  • How well do you know UDS protocol is the counter question of mine. – VioletVynil Nov 20 '18 at 14:55
  • i have a good knowledge about it , also trying to get ISO 14229-3 to be full understand that , i don't implemented it yet for sure . – ibrahim mostafa Nov 20 '18 at 16:04
  • What you really need is the ISO 15765-3 and ISO 15765-2. You need to know the TPConnection establishment, framing and buffering rules, half-duplex full duplex TP connection specs etc. If you know them, implementing a UDS through XL lib is like writing a letter. – VioletVynil Nov 20 '18 at 16:31
  • there is no 1765-3 2016 i think !! i have 1765-2 2016 , 1765-2 , 1765-3 2004 am i right ? – ibrahim mostafa Nov 21 '18 at 15:57
  • The 15765 -3 2004 will be fine. Not much was changed during these years anyway. – VioletVynil Nov 21 '18 at 16:09
  • sorry i don't make my question Clear , is 1765-2 2016 is enough ? – ibrahim mostafa Nov 21 '18 at 16:24
  • No, the 15765 -3 is more important for your usecase to know. 15765 - 2 is not that important, and having the version 2016 is good, but still not relevant. – VioletVynil Nov 23 '18 at 08:34

The whole stack of librairies exists in Python. Look at the UdsOnCAN package that will handle the application layer. You can use it with can-isotp and python-can for the underlying protocols. python-can support Vector hardware.

This example shows how to setup the three packages with a Vector interface.
