Display as second monitor

Roibert:
Dear Forum

Actually we have ralized a device ,with a  microcontroller PIC24, able to be used as a Touch pad , using the HID class . So ,when we touch this ares, we can see on window the pointer to move
All without writing any driver on window.

Now, we would like to create a display, driven by some microcontroller (ST or PIC),that ca interface with window...that means, window must see it as a monitor.

We see that there is not some HID class for this.

We understood that the UVC class is only for receive video data from a camera, and
visualize on window....but this is not what we want.

So, question are :

1) What means for window to be a second monitor ?

2) Actually we are able to transfer data via winusb ,in bulk mode.. This seems nice for video because of bulk. Can be usefull .

Thanks
Roberto

Synaptics has a chip that supports USB monitors. It uses a host driver provided by Synaptics.

Thanks Mr Jan for reply

we would like to understand the mechanism of how window can render images on a USB display. Clarify idea is for us important.

Thanks
Roberto

Jan Axelson:
This would require writing or buying a host driver. I don't know where to find documentation on how to do this.

Roibert:
Many Thanks for your reply.

Now We know better how difficult this could be,and we will decide what to do.

Thanks
Roberto
