Step by step

Hardware

You can see a complete energy node circuit of this [Smart home energy monitoring & management system](https://www.instructables.com/id/Smart-home-energy-management-system-SHEMMS/)

Instance the class

Here you will learn how to correctly make a cs5490 instance for you board

1. Arduino UNO and ESP8622 Custom Arduino Boards uses software serial, so you need to define TX and RX pins.

CS5490 line(MCLK,rx,tx);

2. ESP 32 and Arduino MEGA It uses by Serial2 default.

CS5490 line(MCLK);

Begin communication

At setup code, you need to begin serial communication.

line.begin(baudRate);

Reading and Writing

See Methods page and choose a register to read or write
You can read any register with

line.readReg(page, address);

You can write any register with

line.write(page, address, value)
