OBD - On Board Diagnose

Embedded in technology refers to the use of embedded systems, which are specially developed computers to fulfil specific tasks within a larger system. These systems are an integral part of the hardware and are often used in everyday devices such as household appliances, cars, medical devices, industrial machines and consumer electronics.

An embedded system typically consists of a microcontroller or microprocessor that is responsible for controlling and monitoring processes. It often works with real-time operating systems (e.g. FreeRTOS) that enable a precise and fast response to external events. Another feature of embedded systems is their specialisation: unlike general computers, they are optimised for a limited number of tasks, which makes them particularly efficient and reliable.

The software in an embedded system is often tightly integrated into the hardware (hence the term “embedded”) and is usually written in low-level programming languages such as C or assembler, less often C++, to ensure maximum control over the hardware. This makes it possible to optimise the use of resources such as memory and computing power, which is particularly important in resource-constrained environments.

Overall, embedded systems play a central role in modern technology and especially in a control-unit. They are the silent “brains” of many devices that make our everyday lives easier, increase safety and improve efficiency.
