Services are not, they should in general be available on any ECU. Some of my questions are below.
However, often you might want to use a CDD because you need to access a very specific piece of hardware for which no defined module in the MCAL exists. Older revisions may deviate in details, but all-in-all the answers should apply to atuosar, too. As you said, we need the runnable entity in either case. Documentation for Arccore Autosar 4 solution version 4.
The service components in Arctic Core does exactly this and may be used as inspiration when writing the service interface for the complex driver.
Complex Device Driver Development for AUTOSAR Compliant Powertrain ECU
The recommendations includes a file structure that is very similar to any other BSW module. Manually configuration The configuration files and ArText files may of course be created and edited manually without using Artic Studio.
I will try to present you answers to your questions but please note that the answers are most probably neither complete nor authorative. Another reason for doing so may be extreme performance requirements. 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.
Arctic Studio Integration Arctic Studio provides a powerful way of designing complex drivers to make them available as any other BSW module. 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, All files related to the complex driver should be located in the project and not in the Arctic Core folder. How do we differentiate?
Introduction to Complex Drivers
The only file that heeds to be included to use a BSW module is the corresponding header file. But in short term, we need to compromise in some aspects to go ahead with my proposal. The complex drivers may have three different interface categories: However, you have to carefully balance the gain in performance with your customer's e.
As the function depth is more, the time taken to execute complx may be more. The path is included when building projects so the headers files may be included without any path.
Only difference is SWC type. Thomas Zurawka Premium Moderator.
It is very useful for CDD implementation. In any case, such a decision needs considerable investigation of the concrete project at hand.
Documentation for other versions of Autosar 4 solution is available too. The configuration files and ArText files may of course be created and edited manually without using Artic Studio. That header file includes all types and configuration files. Author and commenters Dr. How to access SPI driver? 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.
This means that the configuration is separated into configuration files that are included by the actual implementation files. 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:.
Both of these are possible. What you might save in development cost short-term, you might lose long-time in terms of maintainability and portability.
