Hi Andreas Could you please help me with the proper cct. for a PIC communicating over the supply line. I would like to use the CAN protocol, which according to your mail you are using. thank you, Lindo Mbatha Andreas Nyholm wrote: > For myself, I'm working towards a wired system using CAN > to communicate between PIC based modules in each room of the > house.

I think that would be a good solution for the future, easy to connect other devices to the same server. The biggest problem I found so far is the price, the solutions I found is about $15-20. Or does anyone have an idea how to build a microcontroller that communicates over IP for less than $10? /Andreas -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu --------------------------------- Do you Yahoo!?
