Open Source OBDII scanner

**Trampas** · 12-09-2006, 03:35 PM

I have just updated my open source AVR based OBDII scanner to have a bootloader. This allows users to update the firmware very easy through the USB connection. Note that Microchip(PIC) version already has a firmware update feature.

I will be adding support for PWM and other protocols here in the next few weeks. I will also work on updating the website to include more documentation about protocols.

I love your device. Never noticed anything change in the repository though. What's going on?

Unfortunately, the hardware is too expensive for what the device does. You can buy a commercial off-the-shelf scanner that has more features, for less than it would cost you to build the Stern Tech.

That's the thing. I built myself two of them but since the other protocols never got implimented, I never had a chance to use it with my car.

The hardware is expensive (if you buy from him, build it into your own project and it's cheap), but the code is what's awesome about it. Just a shame it was never completed.
