I have started to write a driver for the ADC of the Atmel AT91 series
controllers. I will test it on an AT91SAM7SE controller. When it is
ready, I will send the patch so that it can be included in eCos.
Is anybody interested or is there anybody who works on the same thing?

It seems that the ADC is generic to AT91SAM devices (I checked SAM7S,
SAM7A3, SAM7L and SAM9260), they differ only in supported values for
trigger sources, channel number, etc. I think I will write a driver
that can be used with the Generic ADC driver layer.

When adding the ADC defines you first need to determine what level
they go. Is the ADC controller specific to AT91SAM7 or is it generic
to all/many of the AT91 devices? It does look like many different
AT91SAM devices have ADC controllers. I took a quick look at the
AT91SAM9XE128 and it seems to have the same ADC controller. Maybe also
the AT91SAM7L devices use the same controller?
