Hi,

I just got around to look into my traces of a run with "HD" off. I can see the "$PDSNS" traces, but still no luck with any output that looks like OBD2 (No "$PDOBD," in the trace).

I can see the "miniobd2d" process in the task list, so I'm pretty sure that the standalone programm is launched (as opposed to the harley parser built-in in minigpsd)

If I run miniobd2d from the command line, I get

Code:

Presss CTRL-C for hangup

I still have to strace that process to see what's going on.

Thanks, I just installed it and will take it for a spin tomorrow.

By the way, could you please put obd2dash.py into the installation image too? I guess that you always need the "correct" version for the "struct.unpack()" calls.

Using the currently distributed obd2dash.py gives me

Code:

/media/mmc1/minigpsd $ python obd2dash.py

Traceback (most recent call last):

  File "obd2dash.py", line 373, in <module>

    DashBoard()

  File "obd2dash.py", lini 47, in __init__

    self.gpsdata = mmap.mmap(self.gpsfile.fileno(), 300)

ValueError: mmap length is greater than the file size

Re: minigpsd/miniobd2d 0.31

oops. I will have time since I'm off work until monday and will be able to sync up 0.31 for a pre-release version.

Re: minigpsd/miniobd2d 0.31

0.31e is out on zdez, will be in extras-devel shortly

Fixed lots of problems and OBD is logged:

$PDOBD,41,0C,0B,54*58
Where can I find docs on how to translate that into usable data?

Re: minigpsd/miniobd2d 0.31

http://en.wikipedia.org/wiki/OBD-II_PIDs

Among others. Data is in hexadecimal (base 16).

41 is a response.
0C is the PID.
0B54 is the RPM*4

The accompanying program in python that does the dashboard contains the equations to do conversions.

Someone PM'ed me but has the account set to NOT receive private messages, which include replys.

I also just got a sparkfun 6dof accelerometer gyro combination.
http://www.sparkfun.com/commerce/pro...oducts_id=8190
(I got the 75 deg/sec - better precision for vehicles, but perhaps not for other applications, the 150 or 300 might be better). It will be integrated into minigpsd when I have some free time.

Re: minigpsd/miniobd2d 0.31

it was me :) i PM-ed you before my account got blocked for MP-s :)

did you receive my pm? :)

Re: minigpsd/miniobd2d 0.31

I got the PM but I couldn't reply. In short, you might need to configure it first (upon install it should work). It would be simple to write just the minimal information in CSV (and optionally zip that). Starting things up from boot is also fairly simple.

If you can't PM, just ask here.
