Lpc2000

CAN bus was thought of but as we needed to interface with an onther
RS-485 system it was put in the drawer again.

I do am tempted to switch to it as the main bus and in case of old
system have a RS-485 doughter card the adopt to them.

Will certenly put some time on CAN after this new card is done and
maybe change later next year if possible.

I'll have a look on the VSCP project also...

All products will be on a web site about february next year.

Cheers
/Johan
