An Arduino library to interface the Avia Semiconductor HX711 24-Bit Analog-to-Digital Converter (ADC) for reading load cells / weight scales.. The Hx711 uses SPI interface to communiacate to the Arduino. Which library are you using for the HX711? Library for the HX711 24-bit ADC for weight scales. Library to interface the Avia Semiconductor HX711 ADC. Tare function can also be performed without halting the mcu. Examples also includes calibration procedure and interrupt drive. Non-blocking, smoothed data from "Moving average" rolling data set. HX711 Arduino Library. Arduino Robot Library. To download the library, go to the Library Manager in the Arduino IDE and type HX711. For this tutorial, I will be using a lightweight HX711 load cell library by Queuetue named “”. The Arduino programming language Reference, organized into Functions, Variable and Constant, and Structure keywords. Introduction. // HX711_ADC.h // Arduino master library for HX711 24-Bit Analog-to-Digital Converter for Weigh Scales // Olav Kallhovd sept2017 // Tested with : HX711 asian module on channel A and YZC-133 3kg load cell // Tested with MCU : Arduino Nano, ESP8266 //----- It supports the architectures atmelavr, espressif8266, espressif32, atmelsam, teensy and ststm32 by corresponding PlatformIO targets.. Synopsis Blocking mode. This an Arduino library for the HX711 24-bit ADC for weight scales. EEPROM is the inbuilt library of Arduino ide, which is used to store values in EEPROM and the LiquidCrystal library is for the l2C LCD Module. The first hit I get on google for HX711.h, for bogde/HX711, would declare the scale as follows, but the exact method is going to depend on which library … Esplora - this library enable you to easily access to various sensors and actuators mounted on the Esplora board. Also the ADC on the arduino is 10 bit which provides a maximum of 2^10 ie. Have you looked at any of the examples for the HX711 to see how the scale is declared in those? Connection is pretty simple. Bridge Library - Enables communication between the Linux processor and the microcontroller on the Yún. 1. Overview: In this project we will be “interfacing HX711 Load cell amplifier with Arduino” and 16*2 LCD for designing Weighing Machine using Arduino Load Cell & HX711 Module. Yún devices Library. This Hookup Guide will show you how to get started with this amplifier using some of the various load cells we carry at SparkFun. Library to interface the Avia Semiconductor HX711 ADC. Author: Olav Kallhovd. The library is usually used in blocking mode, i.e. Robot - this library enables easy access to the functions of the Arduino Robot. I downloaded and installed the library from the link there, it is installed in folder /libraries/Hx711 that contains files Hx711.cpp, Hx711.h, and a samples folder with folders named LiquidCrystalScale and Serial Scale containing files LiquidCrystalScale.ino and SerialScale.ino files. Support for doing conversions on multiple HX711 modules simultaniously. The electronic weighing machine uses a load cell to measure the weight produced by the load, here most load cells are following the method of a strain … This is a simple “Arduino Weight Measurement project”.. Read the documentation Connecting to Arduino . Data retrieval from the HX711 is done without halting the mcu, also on the 10SPS rate setting and with Multiple HX711's performing conversions simultaneously. The use of this library was found to be the easiest and most stable to implement in terms of performance. 1024 readings compared to HX711 which is 24 bit ADC and easy to interface. HX711 Datasheet. (Refer Data sheet for more info) More info on DfRobots. Sensors. HX711_ADC. #include #include #include Then defined integers for different pins and assigned values. HX711_ADC loadcell function is for setting the Dout and clock pin. The HX711 load cell amplifier is used to get measurable data out from a load cell and strain gauge. Maintainer: Olav Kallhovd.
