R2-Net library for Arduino Boards

In this section of the web I am going to tell you how to use the R2-Net library so that you can implement it in your projects and command R2-Net devices from your hardware application. For this example I have used an Arduino Mega and an RS-485 transceiver through which we will communicate the R2-Net protocol. The Arduino Mega will send telegrams to the connected devices in the protocol format. The wiring diagram is as follows: HOW TO USE IT In each of the examples below are the codes to act on the devices. The following are available: Holo-Projectors (up […]

R2-Net Protocol

What is R2-Net? R2-Net is a serial communication protocol that circulates on a two-wire RS485 bus. The RS485 bus is an industrial bus widely used in industrial and professional systems, such as DMX, in photovoltaic systems, home automation … etc. What you intend With this system it is intended to unite all the circuits that are in the units (not only R2 and its variants, it is also possible to extrapolate it to other models) so that each one, according to his need, can add his own circuit, accessory or modification … without dying in the attempt. What can be […]
