Interfacing myRIO with HX711 Load Cell

[Pelabu]

24 bit ADC Module for Weight Scale

HX711

 OBJECTIVES

            The main purpose of this project is to read data from HX711 with NI myRIO. After the main purpose is reached, we will compare the output between myRIO and arduino.

HARDWARE OVERVIEW

1. HX711
2. myRIO
3. Load Cell 20kg

4. Arduino Uno
5. Virtual Bench

Connection Diagram

 SOFTWARE

1. Labview with FPGA module

This software is used to program myRIO. The code that is used is inside hx711 myrio.rar

2. Arduino IDE

This software is used to program arduino uno. The code that is used is inside HX711 Arduino Library.zip

MYRIO AND ARDUINO COMPARISON

Signal captured with Virtual Bench. The red signal is DT pin and the yellow one is SCK pin.

This is exactly what I needed thank you so much

hey, very nice. have you made this using DAQ ? because i should submit almost the same work but using labview and daq, and honestly im new to this and i've been looking for something useful and found your work. thnx in advance and nice work

Can you share video? How to interface myrio with load cell. I am stuck in VI diagram? Which type of VI circuit is required to make interface?

HI, Ty for the code. 

Im new to labview and im having a little bit of touble getting the code to run, im having this issuue, Could you help me?

[CZUJYJ]

Hello, I have practiced it on LabVIEW through the program provided by you, but the result after the program runs is as follows:

As shown in the figure, the values obtained are all - 1. I replaced the two digital signals in the original program with the functions provided by myrio. If you see this message, I hope you can help me see where the problem is. Thank you so much for your help and dedication。

Me too. I have the same problem. Please help me.
