[CanTp] Vehicle Diagnostic Communication Part 23 [Simulation 11]

I changed the FC equivalent to change the behavior of can-isotp multi-frame requests.The behavior is now compliant with the specified STmin.The time parameters for communication are wide enough to allow for synchronization between systems.If it is more than 10[ms], we aim for 11[ms] to ensure that it meets 10[ms] or more.

In the default state of can-isotp, the DLC optimization specification is adopted.If you set padding and MIN_DLC in the parameters passed to CanStack, it switches to the padding specification.

The FC's add up in python-can.Supported by inserting CAN frames with a bit of timing in python-can.This allowed the multi-frame request to go through for now.

[CanTp] Vehicle Diagnostic Communication Part 20 [Simulation 8]

The Python package can-isotp can communicate ISO15765-2, or ISO-TP.However, python-can must also be installed due to dependencies.For now, SF (SingleFrame) transmission is possible.The multi-frame transmission stopped at FF (FirstFrame) and ended in an error.The protocol specification is that the next sequence cannot proceed unless FC is received after FF.

CAN transmissions were replayed in can.player and recorded in can.logger.There are three file formats recorded by can.logger.asc, blf, and csv.

I installed python-can.Checked the operation of python-can.Sent by can.player and recorded by BusMaster.The performance of python-can is on the order of 1-2[ms].CANoe has better accuracy.

Finally, we get into Python.I'll use Anaconda, but you can use the official Python for Windows.You'd better make sure each one works! (I keep telling myself that…)

We are tired of studying and it's time to do some simulations.I will also do AUTOSAR related things.I will also dare the challenge of using Python.

【入門】状態空間モデルをPID制御(Python)【数値計算】

MATLABでやったDCモータ状態空間モデルをPID制御をPython(Numpy)で実施。Pythonの場合、構造体はclassで実現。事前にclassを定義する必要はある。MATLABと同様の結果が得られた。
