DDT4All Python App Donate Discord

DDT4All is tool to create your own ECU parameters screens and connect to a CAN network with a cheap ELM327 interface.

Android porting:

Notes:

This application is work in progress, so be very careful when using expert mode. Using the application in non expert mode should not be harmful for your vehicle (leave the expert mode button released).

Important :

Do not use this software if you don't have a strong knowledge of how a CAN network (or ECU) works, you can really do bad things with it, especially if you're working on a vehicle

The author declines all responsibility about a bad use of this tool. You are the only responsible

This tool is mainly aimed for CAN ISO_TP network study

Cloning Source Code

Dependencies :

Supported diagnostic adapters (so far)

  • ELM327 USB/BlueTooth/WiFi (Original one with PIC18F25K80, Chinese clone not working)

Next, you need to get the source code. This source code repository uses git submodules. So when you clone the source code, you will need to clone recursively:

git clone --recursive https://github.com/cedricp/ddt4all.git

Or if you already cloned without the recursive option, you can update the submodules by running:

git clone --recursive https://github.com/cedricp/ddt4all.git
cd ddt4all
git submodule update --init --recursive
