生成代码接口

使用 ASAP2 和 C API 接口调节参数和测量信号数据，并查看生成的代码元数据

一些应用程序必须在生成的代码和外部应用程序代码之间交换数据。请使用 ASAP2 和 CDF 接口在开发计算机和目标计算机之间建立通信信道，导出一个包含内部 ECU 变量描述格式的 ASAP2 文件，或导出一个标定数据格式 (CDF) 文件，其中包含机读格式的参数信息。使用 C API 在生成的代码和外部代码之间交换数据。

要获得有关生成代码的元数据，请使用代码描述符编程接口。

Sample Target Environment Service Implementations of Data Communication Methods 显示目标环境服务如何实现三种类型的数据通信方法的示例：直接访问、执行期外和执行期间。
