I'm trying to connect a USB webcam to an Arduino board (Intel Galileo), the Galileo is powered by a 400 Mhz processor, has 512 Mb of RAM and 8 Gb of external storage (SD Card). I'm a computer science major and electronics is not really my field, what I understood to this point is that if this was a serial connection I would've used the first and second (0 and 1) pins to make the connection (Rx and Tx). Now I understand there is a difference between USB and serial, but USB is somehow serial? Anyhow I've attached both a picture of the camera cable and of the board and would appreciate the most simplified way to make the connection. Thanks!enter image description here

  • \$\begingroup\$ "USB" is serial, and "serial" is serial, but "serial" is actually "UART". \$\endgroup\$ – Ignacio Vazquez-Abrams Dec 20 '14 at 21:27

    \$\begingroup\$ "Serial" is purely a concept, not a protocol. In the same way that "vehicle" covers cars, lorries, trains, planes, etc... \$\endgroup\$ – Majenko Dec 20 '14 at 21:27

  • \$\begingroup\$ It's an Arduino See : arduino.cc/en/ArduinoCertified/IntelGalileo \$\endgroup\$ – user3601592 Dec 20 '14 at 22:28
  • \$\begingroup\$ @user3601592 it's "Arduino Certified"...but it's not an Arduino. \$\endgroup\$ – Grant Dec 21 '14 at 4:28

Plug the camera into the USB host port.

The Intel Galileo documentation says it has a USB host port, which is labelled 'USB HOST' on the PCB. Plugging a keyboard or mouse into this port (using a standard USB cable) will allow it to be used with the USBHost library, so doing so with a camera should also make the correct electrical connections.

You will then have to use linux and OpenCV to support your camera as in this thread, or search for "intel galileo usb camera" online for other examples.

  • \$\begingroup\$ Thank you for replying, that's actually a micro-usb port and webcams are using a "standard" USB 2.0, can you help me with that please? \$\endgroup\$ – user3601592 Dec 20 '14 at 22:29
  • \$\begingroup\$ @user3601592 buy an adapter. \$\endgroup\$ – Pete Kirkham Dec 20 '14 at 22:33
  • \$\begingroup\$ Would that work for sure? (This project started to drain my resources) \$\endgroup\$ – user3601592 Dec 20 '14 at 22:37
  • \$\begingroup\$ I'll be installing a Linux image later on so are you sure this will work? Thanks \$\endgroup\$ – user3601592 Dec 20 '14 at 22:41
  • \$\begingroup\$ @user3601592 searching for "intel galileo usb camera" brings up this thread communities.intel.com/thread/48204?start=0&tstart=0 where various people have various issues, and also details of which particular adapter. \$\endgroup\$ – Pete Kirkham Dec 20 '14 at 22:43
