This NOT PicBasic nor does it use a Pic but it does do what you want and since source is available, you should be able to extract the
descriptors - http://blog.flipwork.nl/?x=entry:entry081009-142605.

One common piece of advise when dealing with descriptors, is to take a working example and make incrementally changes, testing with
each iteration.

Hello George,

Thank you so much for your help .

You are right when you say to get a working example and do some changes.
That is what i'm trying to get...a working example.

All the examples i get here do not compile and i dont know why.
The one i posted ( descriptor ) is from this forum and it was suposed to be working but it does not compile

If someone would explain me why this does not compile maybe i would be able to fix it and move to the next stage.

Regards

Any chance you could post the errors? Some of the people around here can often narrow the issue when seeing those.

Greetings,

Thanks...you are right...

If i compile with the descriptors commented i get these:

	' Include	"DESCKB.ASM"	' Include the HID descriptors

If i add the descriptor include it will open the desckb.asm file and outline in red lines in it.

Also...

I'm using these 2 files + all of the files inside the USB18 folder from PBP.

As far as I know all the samples in ..\USB18 will compile (I just tried a couple to confirm). One thing that often goes wrong when I use PicBasic is that I forget to set the correct microcontroller.

You are right when you say to get a working example and do some changes.

The point is that you start with working descriptors.

Hi there,

One thing that often goes wrong when I use PicBasic is that I forget to set the correct microcontroller.

Not in this case...i have the correct microcontroller selected.

The point is that you start with working descriptors.

Exactly, like i said in my first post.
My problem with the PBP examples is that i'm having problems correlating them with the other examples posted all over the forum ( that dont compile here ) and therefore make the necessary changes to keyboard.

Too bad PBP does not have keyboard demos
