Software J2534 Device Emulation Project

Post by jakka »

Hello,

I've just finished up making a little tool that is a complete solution for J2534 Device Emulation in Software, that works without having to have any device plugged in, and behaves as if the device is actually in a vehicle exchanging messages with an ECU. Full emulation of the whole system via ISO14229 and the SAE J2534 spec, pretty chubbed with it, have just posted a release on the github, and about to upload the code. Full open sauce, so enjoy. :punk:

Thanks for the hard work, first issue is it doesn't appear to be able to handle raw CAN???
Can you select ECM and calibration responses, or responses for anything, I know you generally work with ford and I work with gm so I was curious how compatible it would be..

Currently only ISO15765, If people start dropping all the protocols they wanna use I can start implementing them. I've just added SAE1979/OBD2, and completely creating a full ISO14229 is next. Could probably create a nice little GUi that has all the various options built in to select the various protocols as people would want to use them.
