I2c question

Hello everyone,

I'm doing a project i found on instructables(about a counting scale) and I'm facing a bit of a problem. The problem is that the guy on the project is using HX711 and LCD with I2c interface and i dont have the interface. I've connected my LCD and changed the original code so it could work. It shows the text but its not exactly what it should be. I'll be glad if someone lend me a hand or point me into the right direction. Thank you!

Here is the project: https://www.instructables.com/id/Counting-Scale-Made-With-an-Arduino/
Here is the original code: #include <Q2HX711.h>#include <LiquidCrystal_I2C.h>const int resolution=100 - Pastebin.com
Here is the changes i made on the code: #include "HX711.h" //library of scale//library of rfid#include <LiquidCrysta - Pastebin.com

P.S: I'm using Arduino Uno

Hi,

What LCD are you using?

Can you explain what the LCD is showing? Does "not exactly what it should be" mean the font size is too big or small? The letter is lower case instead of upper case? A few more details would be handy.

Hello again,

I'm using 16x2 LCD common one without I2c interface. I've managed to connect it and its working properly. I reviewed my code and found that there is a problem with the interupt buttons and thats why I'm getting on the lcd screen Count... and Tare... constantly and not itemweight. I guess i have my buttons connected wrong to my uno, so im trying to fix that. I'll update if i can manage to resolve the problem.

Thank you for your time.
