Propeller Display using AT89C2051

Sir could you please tell me how to power the circuit when the motor is rotating? I have asked this question previously also but didn't get any reply till now. Please reply me ASAP

I think this has already been answered. There are two ways,
one is you can connect a ring on the base of rotating assembly and ring is connected to a bush which provides supply.

second method is to power the rotating assembly with a batter mounted on the opposite side of controller. This removes adding weight on the other side as battery will manage the balance of rotating assembly. And the motor can be powered from external source so your battery can work long time.

sir
i want programme code in C language
plese post shortly

hello sir
i have a few requests
1. Can someone please post images of the backside of the assembled pcb.
2. I need the program for an analog clock in asm or c language.
3. I want to make the propeller display but i need it to be interfaceable with a keyboard or a decimal keypad without using pc.
Please admin reply to my queries....

@ Shehwar
try to do urself these requests
and where u get problem u can post here the peoples help u
do not aspects that anyone will work for u

does anyone know the code and circuit to convert it to a digital clock?

i need to modify it so that i can set the time.

@ Shehwar
once i was thinking this but due to shortage of time i not do this
if u can that its good then u can share it here
first u has to understand only that how characters are being displayed on it
after that i think it will be easy for u to set it as a clock

bro i dont know how to write a program. i have yet to understand interfacing and programming.
hence i asked the help of experts!!!!
i told you that i've already built the propeller display but my idiot professor is hellbent on forcing me to make the propeller clock
and i dont know how to
hence i request you to help me out.
please try to do so.....

@ Shehwar
ok first let u know about the logic that how it display
for a while leave that u want clock
now u has to understand how data is displayed on led's
this is a basic point

i told you that i've already built the propeller display but my idiot professor is hellbent on forcing me to make the propeller clock
and i dont know how to

Sorry Shehwar, we don't write code for people, we help them write
their own code.
Your professor set you this task to make you learn to program.
Even if we supply the code he will ask you how you did it, so you might as well
just learn.

A clock is not that hard to make.
The AT89C2051 crystal makes the AT89C2051 run at a precise speed.
The propeller code will have a timer set to interrupt many times a second.
In that interrupt increment a count.

When the count reaches a certain level a second has passed.
Increment a "seconds" count and then a "minute" count and so on.

This way you count hours,minutes and seconds.
Display the counts and you have a clock.


It is better to stick to your other thread, so that answers can be related to each other.
