+static struct attribute *ads1110_attributes[] = {
+ &iio_const_attr_sampling_frequency_available.dev_attr.attr,
+ &iio_dev_attr_sampling_frequency.dev_attr.attr,
+ &iio_dev_attr_scale_available.dev_attr.attr,
+ &iio_dev_attr_scale.dev_attr.attr,
scale wants to be done via infomask element of the iio_chan_spec and
relevant element of a switch statement in read raw. That way it will
be available via the inkernel interfaces (once we pin down exactly
how they will be registered - another discussion entirely...)
Here I need some help.
I looked at the ad7793 driver how to do this. If I understand it right,
this driver also has the possibility to change the scale.
I changed read_raw and added write_raw to the ads1110 driver. When I
test the driver on my hardware I'm not able to set the gain, there is no
sysfs attribute for it (on the board runs a 3.1 kernel with a backprot
of the driver).
Best regards
Pirmin
