Re: Electronic Wizards

[Pete Shew <pslists@xxxxxxxxx>]

My central heating controller system - now in phase 1 SWMBO acceptance
- uses an LCD display with a PIC 18F458 and CAN interface back to the
controller. I also have a CAN<->RS232 board connected to a PC. I use
two
pairs of CAT5 for connection, 12v power and CAN data.

The reason for CAN was that it is much cheaper than Ethernet, and
although much slower was easily adequate for the traffic I need with one
second updates of status and temperatures. The PIC has CAN hardware
built in and free driver software, and the CAN driver chips are a couple
of quid. At the moment I have around a 30m run of CAN bus wiring.

The trick is getting a pretty looking enclosure ..
