# TL,DR
|
||||
|
||||
With all the electromagnetic interference around the gasoline engine due to sparking CAN physical layer provides the level of reliability above RS232 and USB physical layers.
|
||||
|
||||
[ISO 15765-2](PDFs/ISO-15765-2-2004.pdf), or ISO-TP (Transport Layer), helps us exchange up to 4096 packets into which we wrap TS protocol. See also [wikipedia](https://en.wikipedia.org/wiki/ISO_15765-2)
|
||||
|
||||
https://github.com/rusefi/rusefi/tree/master/java_console/io/src/main/java/com/rusefi/io/can folder has java implementation of ISO-TP packet encoding/decoding.
|
||||
|
||||
There is no standard way of communicating with CAN bus on Windows. At the moment rusEFI is focusing on [PCAN by Peak System](https://www.peak-system.com/) and ELM327 options of the Windows side of CAN.

# PCAN
|
||||
Between three major professional CAN frontend vendors we like PCAN by https://www.peak-system.com/ due to the combination of the following
|
||||
1) documented Windows DLL drivers with official java wrappers called [PCAN-Basic API](https://www.peak-system.com/PCAN-Basic.239.0.html?&L=1)
|
||||
|
||||
2) https://github.com/moonglow/pcan_cantact open source firmware for [cheeeeeeap third party devices](https://rusefi.com/forum/viewtopic.php?f=13&t=2243 )
|
||||
|
||||
rusEFI bridge between PCAN and ISO-TP is located at https://github.com/rusefi/rusefi/tree/master/java_console/io/src/main/java/com/rusefi/io/stream
|
||||
|
||||
# ELM327
|
||||
|
||||
With more than a dozen magic commands it's possible to switch ELM327 device into binary transition with serial communication between calibration software and ELM327 acting as a bridge. At the moment we have a very odd bug making the overall solution not working as of Jan 2022.
|
||||
|
||||
|
||||
|
||||
See https://canhacker.com/ch-obd-m02/ for great pinout image. Yes both GND are needed for reliable ELM327 operation.
