Adapter for connecting an embedded system to a control computer, and method for adapting an adapter

An adapter for connecting an embedded system to a control computer, the adapter comprising:

• a standard interface;
• a first subcircuit;
• and
• a second subcircuit, the first subcircuit being configured to communicate with the control computer via the standard interface via a standard protocol or the universal measurement and calibration protocol XCP,
• wherein the first subcircuit is connected to a second subcircuit via an internal interface,
• wherein the second subcircuit has a programmable computing module which is configured to provide at least one elementary function out of an overall set of elementary functions which can be called up via the internal interface via a call,
• wherein the first subcircuit is designed to convert one or more values received via the internal interface into a protocol format of the standard protocol,
• wherein the second subcircuit is connectable to the embedded system via an individual interface,
• wherein the first subcircuit comprises a programmable logic device and a non-volatile memory in which a fixed configuration of the programmable logic device is stored,
• wherein the first subcircuit converts a protocol functionality requested in the standard protocol via the standard interface out of a set of supported protocol functionalities into the call for one or more elementary functions out of a defined overall set of elementary functions, and
• wherein the second subcircuit comprises a user-writable memory in which the binary code of the programmable computing module is stored.
