 Posted: Tue Sep 08, 2009 11:06 am Post subject: I2M Minilap gps logger |
 |
|
hi,
i have the Minilap R I2M chrono, with also the additional DAE module, in this way i can record the gps data and other signals from the moto unit like RPM, throttle, rear wheel speed, and from this i can know the gear used.
i already make some video building a custom dashboard and configuring some simple data like gps position, gps speed, throttle position and RPM; you can watch it on this link: http://www.youtube.com/watch?v=T0U0AywW5RM
is it possibile having some more data from the gps coordinates, like decelleration slider?
i tried to use the pinto's program to interpolate data at 25hz, but using the interpolated data the throttle slider becomes "slower" and more linear, the gps speed, rpm and trackmap becomes really faster and smoother, i think there is a little problem with the calculating method for the other data, if you need i can post the log exported from danas.

in this case the REAR signal is the TPS data |

This sacrifies some accuracy, but it was the only way I could make it work. |
This is what I wrote in an earlier post about Pinto.
What I try to explain in the Readme.txt file is that the way the log file is structured, forced me to make Pinto interpolate the telemetry data at the same Hz as the GPS data.
That means a lot of telemetry is skipped and replaced by interpolated values in the Pinto output.
So, it's not an error, it's just the best I can do 
I don't have the programming skills to make it better right now.

hi uthaug,
yes, now i understood the meaning of the readme.txt...
so i'm tryng to find a solution using the raw data and not the exported csv format file... using the raw there are 2 streaming for each session, 1 for gps data, with a GPS$ prefix, and 1 for data acquisition with VALUE$ prefix...
i'm trying to make a software for interpolating the raw data using 2 kind of interpolation, 1 for gps and 1 for telemetry
now, the other question... is there a way to have brake signal from gps values? because i have no sensor for braking signal...  |

If there's is not already a brake value (Pandora generates it for example)
then you can calculate it from the speed value.
if "previous speed value" is higher than "current speed value" then "brake value" = 1
or something similar.
I did this in a small track visualization program I experimented with (that I never finished).
