..?
 
As for free stuff, there are a few tutorials here:

https://pic2learn.wordpress.com/
https://www.pic18f.com/

You should go through the reference manual: **broken link removed**

The book by Mazidi, the datasheet and the Reference Manual should be all you need. For other help, just use Google or post your queries here.

Hope this helps.
Tahmid.
 
Can you provide me with all the functions and details of rtc ds1307?

Thanks..
