Noob question: Ask before I buy

Hi there,

I just recently had a bad experience with another board using Debian
linux. My application is instrumentation for an all-electric
vehicle. What I need is some low-level code reading serial, SPI, I2C,
and other buses as well as some nice graphics to display things like
gauges and graphs. I'm thinking the Beagle Board would be good for
this. Can anyone enlighten me before I buy one? Here are a couple
questions:

1. Is there a standard 2D graphics package supplied with Angstrom that
I can use out of the box. If so, what is it and what do I need to use
it? Is it double-buffer such that I can update frequently without
flicker?

2. I'd love to use the board with a 6-10" touch screen lcd panel. I
see there are USB panels advertised on the BeagleBoard site. Has
anyone used one of these panels? Did you have good luck with it?
What sort of frame rates were you getting?

Thanks in advance. After my last experience I'm trying to make sure
to do some more advanced research before jumping in. On the other
hand, I'm eager to get started.

Thanks!

There is that DevKit8000 which is a BeagleBoard based design..
there is also those ARM9 board on Ebay from Hiteg, there is a
US distributor at http://www.andahammer.com. I have one it
will run a linux kernel has drivers and will run either qtopia
or Angstrom but its a little short on flash / ram to run Android..
The 7" display + board is a little cheaper @ $170 incl shipping.

If you are interested, I have one slightly used but in great shape
that I may be interested in selling, I can even throw in the Ubuntu
VirtualBox image with the compilers set up and the kernel ready
to compile..

SDL is a good library, http://www.youtube.com/watch?v=TUYOjRGYeYU

double buffering, low level, i have my own drivers that write to the fbdev but this is what SDL is doing, plus its decently cross platform.

haven't used a usb panel unfortunately.

Hi Charlie,

Is there a SDL package for Angstrom on BB?
If not what's the easiest way to install it?

Yes, it is.

Thanks,

Now I see there is a few libsdl* packages.
Do I need to install all of them to run luvcview?

Hi,

I was able to install all libsdl packages into my BB.
I was able to build luvcview (http://www.quickcamteam.net/software/
linux/v4l2-software/luvcview/)
using native compiler on BB.
When trying to run it, I have a 'segmentation fault'
Is anyone able to run luvcview on BB?
