Additionally you probably need to supply a small configuration generator module for the ECU configuration tool you are using, which can take the parameters as input and generate the C header or C source code output file required to actually configure your CDD source code driver on C implementation level. Another reason for doing so may be extreme performance requirements. Services are not, they should in general be available on any ECU. Only visible to XING members. But in short term, we need to compromise in some aspects to go ahead with my proposal.

Services are not, they should in general be available on any ECU.
This means that the configuration is separated into configuration files that are included by the actual implementation files. Only difference is SWC type.
Complex Device Driver Development for AUTOSAR Compliant Powertrain ECU
Some of my questions are below. While there are some commonalities between Services and Complex Device Drivers, there are also a number of rather large differences:. Created and last modified by Michael Lundell on Mar 17, It is very useful for CDD implementation.
All files related to the complex driver should be located in the project and not in the Arctic Core folder. Complex drivers may be integrated in Arctic Core either by using Arctic Studio to configure the driver or handling the configuration manually by editing the configuration files.
Both of these are possible. Documentation for other versions of Autosar 4 solution is available too. However, you may still require some Runnable Entities in order to access everything that is happening over the VFB interface, namely your CDD’s required and provided ports:. But either case are possible depending on the real time application needs.
As the function depth is more, the time taken to execute this may be more. The only file that heeds to be included to use a BSW module is the corresponding header file. Another reason for doing so may be extreme performance requirements. How to access SPI Handler? The recommendations includes a file structure that autossar very similar to any other BSW module.
I will try to present you answers to your questions but please note that the answers are most probably neither complete nor authorative. Older revisions may deviate in details, but all-in-all the answers should apply to them, too. The most forward approach here would be to directly let the CDD interact with the hardware. How to access SPI driver?
CDD implementation in AUTOSAR architecture – AUTOSAR | XING
As you said, we need the runnable entity in either case. Arctic Studio provides a powerful way of cokplex complex drivers to make them available comple any other BSW module. Manually configuration The configuration files and ArText files may of course be created and edited manually without using Artic Studio.
There is no such analogon for CDDs. But in short term, we need to compromise in some aspects to go ahead with my proposal. Based on the layout of your configuration parameters, you can select whether you want your parameters configurable at pre-compile time, link-time, or post build time.
The complex drivers may have three different interface categories: How do we differentiate? It is encouraged to follow these recommendations and this document also describes the capabilities of complex drivers in further detail.
What you might save in devce cost short-term, you might lose long-time in terms of maintainability and portability. This is probably the preferred way of working if configuration is limited and static.
That header file includes all types and configuration files. In any case, such a decision needs considerable investigation of the concrete project at hand. Author and commenters Dr. The configuration files and ArText files may of course be created and edited manually without using Artic Studio.
