Went there but there isn't much information. Not enough details to be useful. About all it says is "I'm in the final stage of the protocol specification and I plan to have the version 1.0 shortly." -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of Marco DI LEO Sent: Monday, August 02, 1999 5:51 AM To: PICLIST@MITVMA.MIT.EDU Subject: Re: RS485 with a little PIC'up Take a look at the Tiny Embedded Network. It is a peer to peer protocol that implements CSMA/CD for arbitration and uses RS485 for the physical layer. The protocol is simple enough to be implemented in a PIC and can take advantage from the presence of a UART. The main advantage of using a peer to peer network is that you can turn off your PC and still being able to switch on the light... TEN implements group and multicast addressing so you can have multiple systems (sprinklers, burglar alarm, audio distribution, etc.) on the same wiring. You can find more information on TEN at: http://members.tripod.com/~mdileo/ Ciao Marco
