We believe that the open source operating system Linux is the best platform for embedded control systems. We have realized several projects on our own Linux hardware featuring an ARM processor from ATMEL. We designed specialized I/O hardware, wrote the necessary drivers and the application software as required by our customers. Also we fixed several bugs in the operating system before the ARM version became stable. With Linux inter-operability never becomes an issue. One can always connect or extend its features with hardware and/or open source software. In case of problems the source code is available to analyze and fix the issue.

This Linux board has been designed for controlling industrial screw-driving applications as a master controller. Application software for communicating with and visualizing of the industrial process has been written. The board has been subsequently used in other client server an data acquisition applications. Due to the open source nature of Linux we were able to change and extend the functionality of device drivers. Also new device drivers were written for the user-specific I/O interfaces.
