Implementing RS485 on F28027

Bruno Duarte

Hi,
I'm new to this microcontroler programing and specialy to the communication part.

I need to implement a communication between a master and several slaves ( all F28027 ) for a project.
Since the microcontroler doesn't have CAN , i was thinking on using RS485.
Could anyone give me some tips and/or guidelines about how to do this ?
I've already began my research but it's always better if anyone who already had experience in this could help me starting.

Thanks

    Hi Bruno,

    This controller has a SCI port ie equivalent to USART/UART based communication ie RS232. For implementing RS485 you'll have to use a converter.

    Hi Gautam,

    Thanks for that help, i'll search for those converters.

    But in terms of the communication, i have to develop the code to control the information flow ( like to whom the master is sending and from who is receiving, etc ) or is there some kind protocol devoloped? The selection of the one who is sending and receiving is controled via hardware?

    Best Regards.
