STMicroelectronics has simplified the use of MEMS in a wider range of applications by releasing ready-to-use software drivers for communication with Linux systems.
STís new driver architecture is supported in the latest revision of Linux Kernel (from revision 3.9), which is available immediately: the drivers make STís 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 surveillance.
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 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.
Key features of STís 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
