IMPORTANT THIS IS DEPRECATED

Instead, please use this driver: github.com/rnd-ash/macchina-J2534/

Which has support for both Macchina's M2 and A0 adapters

M2 under the dash passthru

Passthru API (j2534) Driver for Macchina M2 Under the dash

What works (35%)

  • Driver registration
  • Driver calling from userspace application
  • Logging
  • ISO15765

What doesn't work (65%)

  • ISO1941
  • CAN

Requirments

  • Works on Win7+ (x86 and x64) - Windows XP may work, but untested
  • Follow the guide here to get Arduino IDE setup to receive the arduino sketch
  • Install Visual studio with C++ support in order to build the DLL

Usage

  1. Run installer/install.bat
  2. Compile the driver module, copy the compiled dll to C:\Program Files (x86)\macchina\passthru\
  3. Open the macchina directory in arduino IDE and upload to M2 UTD
  4. IMPORTANT: Set the Macchina M2 as COM12 in device manager! (Currently its hard coded in the dll but i have plans to change that)
  5. Select "Macchina-Passthru" as your J2534 device

Logging

Log file is located at C:\Program Files (x86)\macchina\passthru\activity.log

It is suggested for now to use WSL to tail the log file to get live data
