Generated Code Interfacing

Tune parameters and measure signal data by using ASAP2 and C API interfaces and view generated code metadata

Some applications must exchange data between generated code and external application code. Use the ASAP2 and CDF interface to establish a communication channel between development and target computers, export an ASAP2 file containing description format of the internal ECU variables, or export a Calibration Data Format (CDF) file containing the information about parameters in a machine-readable format. Use the C API to exchange data between generated code and external code.

To obtain metadata about the generated code, use the code descriptor programming interface.

Sample Target Environment Service Implementations of Data Communication Methods shows samples of how target environment services might implement the three types of data communication methods: direct access, outside execution, and during execution.
