and communication methods from the ASAP2 description file, and are Via the ASAP1b interface the standard connection of the control units. ASAP2 Lib is a powerful and easy-to-use function library, which you can use for reading and writing standardized ECU description files in ASAP2 format for your . The ASAP2 Tool-Set consists of 6 programs for creating, checking, updating, merging, A2L files that are not standard-conformant can also be read-in using the.

ECU calibration with ASAP2Demo/ASAP2Library

Today, software development is highly distributed. Furthermore, the standard contains a description of the device interface to the ECU for read and write access. Definition of a binary large object for calibration not measureable. You must supply the rest by using Simulink data objects in a workspace or data dictionary. Furthermore, they can work with the ECU data in a familiar representation without having to understand ECU-internal data formats such as scaled integers, bit-fields or ID-codes.


Using XML would have otherwise increased the file size by approximately five times, which would have caused severe performance issues with tools that process such files. The standard defines the syntax and semantics of the data descriptions.

For example, using ExportedGlobal configures the data item as an unstructured global variable in the generated code. Calibration means the adaption of scalar constants, curves and maps to achieve an appropriate and optimized system behavior. See Data Access for Prototyping and Debugging.

Our newsletter informs you when a new standard version is released. Parameters and aggregated keywords may be mandatory or optional and may have a multiplicity. The following list contains the keywords of this level. Parameter objects, the table gives the associated property name.

Calibration and measurement variables can be hierarchically grouped via various means to support function-oriented calibration. Parameter to provide the information. Can be used to define calibration objects, which are part of a structure.

Information that is not needed for calibration such as code details is excluded.


Description of one memory segment of the ECU. Group hierarchies can be expressed that include a root and sub-groups. The first version of the standard was developed before the foundation of ASAM e.

For this purpose, internal variables are read from memory and transferred to a system that displays the data in a human-readable format. If no encoding is specified in the a2l-file, then ISO Latin-1 is assumed.

Indexing method to distinguish different variants, e. Don’t have an account? Used to resolve near-pointers in record layouts or to select the data set among several variant data sets.

Specifies general parameters of a module i. Specifies a conversion formula to calculate the ECU-internal value from the physical value. When all standards are jointly applied, then the MCD tool-chain achieves a high degree of interoperability, vendor- and technology-independence and allows easy exchange of data between customers and suppliers.

Since linker map files vary from compiler to compiler, you might need to modify the regular expression code in asap2post.
