Review of Linux Compatibility

The Intel Play QX3 is a digital Microscope, which invites (not only) children to experiment with it. The microscope is recognized by Linux like a webcam and has a maximal resolution of 352×288 pixel.

The microscope is supported by the cpia driver which is part of the gspca driver. The microscope is automatically recognized if plugged into the Linux PC:

usb 2-1: new full speed USB device using uhci_hcd and address 6
usb 2-1: configuration #1 chosen from 1 choice
V4L-Driver for Vision CPiA based cameras v1.2.3
USB driver for Vision CPiA based cameras v1.2.3

  CPiA Version: 1.33 (2.10)
  CPiA PnP-ID: 0813:0001:0106
  VP-Version: 1.0 0100
usbcore: registered new interface driver cpia

The kernel module creates a new video device, which provides the video feed of the camera

ls -l /dev/video*

To control the microscope the pseudo devices /proc/cpia can be used

ls -l /proc/cpia/

This device accepts the following options:

bottomlight:                 off       off        on       off

The commands can be given to the pseudo device, e.g. to switch on the illumination of the microscope:

echo "toplight:on" | sudo tee /proc/cpia/video0
echo "bottomlight:on" | sudo tee /proc/cpia/video0

or to switch it off, respectively:

echo "toplight:off" | sudo tee /proc/cpia/video0
echo "bottomlight:off" | sudo tee /proc/cpia/video0
