LED display. has any one made any code that alows someone to display A-Z, 0-9

MMISCOOL

I was wondering wether any one has made a program that alows some one like me to debug in a character into a byte variable and diaply it on an led display. LED. not LCD.
thank you
if any one has pleas post it with any diagrams and parts you may have used

Ok first you need to specify if you are using a 7 segment LED (looks like 8.), an alphanumeric (a * inside a box) or a matrix. If its the first, you cannot display all letters, K,M,Q,R,S,T,V,W,X and Z cannot be displayed in an easily discernable shape.

I am talking about an led display similat to the one shown below

they sell this one thrue www.allelectronics.com and becouse it is cheep i am thinking of geting it.

MMISCOOL

I think all the leters of the alfabit can be displayed on the led display above. has any one done something like this?

Russ Ferguson

Yes.
It will take 15 I/O pins to directly control all of the LED display segments on that display. That doesn't leave much for anything else unless you multiplex the I/O or get one of the bigger stamps.

That one only takes 14 I/O pins. the comon one I just have to conect to ground or -. I am just wondering wether any one has done anything like this so that mabe i can do something very similar instead of having code for each individual leter

But coding is so much fun!

You can't learn to program better without programming yourself.

Just like:

You can't learn to spell without reading and using a dictionary. For instance, I will make the effort to go to dictionary.com to look up words that I can't spell. It works great. And it makes those that read things you type happy, and more likely to help you.

Have an early christmas, attached is a pdf·I created for your display. I cannot be sure the codes are 100% correct, but there shouldn't be many errors, let me know if there are so I can correct them.
