AT/PS2 Keybord - PIC Interface?

Yeah, your code seems to indicate that you are waiting for the clock line to do something?

Your device must generate the clock in this case.

Ok, I misunderstood.

I now realized that you are SENDING data TO KB;
Not reading from it.

Sorry about that.

rookie11, I don't think this code will ever work. Where are the ENDIF commands to terminate the IF statements?

One line If/Then statements....don't need an ENDIF....

If this=0 then gosub dothis : that=1 : goto something

...valid statement
If this is zero, then gosub dothis, set that to 1, then goto something.

But that colon following the THEN in the code a few posts back looks a bit strange to me...
And I know colons!

Well, I was talking about the code attached above. He has this line (along with another that's the same way):

If scancode.0 = 1 Then: parity = parity + 1
----------------------^

I don't know how that'll compile, if it will compile good and not cause an error, if it'll work as written, or what will happen. It just doesn't look right to me, that's all...

And I'm always keeping track of where my colon's lie...

skimask, The way I interpret a colon is to terminate a line of code and, allow the start of another command string to be placed on the same line. If this is the case then all of his IF/THEN statements should have and ending ENDIF command. I have not tried this as I never write code in this fashion. It is much to confusing and hard to follow the flow... Have you ever tried this format? If it works then GREAT...
