Multi interface USB module

Postby mobyfab » Tue Aug 05, 2014 12:04 pm

Hi there,

I'm working on a "smart" cable to connect to some motorcycle ECUs.
The cable supports a range of interface such as K-line, serial or CAN bus.

The hardware is a custom board using an STM32F303.

Not very useful for most people here, but there are some interesting parts:
- Analyses knock using the DSP library
- Integrated USB bootloader
- USB composite interface with serial and bulk
- Uses some of the extra drivers I worked on such as DAC.
- CPU usage monitoring

There is also a Qt GUI that I use to communicate with it, using my Qt USB library.

The project is here:
https://github.com/fpoussin/MotoLink

Still a work in progress.

Runs on 2.6.5, unmodified.

Lots of evolutions since the first version.
PCB is not very different, software has been updated, it runs on RT 3.1.x

Hi,

Very interesting, is it just a product or you are planning a product out of this?

Would is also be useful for cars? my mechanic always tells me that instrumentation is not cheap, especially updates.

It's just a hobby so far, but I'll probably build a few if there's interest, it will always be open source ;)

That would work for cars (anything actually) as well indeed.
As long as you have the software to edit your fuel maps it can be useful.
