AD7606 ADC Sensor Library for ESP8266 (ESP12E)

English | 繁體中文

Description
This library provides functions to communicate with an AD7606 ADC using an ESP8266 board (such as NodeMCU). It utilizes hardware SPI to read 8 channels of data from the AD7606, allowing you to easily retrieve voltage measurements.

Features

• Hardware SPI reading from AD7606
• Customizable SPI frequency, bit order, and mode
• Simple offset threshold (scaleFactor & errorConst)
• Helper function to print all 8 channel voltages at once

Installation

1. Download or clone this repository.
2. Place the folder AD7606-ADC-Sensor-Library-for-ESP8266 into the libraries folder of your Arduino installation.
3. Restart the Arduino IDE (or click Sketch > Include Library > Add .ZIP Library if you have a ZIP file).

Usage

1. In your sketch, add #include <AD7606_ESP8266.h>.
2. Create an AD7606_ESP8266 object.
3. Call setPins() if needed to specify custom pins (otherwise default pins are used).
4. Call setSPISettings() if you need different SPI parameters (default is 1MHz, MSBFIRST, SPI_MODE0).
5. Call begin() to initialize the device.
6. Use readData() and parseRawBytes() to read data, then retrieve voltage with getVoltage(channel), or use printAllVoltages() to print all channels.
