OBD-I Dash Logger Project

Has to be on the Android backwards so when you set it on dashboard it reflects onto windshield!

Already part of the app. ;)

I'll send him a message and see if he wants any details released yet.

so far i have 3 developers (which is as many as i want)

i'll do a 'display module' which is total knockoff of datamaster in gtk eventually, and hopefully this will be useable as a decent OBD-I datalogger for xwindows

an android one sounds awesome too, guess it'll just use a bluetooth SPP or something

i guess what it comes down to for me, is reeeeally just want to use this raspberry pi for something, unfortunately there are no stable android builds for it, and im way too lazy to dig into that kind of project

[steveo]

for some reason i was completely ignoring the fact that the pi has a fully functional gpio header

if i can make this thing read aldl data fairly reliably, and i build an output module with some basic scripting language built in, this little thing could function as a piggyback ECM to do practically anything, whether you decide to attach a screen to it or not.

could easily do things like:

- control a waste gate (turns it straight into a boost controller)
- get direct sensor inputs if for some reason the aldl isn't fast enough for a particular function (such as the above)
- 3d table of map/rpm/speed to automatically pop open an exhaust cutout
- shift lights, blinky lights, automatic james bond smoke screen, whatever

i guess at this point, scope creep will kill it, or it'll be really awesome.

just an update, despite my rusty c skills, i've managed to make this thing maintain ALDL comms and get packet data, with checksum verification and everything, although at the moment it just spits out raw packets in hex; that's a big step.

now to turn it into something good

Hey man, nice project. I know how much work it is to create something like this. I did sort of related but for MegaSquirt. It was bluetooth and had a battery so totally wireless. The code is here: http://github.com/sebgiroux/MegaCluster. Feel free to steal whatever you want. It's nothing really amazing but you might be able to reuse some of the widgets to do a basic display. Here is a video of it:


You probably have seen my GM ODB I project on this forum, but this is for Android, and unfortunately not open source.

Here's my ALDL dash board!

looks cool, i might just do that, i suck with the gui end of things
