Hi Jonathan,
I wonder why the documentation is specific to accel?
I think that can be many things...
What: /sys/.../device[n]/buffer/scan_elements/accel[_x0]_type
KernelVersion: 2.6.37
Contact: linux-iio@xxxxxxxxxxxxxxx
Description:
Description of the scan element data storage within the buffer
and hence the form in which it is read from userspace.
Form is [s|u]bits/storagebits. s or u specifies if signed
(2's complement) or unsigned. bits is the number of bits of
data and storagebits is the space (after padding) that it
occupies in the buffer. Note that some devices will have
additional information in the unused bits so to get a clean
value, the bits value must be used to mask the buffer output
value appropriately. The storagebits value also specifies the
data alignment. So s48/64 will be a signed 48 bit integer
stored in a 64 bit location aligned to a a64 bit boundary.
For other storage combinations this attribute will be extended
appropriately.
Greetings,
Michael
