Sensors?

Hi, I'm really excited about the Mini2440v2 board. However before I order
my first board, I would like to know if I could read somehow temperature
and humidity sensors? I see there are no analog inputs. So I guess I have
to use SPI, 1-Wire or something? But somewhere I read there is no SPI and
GPIO driver in the Linux core for this board. Please, excuse me if I'm
wrong. I need to get sensor data like temperature, humidity and digital
on/off sensors. Is this easy achievable with Mini2440v2 and Linux? 

Thanks in advance,

There is an on-board ADC.  And yes, you have some work getting SPI and GPIO
going but there are a number of tutorials describing the process.

Have a look at this:

I tough that ADC is used for the touch screen.

I know there is an Angstrom build for Mini2440. Is there a chance the GPIO
and SPI is exposed in Angstrom?

One channel of the ADC is used in the demo software written by FriendlyArm
that comes on the mini2440.  Like you say most of the ADC is tied up with
the touchscreen.  I'd used a separate ADC run off SPI.

GPIO is more exposed in Angstrom as they enable sys/class/gpio, see:

and the left hand search button will turn up a lot more traffic on ADC and
GPIO on this site.
