AT90S2313 | AT90S8515 | ATMega | ATmega128 | ECL | FETS | IAR | Keyboard | LCD | STK50 | TMOS | UART

Mind you have said the following
name, part number, and breif description

like;
Real time clock
1302
DS1307
DS1337
DS1338
DS1339
DS1340
DS1375
You can not beat the information I just found at
http://para.maxim-ic.com/en/results.mvp?fam=rtc

But I am still think of adding a Atmel folder to my web site to add in my
own notes and make available to other member get up to speed faster

Hi all

The pictures are added in under Photos/Event scheduler.

Thanks

Hi Sahil

This is a simple event scheduler that I build. It has a RTC (1302), NTC 10K
temperature sensor. The NTC is uncalibrated now and showing the adc value of
528. I need to work on it
to read in degree C should not be more half a days job.

The clock time setting and relay on/off time can be fully controlled through
the four push buttons in front while reading the LCD. (Please read the Date,
it is fresh from oven).

I am working on a simple tutorial on migrating from C to winavr and the
functions for this project.

I have coded using winAVR and on ATMEGA328P bootboard. The Board has on
board bootloader which communicates with AVRStudio4 for flash and eeprom
downloading/ uploading. The advantage is that I have running RS232 all the
time and can make use of ISP pins as I/O. The date and time can also be set
through PC Terminal (rs232).

My simple advice on project of this scale.

1) All informations are available in datasheets. Believe me if you were to
program this on your own you will have to read the datasheet over and over
again many times like me.As far as I remember I have not posted a single
technical question ever on any forum but yes have replied to many. But I
agree that I am doing it for hobby(with > 10 years uP programming) and some
of you must be doing it for your tight time schedule project. But still
instead of getting ready made solution it is more fun to program it yourself
and believe me sometime it is faster.

2) As many have said before do it a small step at a time. Just send string
of "Hello" on RS232, just show one A at the corner of LCD panel, just get
the changing second for DS1302 never mind even if it is still in 1999 this
would have crossed the main hurdles that is the communication would have
been established with the device.

3) If you are using winAVR or any C, do not underestimate the power of
modular programming and pointers.

The main components that I have used

1) LCD JHD 162A
2) RTC 1302
3) AVR ATMEGA328P bootboard
4) NTC 10K

I hope above can help you a little in your project.

Thanks

Sharma

I got this

http://www.futurlec .com.au/ATMegaCo ntrolBoard. jsp

ATmeg32 you also get software to download the program

You will also have to get
. DS1307 Real Time Clock: (there is a IC soket for it on the board)
. In-Circuit Program Downloader

If you use some other board they have a Real Time Clock (RTC) boards
http://www.futurlec .com.au/Mini_ DS1307.jsp

They also have another web site
http://www.futurlec .com/ATMegaContr olBoard_Technica l.shtml

I am not sure what else is available out there, (closer to ATmega16)
I thought this clock would be neat it displays date & time on a standard 6
digit clock
http://www.dubdubdu b.net.nz/ clock/
sorry I can not do the 7-segment font
