Dear Friends i am doing my university project the details of which are as follow
i need to develop a system for communication between six clients and one server i.e i have to establish a channel for communication of 6 micro-controllers to a single PC.
And the communication in between must be RS485. I need to develop a working hardware and software. As per hardware portion i have successfully developed RS232 to RS485 converter from a web link (www.circuit-projects.com).
Attached is the image how i have connected my system the problem i am facing is that when i send a data from any of the 6 micro-controllers or from PC it is read by all other connected. i want to establish a system so that if i send a data from PC to say micro-controller # 01 so the data must be read only by micro-controller # 01.
You can say i want to implement some sort of bus topology can anyone guide me in this task.
Thanks in anticipation.
