digital clock using 8051

hi all,

i need to make a digital clock by using 8051 microcontroller in assembler

and the display is seven segment not LCD
no decoders used

there are 3 switches :
1- one for modes ( hours,minutes and seconds)
2- the second for alarm
3- and the other for stop watch if possible

Any ideas?

thanks.

Sounds doable, what's the problem?

hey.........
are you talking about real time clock for the controller whhich shows the current date, & time.........
 
source code for a digital clock with 8051

There are two methods to make a clock:
1. Use timers for counting the seconds and increase some variables wich will be your minutes, hours, etc. This is not so accurate
2. Accurate method use some RTC (real time clock) chip, e.g. from Maxim Dallas. They've them on i2c or SPI

thanks to all

Ok , No problem
by using real time clock. can u help me in source code?
but remember the display is 7-segment not LCD

Regards
 

digital clock using microcontroller

For an accurate clock
you have to calculate the delay of exact one second
depending on the frequencu of your microcontroller
and also depending on the internal clock divisor.
you have to also take into account the machine cycle an instruction will require
Regarding 7 segment interfacing it is easy using microcontroller

i know that 7-segment interfacing is easy
but i need the source code in assembly language:!:

please help:|

thanks.

Hi
its so easy.
see the circuit i am uploading.
you may use a 8051 and RTC chip.
