I tried various optimizations:
1. response caching to answer to 3D frame as fast as possible
2. 3C request and 3D answer moved into a C library to minimize latency (in case python can't reliably guarantee milliseconds latency)
3. all other frames are forwarded to python and processed there.

Current ...

Thanks for the reply, but I'm still confused.

In my use case, the response depends on the 3C frame payload.
I.e. Master requests, in a burst:
RX ID: 3C Data: 02 03 22 00 04 FF FF FF CRC: D4
RX ID: 3C Data: 02 03 22 01 04 FF FF FF CRC: D3
RX ID: 3C Data: 02 03 22 03 04 FF FF FF CRC: D1
RX ID: 3C ...

Hi,we are developing a Windows application that aims to Simulate a LIN Pump.
The simulator acts as a Slave and must answer to requests from a Master board.
Master board requests multiple 0x3C packets with different SIDs and DIDs in a small amount of time (up to 10 requests per second)

Our suspect ...

sorry, wrong forum page. moving to PLIN-USB.

Some updates, maybe useful to others:

Wrong PID and Checksum => I was interpreting thing by the wrong protocol! It is not "transparent" LIN data, but lin message bytes wrapped into PCAN-LIN protocol described by https://www.peak-system.com/produktcd/Pdf/English/PCAN-LIN_ProtDef_eng.pdf ...

I recently bought a PCAN-LIN interface to communicate with a Master board.
I'm completely new to LIN
My target is to develop a LIN Slave Pump simulator running on PC (python 3.x).
I was expecting the adapter to be 'transparent' and be able to simply access the LIN bus reading/writing LIN frames on ...
