sample rs485 protocol - Rickey's World of Microcontrollers & Microprocessors

Forum -> General help Guidance and Discussion

if you know how to communicate over uart/RS232 of 8051. then it becomes easy for you to work on RS485. As Majoka mentioned, RS485 is nothing but uart + voltage level of RS485 standard. So on protocol level they work over uart but on physical media they are on RS485 which is a multidrop bus communication.

You can design a packet for communication and each 8051 over that bus will have an ID. so you c... Read Compelte post
