ADC Inputs

Hi all;

I bought mini-2440 3.5" and I'm about get my hands on the GPIO part and
analog input part. 

Now, I look at the datasheet and then the circuit boards to search for the
AIN terminals and found none. Then I came on this forum to see if I can get
any help. Many people here talk about AINs of mini2440, which makes me
believe that I'm stupid enough to miss some very simple thing. 

Am I stupid or do you guys have a special add-on which I don't know?

Please help....

Think most of the ADC inputs are used for the touchscreen.  FriendlyArm use
one ADC input for their ADC demo application.

I suggest this thread:

and doing a search on the forum.

The S3C2440 CPU has 8 analogue input channels, four of them are used by the
touch if the touch is to be used. The remaining AIN0...3 are available at
the CON4 at pins 5, 6, 7, 8
