Re: CAN/CANopen boot loader

Just post on mailing list you will get lot of help for getting started &
using already existing modules ..


>> - the Object Dictionary to control the boot loader
>> - the special access methods to the object dictionary,  especially the
CANopen SDO domain transfer
   Can you brief me what what really is done here ? Then i can tell you how
it can be related to VSCP bootloader.

If you are talking about this :--
http://en.wikipedia.org/wiki/CANopen#Object_dictionary

Then Can-Open is just small child in front of VSCP.
Because in VSCP you can have many pages of configuration registers for a
device. And each page can have internal 256 registers.
Also VSCP class-0, directly allow you to modify all these on field. Also
Device configuration registers can be stored in XML file format.
This allows easy diagnostics & configuration of device on field. Lot
more.... very powerfull & under-estimated opensource project.. VSCP.

And GUI supports all these work for you.

>> Do you have a direct link to the download GUI manual? (don't like to
download 572 MB).
Here is the specifications.
