Usage on windows with any hardware about python-udsoncan HOT 3 CLOSED

Hi,
UDS is only one layer (application layer) in the communication stack. It is normally used over a transport layer, usually IsoTP (ISO-15765). This project only handles the UDS part (there is a another repo to that handle IsoTP). It is not dependent on the operating system, you have the possibility to build the underlying layers yourself.

The way this project handle underlying layers is through an object of type Connection. See the documentation on the subject. You can always write your own connection to handle your specific case or use one of the generic connections that write to a FIFO or a Socket and write the other side of the pipe.

Assuming you use the IsoTP protocol as a transport layer and you use my other project, you can use the PythonCanIsoTPConnection object. This object will bridge the UDS layer with the IsoTP layer. Your problem will be pushed down a layer below and you will need to find a way to bridge the IsoTP layer with your hardware. There, you'll have 2 options

1. Write 2 functions, one for reception (rxfn) and one for transmission (txfn) and give these functions to the IsoTP layer. You make the bridge between the transport layer and the link layer
2. Make usage of python-can that is a cross-platform CAN library that works under Windows with the most popular dongle out there . The bridge between IsoTP layer and python-can is already written, check for the CanStack object. If your device is supported by python-can, it should be a no brainer to setup.

Also, note that any implementation of the underlying layers (transport/link layer) executed in the user space won't be able to respect the timings dictated by ISO-15765. Only the Linux kernel module and some other vendor specific libraries can guarantee their respect.

Finally, take the time to read the documentation. Most of what I wrote is already written in there.
