Barcode reader with PIC16f877A ?

[skimask]

oky, my barcode reader type is "PS/2 Keyboard Wedge Barcode Scanner" and I test it with my PS/2 PC port , which when i insert the ID card it's automatically display the number "120063718" with new line

I know that the problem is how to know how encoding is done ?

Then you'll probably have to get a list of the actual PS/2 scancodes relating to various keypresses, numeric, alpha, whatever. Probably throw all of those into a lookup table, crunch the table and get your keypress out of it.
Basically, you're building a PS/2 keyboard reader. I'd be willing to bet that if you found some PS/2 reader code somewhere for plugging in a standard keyboard, that it would actually work.

I will thank you another time for your patience, I understand that you are meaning that I can replace my barcode reader by a keyboard and pressing the same ID number to know how each number is encoding

oky i will try this

That would be my bet.
So in the end, you're project would be (with enough info in tables or whatever) a capable PS/2 keyboard reader.
But I'm guessing here...and it makes sense to me.

Push 1 once...write down the sequence of bits returned...push 1 again, compare the sequence to before
then push 2 once, write down that sequence, etc.etc. and so on...

What do you get on the display for a single press of the number 1 on the keyboard, one press, one release of that single key...not the numeric keypad, but the number 1 above the Q?

I found the barcode reader specifications after a period time of searching
here is the link

my barcode reader model is SSR-2110

but the manual is in franch i don't understand that

What did you come up with? Anything?

Not going to read it, not going to attempt it, that's your job. Besides, I don't know french...

By the datasheet, if your reader is SSR2110, it use the regular PS/2 interface.

There's few code example to read/decode/interface PS2 keyboard here

There ya go...he knows french

Although that datasheet was sparse if it's anything...(even I could figure out some of those crazy words )
