Embedded Software Development
Companies designing off-highway systems, including those for agricultural, forestry, and construction vehicles, often find schedules so aggressive that little time has been reserved for embedded development and its integration into a system. With DISTek, companies get the support and expertise of an embedded team that provides specialized experience in writing compact and efficient embedded software that adheres to standards such as ISOBUS.
The embedded applications that DISTek provides are easily maintained, and DISTek engineers help customers scale and grow over time by providing support, training, and on-site engineering services. DISTek has assisted in the development of hundreds of different embedded systems for ECUs, electro-hydraulic controls, vehicle networks, and operator interfaces and displays.
