RS-485 Arduino Communication: Simplex, Half-Duplex & Full-Duplex with MAX485
𝗩𝗶𝗱𝗲𝗼 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻
This tutorial is about RS-485 communication using the MAX485 Module from Maxim Integrated. If you've worked with microcontrollers before, you might know that protocols like UART, I2C, and SPI are great for short distances. But when you start extending those wires, problems can crop up—like lost or corrupted data. That's where RS-485 comes in, letting you communicate over distances as long as 1200 meters without a hitch.
In this video, we’re focusing on the MAX485 IC, a sturdy little device that’s built to handle RS-485 communication even in places with a lot of electrical noise. We’ll explore how to set up your Arduino to communicate using simplex, half-duplex, and full-duplex modes. The MAX485 is perfect RS-485 Module as it operates on 5V, can handle data speeds up to 2.5 Mbps, and allows up to 32 devices on the same communication line.
We’ll walk you through everything from the basics to more complex setups, showing you how to manage sending and receiving data with ease. Whether you’re setting up a network of devices or just experimenting with new ways to communicate, this tutorial has got you covered.
