STMicroelectronics Increases Accessibility of MEMS Motion Portfolio by 
Simplifying Connection to Linux Systems 
Linux Industrial-IO-Compatible Drivers for Entire ST MEMS Range
Shorten Development Time for Motion Innovations in Multiple Market
GENEVA -- (Marketwired) -- 05/02/13 --   STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers across the
spectrum of electronics applications, the world's top MEMS
manufacturer, and the leading supplier of MEMS sensors for consumer
and portable applications(1), has simplified the use of MEMS in a
wider range of applications by releasing ready-to-use software
drivers for communication with Linux systems.  
ST's new driver architecture is supported in the latest revision of
Linux Kernel (from revision 3.9), which is available immediately: the
drivers make ST's MEMS devices more easily accessible to developers
using Linux open-source software to build consumer, industrial,
scientific and healthcare applications with precision movement and
position sensing in multiple axes for uses such as remote monitoring,
test and measurement, robotic control, machine vision and
The new ST driver architecture ensures robustness, maximizes sensor
performance, and allows modularity and fast prototyping. Driver
access is managed through a standard IIO (Industrial-IO) interface
and no additional software is required to interface all the ST Motion
MEMS products due to the embedded IIO driver already available into
the Linux Kernel. 
"The ST IIO driver modules also provide the flexibility to exchange
all the ST MEMS devices without any changes at the driver level,"
said Paolo Bendiscioli, Motion MEMS Application Manager at
STMicroelectronics. "This solution allows faster design upgrades and
helps our customers improve time to market for their new products." 
The new driver architecture works with the full ST MEMS family
including accelerometers, gyroscopes, iNEMO inertial modules,
e-compasses and magnetometers, thereby enabling quick and easy
connection of any sensor with minimal software overhead. It allows
the system to recognize devices, access data, support interrupts and
perform polling data acquisitions. 
MEMS sensors are widely used in consumer products such as
smartphones, tablets and gaming devices for features like indoor
navigation, display orientation and gesture recognition. ST has over
800 MEMS-related patents and patent applications worldwide and is the
world's top MEMS manufacturer, with cumulative shipments of more than
three billion MEMS devices and production capacity of 4 million
devices a day. 
Key features of ST's MEMS Linux Industrial IO driver library: 

--  Optimized to support all ST MEMS device functionality
--  Code overhead reduction
--  SPI and I2C bus interoperability
--  FIFO embedded at driver level
