Subject: [Gumstix-users] What Gumstix and Expansion boards to get?

 

Hi All, Please excuse my ignorance! :)

 

I'm a researcher at the Human Media Lab at Queens University in Kingston,
Ontario, Canada.  We are working on a project, that involves a flexible
Zytronic Touchscreen and an Android cell phone.  I need to interface the
screen with the phone.  Unfortunately Zytronic only supports Windows and
Linux, and to top it off, even if I could get the touchscreen to work with
Android, I'm already using the USB port to output to HDMI.

 

>> Why don't you use a small 4 port USB hub or splitter cable ? It will give
you more USB ports .

 

So I need to come up with a solution that involves connecting the
touchscreen to a Linux device, and then communicating the x-y events from
Linux to the android device.  

 

Also, size is a factor.  So that's why I'm looking at Gumstix.  Oh yah. Time
is also a problem. I need everything in place for February 1st.

 

>> I don't see how you are going to write the code in that time, given the
learning curve L

 

Connectivity between the Gumstix and Android will be done using Bluetooth or
802.11, and I need a USB OTG/Host connection to connect to the Zytronics
controller.

 

>> There are a number of posts about Bluetooth that should help. Also check
the Wiki.

 

So, from the product page, it looks like I'll need a Tobi Expansion board,
and Overo Air or Fire board, and the relevant connectors.

 

>> If I was you and had the $$ I would also order a Summit board. It is
smaller and you can use it for the final project. Use the Tobi for
development because it has 10/100 conectivity

>> for installing file from the internet.

 

Am I going on the right path? Could you give me some assistance here?

 

What I would suggest is that you 'compile locally' (on the Gumstix) It is
less time consuming than building the OE.

Also go get Steve Sakoman's 'desktop image'. It will give you a GUI for
development. All you need is a hub, keyboard, mouse and HDMI monitor.

There are plans for a development system on my web site at:
www.williamprettysecurity(dot)com.

 

Time is of the essense, and I'd like to order something in the next day or
two.  

 

Good luck J

 

If a phone call would be better to discuss, let me know, I just need to get
something going. :)

 

Thank you,
