[Ovmsdev] Twizy SEVCON object dictionary

[Michael Balzer]

Hi Julien,

there's no publically available DCF or master 
dictionary covering the Twizy specific Gen4 
firmware, but I found out most of the registers 
are the same as for the latest common Gen4 firmware.

Use the master dictionary excel sheet (!) 
contained in the DVT software package. Google 
"sevcon dvt download" to find the download for that.

I downloaded the DCF from my Gen4 using the 
CANopen standard function, merged that with the 
master dictionary for the SDO documentation and 
added the few specific differences (overspeed 
warning thresholds for example). Sadly I cannot 
share the full result, as the master dictionary is 
copyrighted by SEVCON.

As an alternative I created the file 
"Twizy-SDO-List.ods" only containing the SDOs used 
by me and only containing my comments, so you can 
just merge this info into the master dictionary or 
use both side by side.

If you've got questions regarding specific SDOs 
don't hesitate to contact me. Up to now I seem to 
have been the only one experimenting on this 
level, would be nice to add another view.

Regards,
Michael
