For our customers telos develops systems-based software on the innovative and free operating system Linux. At the moment there are two main aspects of development:


Device Drivers

For some projects hardware is needed for which the manufacturer does not offer Linux support in the form of device drivers. In such cases telos can develop device drivers for such 3rd party hardware. We can also develop device drivers for hardware, which has been developed by the customer especially for a project.
