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 (see Get Code Description of Generated Code).
