hi ,
i want to build a new digital clock with a procesor and need your knowlege.
what procesor would work for it????? would arm be quik enough????
can i use a 32,768 hz watch crystal???? but would it make it slow??????
all help will be kind.

Why would it not be?
Thnk about it: all a digital clock needs to do is to count up by 1 every second, and remember that every 60th second counts 1 more minute, etc...
Even an 8051 would be overkill for that!
You could do it (and many have done it) with just a few basic counter chips!
electronics.howstuffworks.com/digital-clock.htm
In fact, you probably should do it first with basic counter chips - so that you really understand the foundations of what's going on.
Once you really understand how it works, it will be easy to implement in software on a microcontroller...
The original compiler was written in Oberon by Niklaus Wirth (the designer of Pascal, Modula-2 and Oberon etc.) to run on the Oberon operating system. I translated the compiler to Component Pascal to enable it to be run on Windows.
The original compiler assumed that the entire target application was running in RAM. I had to rewrite the parts that accessed globals so that resulting applications could run out of the mixed ROM / RAM environment of the LPC2000 family.
That was the hard part.
The remainder of the work entailed implementing an LPC2000-specific linker, integrating the whole lot into the IDE that I had previously written to be used with Component Pascal:

and adapting the language-sensitive features of the IDE to Oberon-07.

But still no idea how to do a simple digital clock!
With seniority, comes forgetfulness. He might have forgotten more than most here have every known. Who are we to know?
The advantage is that what has been once known should be easier to learn again.
can u give me some time i will build one for u with 7 segment calunder. i am busy with "c" now. by the way which topology u want, multiplex or shift regaster and also cpu.

Do you really think that insulting people will make them more willing to help you?
engineriing
I'm sure you did not mean "engineering", right? Going up the ladder I guess - soon you'll probably be designated "master chief engineriing programer etc. etc. etc."
There are a lot of professionals on this forum. Here's how you can tell who the professionals are:
A professional in need of help will: -provide a clear and concise statement of their problem, including design goals, examples of code, and SPECIFIC points of failure of THEIR design. -READ AND UNDERSTAND the help that is given to them by others. -Implement the changes suggested by others and provide DETAILED feedback about what works and what doesn't
You, sir, have done NONE of these thing in this thread or any of the others you have started.
So how long should we let Worldwide Chief Master Mind Executive continue with this joke?

I was thinking the master chef was sounding a bit like a 419 scammer, or this thread was something like scam-baiting.
Haven't seen the post about his rich Nigerian uncle/cousin/associate yet though.
:(
There is probably this competent and productive company that can do consultancy jobs within all fields - 30% up front, 50% on delivery and 20% on customer acceptance.
Right now, we are only seeing the sell-in phase where the technical lead presents himself and convinces us that he is representative for the company.
Looks interesting. I should have one or two LPC21xx board laying around somewhere. Maybe I should take a closer look at the release candidate during christmas.
I suggest you look at the Pawn scripting language. I discovered it not so long ago when I was looking for a scripting language for my application. It's small, fast, well documented, has a nice IDE, easy to use - it's (almost) perfect when you want to make your device programmable by its users.
