[Ovmsdev] Volt/Ampera CAN Logs

[mikeljo at mac.com]

Hi,

yesterday i got some Logs.
I do one log for each action. Lock/unlock car, open/close door, Remote start, Plugin/remove Charging Plug, .....
I do the action in 5 second interval.
I think i found some IDs.
And i found something interesting: Some IDs cycle 4 with 4 times Blocks. That mean there is a counter or an adress field in one data field that repeats after 4 times. It counts like 10 20 30 40, FF FE FD FC, or...... the rest of the data fields change there value.
Can anybody confirm?
Didi anybody see this before?
I can see this after sort the Logs (Excel). As Sort field i use the ID. So i can see the value changing over time.

Bye
Michael

It seems that the number the Volt supplies is a 31-bit signed integer.  The easiest way to handle that, I think, would be to add "latlon = latlon<<  1;" before checking for<0, and then "latlon = latlon>>  1;" afterwards.  Running the code you have with those two changes seems to work fine.

If the GPS data is unobtainable, I believe the car reports the most recent reading.  The GPS data comes from the OnStar system, so I am thinking it may only provide the data if the OnStar service has been activated, which could be a problem for owners outside of U.S/Canada.
