車両診断通信 [CanTp] Vehicle Diagnostic Communication Part 38 [Simulation 26]
Review of simulation configuration.Code handling on the virtual ECU side.Currently, it's private, give me a break.Confirmation of communication logs of SF-SF, SF-MF, and MF-MF.

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.

We experimented with changing FC parameters in can-isotp.can-isotp is highly complete.At least, it is much better than those vehicle diagnostic communication whose structure is broken.

We experimented with can-isotp request-response.SF-SF communication -> OK!MF-MF communication -> OK!

Most vehicle diagnostic communication is a single request-response communication.There are some exceptions such as request-only and response-only communication, but they are quite rare.Both the request and response sides are script fatted by the receive thread mechanism.

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.

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.
