hi guys
i already made the propeller display using 89c51.

i must say that this project is really amazing!!!
Now i need to modify the program for 3 different modes.
1. Analog clock display
2. Digital clock display
3. Message mode display.

i want to do it in real time. And i need help with the code.
Please help me with the code and circuit diagram for it. I am currently working on the code and will post it here shortly. But i also need help with modifications in the circuits so as to
1. Change the modes
2. Set the time in both analog and digital
3. To enter a message using an interface.

i really want to make this happen guys so please help me out.

and please please reply with any suggestions , links or codes that may help.

@ Shehwar
make a separate code for each mode and then test it
when test is ok for each mode after that u can make a final code
that will combine the 3 modes in this way coding and debugging will be easy for u

trickry part is to make the clock hands on runtime... digital clock however is simpler... you can try making it first

Ajay Bhargav


Ajay has a point.
Making a digital clock is relatively easy, making an analogue clock would be a challenge
even for an experienced programmer.

my problem is not in making but in changing the program as you understand... I have the propeller display project ready with my name displaying on it i just need the editing part in program so as to create a clock.
I will use one of the ports to set the time.

Shehwar


By "making" I meant programming.
To get the analogue effect of moving hands you need to light certain LEDs
as the display rotates...sounds complicated.

yes hence i am trying for the digital first.
I have a code for it but it is for a pic.
Do you know what modifications must i do in order to make it for 89c51 ?

well the only difference here is that you will have display test to be generated on runtime rather than stored on a specific location. so instead of reading from 600H location (current code is written to read string from this location) read from ram where you clock time is present.

i suggest use DS1307 RTC so you can have real time clock whenever you power on your display. read from RTC, store in ram after converting to ascii.... figure out what need to change i gave you lot of hints and ideas hope to see some progress now good luck..

ajay bro i have another suggestion
instead of going through the trouble of using 2 pcbs, 3 relimate connectors...
can we use 1 single pcb for the entire circuit ?
If so can we use the dotted pcb to make it happen ?

and as far as the 3mode part is concerned, i have some info on the code for a pic and i have no clue as to what that is.
FYI this was my 1st microcontroller based project .
So can you help me with the changes in code ?

i really have no idea what you're talkin about i mean in what context.. you can build as you want.. just make sure you dont modify the circuit

FYI this was my 1st microcontroller based project .
So can you help me with the changes in code ?

Shehwar


First is always important in life... First project means you will learn a lot.. and by the way.. i think i helped a lot with hints in my last post. You better understand the original codes, get comfortable with assembly coding then start with project. here on this website you will always find people ready to help.. but you cant expect anyone to give you ready codes.

Hello, I am planning to do simulaton of the ' 4-way traffic controller'. As a first stage of the project, I tried to compile the code given in this website in keil microvision which controls 4-way traffic . I am using AT89C51. But when I am trying to compile the code it shows an error " Device is not supported by Toolchain". Can u please help me...
