[Gumstix-users] USB Port

From: Andy Lch <lauchea2@ho...> - 2007-10-24 15:45

Attachments: Message as HTML

I have a few questions that the community wiki didn't really clarify for me=
 (http://docwiki.gumstix.org/Verdex)
=20
As a hobby project, I'm trying to build a Gumstix (Power seperately by 9v b=
attery from the types similar to a remote control car)) to go with Roomba a=
nd a camera (Webcam is most likely).
I'm considering what I'll need before I start to buy the parts.
The Verdex board have 24 pins, 60 pins and 120 pins.
I'll need wifi to communicate with the base station (PC) when it is in oper=
ation and accomodate a USB for the webcam
Using the tweener's serial port I can upload the source code from pc to gum=
stix
=20
=20
So that means I have to have the following (If any other suggestion please =
let me know):
Verdex motherboard
Tweener (60 pins on both side, it sits between boards. Therefore the 60 pin=
s is still free)
NetwifimicroSD-EU (120 pins)
Robostix (60 pins)
=20
=20
Basically I have used up all the crucial connectors (Except 24 pins) availa=
ble to me from the motherboard.
And thus far none of the above mentioned boards have a USB host connector (=
Physical connector) on the board.
The only info that has the word USB related is from the verdex board itself=
 on Gumstix website.
An article on wiki did mention that I can use the 24pins line to make a USB=
 from it(http://docwiki.gumstix.org/USB_24_Pin)=20
=20
=20
Assuming I have to make one myself, I'm guessing that by soldering the wire=
s as shown in the wiki link to the corresponding pins will suffice?
=20
=20
Is Robostix crucial for controlling the robot? Or will the Verdex be enough=
 to control it.
What is the difference between it and the motherboard that already have pro=
cessor on it?
=20
I was thinking if I don't have to use the robostix, then I can use the Cons=
ole board which has a MiniUSB built in. What do you guys think?
=20
=20
This may be way too deep into the end of my planned project.
But how does the gumstix normally start? Is it based upon the power being s=
upplied (I.e on when battery is powered and off when battery is cut)?
=20
Any help/comment would be deeply appreciated (Thanks in advance)

If the Roomba has an embedded processor on board, you should be able to
talk to it over a serial port, so just use a console-vx, or a
consoleLCD-vx.

Yes, that's pretty much how it works. I generally use a switch that
disconnects the + lead from the battery. You can buy the power plug from
Digikey (CP-012-ND) if you want to make your own cable from the battery.

Later,
Jon

With the roomba, the robostix is probably not required, unless you're
adding some external motors or sensors. Even then, you could use a
console-vx board, and connect the robostix up via i2c.

I like the console board much more than the tweener.

Hi Dave,

Well, I will be using the onboard sensor from roomba but I will add a camera to 
the gumstix but I guess that will be taken care of by the USB port on the 
gumstix

You were saying to use the Console board and then connect the robostix up via 
i2c.. Is that running the robostix as a stand alone unit and powering it 
seperately also?

So what you're suggesting is getting the Console will replace the tweener and 
it will communicate with the robostix & roomba as well as having USB already 
premade for the camera?

In that case I'll probably need two 9v battery. where one will power the 
gumstix and the other powering the robostix

Yes - that would be running the robostix as a standalone unit.

Yeah - although I haven't done anything with USB cameras myself.

I wouldn't recommend using 9v batteries. The voltage is too high, and
you'll be wasting most of it due to thermal losses.

For the gumstix, you could use 4 x 1.2v NiMH rechargables, and for the
robostix, you could use 5 x 1.2v NiMH rechargables.

You wouldn't need the robostix unless you have some specific
sensors/motors that you're going to connect up to it.

The other option is to use something like I'm using, which is a 5 volt
switching regulator to get the 9.6 volts from the battery down to the 5
volts the gumstix requires, without wasting a lot of power.

I use the one from Dimension Engineering:

http://www.dimensionengineering.com/DE-SW050.htm

Its got a really nice form factor, and it doesn't cost much for what you
get, and doesn't require any external components.

Jon

[Gumstix-users] Other means of logging into gumstix

From: Anil Dhyani <anil.dhyani@pa...> - 2007-11-08 03:49

Hi Dave,

I want to know that are there any other menas of logging into gumstix other
than the serial .

Your initial help was indeed a grat one i am able to start up my code
compilation.

Thanks
Anil Dhyani
