Parallella as a Standalone or Embedded Device?

Postby adeshpande » Thu Jul 03, 2014 8:38 pm

I am pretty new to Parallella so these might be pretty simple questions that I'm asking so bare with me.

Do I connect all of the cables into a laptop's ethernet port, USB port, HDMI port, etc? (I think this is called using it as an embedded device)

Or do I connect all of the cables into a separate monitor, a separate mouse, an ethernet outlet in the room, etc? (I guess this is called a standalone device)

Does the choice between either of these 2 options affect the installation procedure?

Thanks

The Parallella is meant to be used "stand-alone".

Can it work as an embedded device as well?

I'm not quite sure how useful that would be. Let's discuss the individual interfaces:

HDMI: Does your laptop (or PC) really have an HDMI input? It sure has an output port so you can use, say, a projector or a dedicated computer monitor on your laptop, but using the laptop to display the Parallella's screen via HDMI seems strange (but see below for an alternative).

Ethernet: you could configure your laptop to share an Internet connection via the Ethernet port. But why not give the Parallella it's own access to a wireless network or an Ethernet router?

USB: not sure why you would want to connect via USB.

I think what comes closest to your idea of "embedded" would actually be to set up the Parallella "headless", so without it's own monitor, keyboard, mouse, and just connect it to the same network as your other computer(s). Then you would use a software like VNC to display the Parallella's desktop in a window on your PC/laptop. But that would work via the network (Ethernet or wireless), NOT by connecting via HDMI.

"Embedded device" usually means you're putting it into some sort of system, like a car. You can do that with the parallella, but I don't think that's related to your question.

I think what you're asking is whether you can use it headless - without keyboard, mouse, or monitor.

It can just be plugged into an ethernet hub or switch (or router which contains one of those) and accessed from a remote machine. The only thing to determine or configure is the IP address on your network. It should just boot from the sdcard up once power is applied.

This is how i've been using mine so far.
