[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.

[CanTp] Vehicle Diagnostic Communication Part 18 [Simulation 6]

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.

[CanTp] Vehicle Diagnostic Communication Part 17 [Simulation 5]

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…)

[CanTp] Vehicle Diagnostic Communication Part 14 [Simulation 2]

We installed Vector's free XL Driver Library and Vector Driver Setup. There is an application called xlCANControl in the XL Driver Library, so it is a quick way to check the operation. You can assign channels to each app, so you need to assign them in VectorHardware in the control panel.

[CanTp] Vehicle Diagnostic Communication Part 13 [Simulation 1]

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.

[DoCAN] Vehicle Diagnostic Communication Part 12 [ISO-TP 8]

ISO15765-2 (UDS) and ISO15765-4 (OBD) have different values for the timeout parameter. The UDS side is looser and the OBD side is stricter. Some timeout parameters are set as performance requirements. N_Br and N_Cs.

[DoCAN] Vehicle Diagnostic Communication Part 11 [ISO-TP 7]

ISO-TP has six timeout parameters. N_As, N_Bs, N_Cs, N_Ar, N_Br, and N_Cr. Single frame transmission is complete in one frame, so only N_As. Multi-frame transmission uses all parameters. ISO-TP only determines the timeout at the frame level, and the timeout per message is determined by a higher layer.
