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
Rui

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.

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

Sorry, forgot that PicBasic didn't have a keyboard example.

Let's just hope that some kind soul has a working HID Keyboard descriptor.

This is a long shot but in the USB readme it says that the descriptors for the samples are derived from the original Microchip Solutions package. I've attached the keyboard and mouse descriptors from that package (you can download them yourself from Microchip's site). Using the PicBasic mouse descriptor you have compared to the Microchip version and hopefully understand how to convert the Microchip keyboard descriptor.
