Hello, Maybe this is not a question for this forum, but I still give it a try: I would like to have different 8051's (or derivatives) "talking to each other" via a serial protocol. One uC would be a 'master'. The other ones should trigger the master when some info (decoded RC5-signal) is available. Since the different devices will be put quite far from each other (several meters, up to maybe 25 meters each), I think the RS232 protocol is not suitable anymore for this (distance too long). Therefore, I was thinking to use RS485, but I have to be honest: I don't know a lot of this protocol/standard. Can someone tell me where to find useful information about this protocol? Eventually sites where some C source code for the protocol is already available to give it a start? Does Keil have some useful example programs next to the tig amounts of other examples already available? I didn't find anything regarding RS485 myself on the site, but there might be some 'hidden places' with more useful information... Any help would be highly appreciated. Rgds, --Geert
Hello guys, Thanks a lot for all your input. I think I have enough stuff to read and study. I'll try to go through the documents/components mentioned before and then I'll see how far my knowledge is about how to use RS-485. Thanks a lot! --Geert
