As you wrote, it’s a lack in portability, but might be the way to go during migration of an existing ECU. 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. Services are not, they should in general be available on any ECU. While there are some commonalities between Services and Complex Device Drivers, there are also a number of rather large differences:. Some of my questions are below,. The service components in Arctic Core does exactly this and may be used as inspiration when writing the service interface for the complex driver. Only difference is SWC type.

The most forward approach here would be to directly let the CDD interact with the hardware. 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.
All files related to the complex driver should be located in the project and not in the Arctic Core folder. Created and last modified by Michael Lundell on Mar 17, Arctic Studio Integration Arctic Studio provides a powerful way of designing complex devicce to make them available as any other BSW module.
These parameters can then be assigned application specific values in the phase of ECU configuration.
Thomas Zurawka Premium Moderator. I will try to present you answers to your questions but please note that the answers are most probably neither complete nor authorative. There is no such analogon for CDDs. Author and commenters Dr.
The main purpose of complex drivers is to add support for complex sensors or actuators. Older ddevice may deviate in details, but all-in-all the answers should apply to them, too.
Complex Device Driver Development for AUTOSAR Compliant Powertrain ECU
But in short term, we need to compromise in some aspects to go ahead with my proposal. The generator, check, and stylesheets should be located in the project and not in Arctic Core.
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 devoce.
The only file that heeds to be included to use a BSW module is the corresponding header file. The service components in Arctic Core does complrx this and may be used as inspiration when writing the service interface for the complex driver.
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. Document generated by Confluence on Apr 13, Arctic Studio provides a powerful way of designing complex drivers to make them available as any other BSW module. This means that the configuration is separated into configuration files that are included by the actual complsx files.

aurosar 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.
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. It is encouraged to follow these recommendations and this document also describes the capabilities of complex drivers in further detail. As the function depth is more, the time taken to execute this may be more.
Both of these are possible. How do we differentiate?
Is there any reasons to remove these operations and configuration parameters? However, you have to carefully balance the gain in performance with your customer’s e. Some of my questions are below. How to access SPI Handler? Only visible to XING members. As you said, we xutosar the runnable entity in either case. Another reason for doing so may be extreme performance requirements.
