Hi, I have built timer/controllers for 10 kodak dias caroussels with a pic18f2550 microcontroller, and I want them to communicate to each other. Therefore I put a IR-LED and a IR-receiver on the pic's serial port and want to build some kind of ir protocol to broadcast settings over the network. All caroussels can not "see" all the other ones, so each caroussel has to retransmit received packages.
For now I have build my own protocol based on MACAW, but it would be nice to use some kind of standard protocol. Do you have any suggestions for implementing a IR-based point-to-multipoint protocol for this project?
I know about I2C, CAN, etc, but they are all point-to-point and what abaout collision/media access? How should that be implemented with IR?
