Hi,
I have seen the board described in this link.
http://www.seventech.it/english/merlinoboard/2.php
I think that its a good solution to realize an embedded system with VGA
output, in that cases where, to use the PC, is not convenient.
I have seen that it's available also a dev kit to develop the code in C++
and it is not necessary to use an operating system.
How is it possible to work with a system without operating system?
You thing thought of it? Is it really a good product? Who has used this
board?
Thanks
Renato

What are you intending to use it for? An OS is not needed or even desirable
in many embedded applications. Development is done cross platform on a PC
or something then the application is downloaded to the target. Looks like
this board is
intended for the video game market.

Doug,
A company has commissioned a control panel for boats.
This board seems very proper. They includes in the Dev Kit library, also a
class to connect the touch screen. I could use the bus I2c to connect all
the board services with only 2 wires.

Renato,
I looked at the web site. The board seems to be generic.
A price wasn't given, (or I didn't see it), but for $500/600
one can get a variety of single board computers.
As usual, the devil is in the details. How good is the
development system? How complete is the library? Is the
compiler and debugger included, or are they a $3000- $5000
add-on?
I've had good luck with smaller microcontroller modules, such as
Z-World...cheap...easy to use...easy to design in hardware-wise.
Of course they aren't very suitable for high-speed work...50mHz and up.

Depending on your background in most cases I've found it easier to use
a generic tiny x86 board (e.g. mini-itx, mini-atx, or others) running
Linux or WinCE. If you're used to writing apps that run on operating
systems these will offer you a familiar development environment with
good libraries for IO, threading, etc... and for a very good price
point.

I'm most comfortable working on Linux so for prototyping a headless box
I'll often start off with a Soekris board (e.g.
http://www.soekris.com/net4501.htm ) because they run off of 12V, are
very inexpensive and reliable, then I'll add a compact flash card for
the OS, install an embedded Linux distro (e.g.
http://www.nycwireless.net/pebble/ ), and start developing.

Anyhow, just another alternative to consider...

I have seen the boards that you recommend. But they doesn't have a VGA
output or perhaps have not I attentively read?

IT sounds like it is probably a good board for that application. As far
as connection to other services, I2C is only intended to connect devices
close by such as on the same PC board (inches). Not a good communication
infrastructure throughout a boat.

What standard for communication infrastructure do you recommend?
