I am trying to access a touchscreen directly connected to a PXA320,
i.e. using the internal touchscreen controller of the PXA.

With an osziloscope, I can see the sequencer working and I see that
the analog voltaxe changes, depending on the position on the screen.
However, I never get a useful readout from the ADCs.  Does anybody has
an idea or, even better, a code fragement for that problem?

Best regards,
