[CanTp] Vehicle Diagnostic Communication Part 37 [Simulation 25]

Fixed the script for Python can-isotp requests. The request is now ISO14229-1 compliant. Implemented AUTOSAR-CanTp side. The response is now SO14229-1 compliant as well. The code has not been published yet for personal reasons.

[CanTp] Vehicle Diagnostic Communication Part 36 [Simulation 24]

We defined a concrete configuration structure for AUTOSAR-CanTp. The number PduId is used when interacting with CanIf. In this case, the following. 0: Transmission of 0x18DAF110. 1: Receipt of 0x18DA10F1. 2: Transmission of 0x18DA10F1. 3: Receipt of 0x18DAF110. The Receive Control Block for CH_RX_CB and the Transmit Control Block for CH_TX_CB are for work.

[CanTp] Vehicle Diagnostic Communication Part 35 [Simulation 23]

The configuration structure of CanTp is described in the AUTOSAR specification. However, there is no UML description. The update priority may have been lowered since it has been followed since the OSEK era. This time, we will define the corresponding structure entity manually without using a configurator.

[CanTp] Vehicle Diagnostic Communication Part 34 [Simulation 22]

CanTp is based on the concept of a pair of transmitting and receiving channels. Channels can be duplicated. However, dynamic duplication is not allowed. Only static duplication is possible.

Windows10(64bit)でMATLAB 2012b のmex setup(コンパイラ環境構築)

※ レジストリをいじるので、本記事をもとに作業する場合は自己責任でお願いします。 MATLAB 2012bの64bitコンパイラ環境はVisual C++ 2010にする必要があるのだが、 Windows10においてはVisual C++ 2010且つ64bitコンパイラを用意するのはかなり難儀した。 自分自身の忘備録として残しておく。
