obd-ii_uart's Issues

not working with SAE 1939

I don't know if this product gets activelly supported, I have been using this product with cars and truck, works just fine, but can not read from a SAE - 1939 truck.

Directly communicate with can bus?

The schematic says it uses the mcp2551 for can bus. Is there a way I can directly communicate with the can-bus without having to go through obd2 interface?

arduino library for the Keyword Protocol 2000

Hi!

I made a library to make the comunication and the development of software for the ECU easier
Keyword Protocol 2000
I think that the original tutorial has been created by toni_k but i don't know his github name
You may consider to add this to the tutorial
I also made a python script that emulates an ECU and it is very useful for the development, somehow similar to the ECUsim 2000 you pubblish only limited to the iso14230 but free
