Drivers for Bitland Dual Accelerometer

Drivers for Bitland Dual Accelerometer

[Lasse Schuirmann]

Hi,

I'm trying to use Linux on a Lenovo Yoga 300 and can't get the
accelerometer running. It was suggested at
https://github.com/hadess/iio-sensor-proxy/issues/83#issuecomment-220399560
that I contact this mailing list as no driver seems to exist yet.

The device in question is an accelerometer from "Bitland Corporation"
with the APCI ID "DUAL250E".

Windows drivers seem to be available at
http://driverlibs.com/download/Dual-Accelerometer.

I wonder if somebody possibly has the same problem and/or would be
interested in helping getting this to work.

Sincerely,

Lasse Schuirmann

Hmm long shot but any idea if it could be a rebadged bma250e which is a Bosch
 sensortech part? Not sure what the dual bit would be about though.

Digging in those windows drivers may give us more info.  They are on lenovos
 website as well.

On phone right now but will have a look tomorrow.

Hmm. The driver in question is based on Microsoft's example 
accelerometer driver
for an ADXL345.

https://msdn.microsoft.com/en-us/library/windows/hardware/dn760713(v=vs.85).aspx

Not sure this is going to get us much further though...

No usefully named function names that I can get out of the 
DualSPDAccelerometer.dll
Not sure where to go next on reverse engineering this.  Are you willing 
to
open things up to take a look at what is on the board?

Few times I've gotten involved with doing this it's always been a case 
of getting
some probes on the chip.  There probably are other ways of doing it but
I've no idea how in windows!

My gut feeling is that Bitland don't make Mems devices so are getting it 
from
someone else.  Could be wrong, but it's someway from what their core 
business
seems to be (putting generic stuff together to make machines for other 
people).

This is not my device so I can't say definitely but I may well be able
to open it up once if you tell me what you're looking for as I'm not
much of a hardware person.

Pretty much playing guess which chip is the accelerometer - tend to be perhaps
3x3mm and see if it has a logo on the top or a more detailed part number.

Otherwise, I'm guessing the laptop no longer has windows on it, so
trying to snoop on bus transfers is going to be 'tricky'.

Hmm.  Anyone know how / if to snoop on ACPI calls in windows?
