sysfs

http://lxr.free-electrons.com/source/Documentation/filesystems/sysfs.txt

What it is: ~~~~~~~~~~~ sysfs is a ram-based filesystem initially based on ramfs. It provides a means to export kernel data structures, their attributes, and the linkages between them to userspace.

sysfs is tied inherently to the kobject infrastructure. Please read Documentation/kobject.txt for more information concerning the kobject interface.

IIO

Adapted from http://wiki.analog.com/software/linux/docs/iio/iio

The Industrial I/O subsystem is intended to provide support for devices that in some sense are analog to digital or digital to analog convertors (ADCs, DACs). Devices that fall into this category are:

• ADCs
• Accelerometers
• Gyros
• IMUs
• Capacitance to Digital Converters (CDCs)
• Pressure Sensors
• Color, Light and Proximity Sensors
• Temperature Sensors
• Magnetometers
• DACs
• DDS (Direct Digital Synthesis)
• PLLs (Phase Locked Loops)
• Variable/Programmable Gain Amplifiers (VGA, PGA)

ARM AT91SAM9260B

http://www.atmel.com/devices/sam9260.aspx

A 210MHz ARM926-based processor with an extensive range of communication peripherals. It embeds FS USB host and device interfaces, a 10/100 Ethernet MAC and an image sensor interface, as well as standard peripherals such as a Multimedia Card Interface (MCI), I2S, USARTs, master/slave SPIs, 16-bit Timers, a TWI and four-channel 10-bit ADC. The external bus interface features controllers for SDRAM and static memories including NAND flash and CompactFlash. The SAM9260 is available in 217-ball LFBGA and 208-pin QFP packages.

FXOS8700CQ

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=FXOS8700CQ

Freescale’s FXOS8700CQ 6-axis sensor combines industry leading accelerometer and magnetometer sensors in a small 3 x 3 x 1.2 mm QFN plastic package. The 14-bit accelerometer and 16-bit magnetometer are combined with a high-performance ASIC to enable an eCompass solution capable of a typical orientation resolution of 0.1 degrees and sub 5 degree compass heading accuracy for most applications.
