RS-485 – The Details (1/4): Timeouts, Addressing, Multiple Slaves

With demonstrations using Arduinos and TI SN75176B transceivers … ↓↓↓ Complete description, time index and links below ↓↓↓ In the previous video we developed protocol, hardware and software for two Arduinos, a master and a slave, to communicate via RS-485 (link below). Now it’s time to handle unresponsive slaves and more than one slave. First we talk about the necessity of timeouts to protect our master from unresponsive slaves and extend our master’s code accordingly. Then we add addressing to the whole scheme, which allows us to have multiple slaves on the bus. 00:00 Intro – fixing a fatal flaw and controlling multiple slaves 00:59 Timeouts – necessary evil of RS-485 master-slave busses 11:32 Addressing – required if you want more than one slave 24:09 Wrap-up – next is biasing the bus to simplifying things, bye Tutorials    • Tutorials   RS-485 – The Basics (1/2): Principles, Topology, Specification, Performance    • RS-485 – The Basics (1/2): Principles...   RS-485 – The Basics (2/2): Simple Master-Slave Half-Duplex Setup    • RS-485 – The Basics (2/2): Simple Mas...   RS-485 – The Details (1/4): Timeouts, Addressing, Multiple Slaves    • RS-485 – The Details (1/4): Timeouts,...   RS-485 – The Details (2/4): Failsafe Biasing, Associated Protocol Simplifications    • RS-485 – The Details (2/4): Failsafe ...   RS-485 – The Details (3/4): Full-Duplex Bus, Interleaving Messages    • RS-485 – The Details (3/4): Full-Dupl...   RS-485 – The Details (4/4): Modbus, PROFIBUS, DMX    • RS-485 – The Details (4/4): Modbus, P...   RS-422 Differential Signaling (Renesas ISL8490, Arduino MCU) – The Basics (1/2)    • RS-422 Differential Signaling (Renesa...   RS-422 Differential Signaling (Renesas ISL8490, Arduino MCU) – The Basics (2/2)    • RS-422 Differential Signaling (Renesa...   RS-422 Differential Signaling (ISL8490, AdUM121N) – The Details (1/2)    • RS-422 Differential Signaling (ISL849...   RS-422 Differential Signaling (ISL8490, AdUM121N) – The Details (2/3)    • RS-422 Differential Signaling (ISL849...   RS-422 Differential Signaling (ISL8490, AdUM121N) – The Details (3/4)    • RS-422 Differential Signaling (ISL849...   RS-422 Differential Signaling (ISL8490, AdUM121N) – The Details (4/4)    • RS-422 Differential Signaling (ISL849...   My Code https://drive.google.com/drive/folder...
