2 load cell sensor with 2 HX711

Other Hardware Sensors
1

Newbie here. I need help, my 2 load cell sensors are currently can run individuall but when both sensors are being joined(integrated) together the serial output only displays 7 consecutive output and it stops.

NOTE: Currently using this library for HX771 GitHub - bogde/HX711: An Arduino library to interface the Avia Semiconductor HX711 24-Bit Analog-to-Digital Converter (ADC) for Weight Scales.

See the attached file for the OUTPUT(Output.png).

Here's my code:

#include "HX711.h"

 // parameter "gain" is ommited; the default value 128 is used by the library
 // HX711.DOUT  - pin #A1
 // HX711.PD_SCK - pin #A0
 
HX711 scale;
HX711 scale1;

long temp=0;
long temp1=0;
int Value=0;
int Value1=0;

void setup() {
  Serial.begin(38400);
  
  scale.begin(A1, A0);
  scale.set_scale(2280.f);     // this value is obtained by calibrating the scale with known weights; see the README for details
  scale.tare();

  scale1.begin(A3, A2); 
  scale1.set_scale(2280.f);
  scale1.tare(); 
  
}

void loop() {
 // put your main code here, to run repeatedly:     
 temp = scale.get_units(), 1;
 temp = temp*10;
 Value = (int)(temp);
 Serial.println(Value);
     
 temp1 = scale1.get_units(), 1;
 temp1 = temp1*10;
 Value1 = (int)(temp1);
 Serial.println(Value1);
}

Not standard usage:

temp=scale.get_units(), 1;

Does it even compile?

3

yes as what I've mentioned, it does have 7 outputs only.

4

Let me rephrase that.

That's wrong usage of get_units. You are mixing in serial print parameters

Go back to the bogde library and read up on how it is supposed to be called.

Good day sir daveEvans, im trying to monitor the raw output data. For my understanding, having the parameters will get the average value.

I don't see a question in your last post. Did you intend to ask one?

Are you aware that there's a nice little code reference on this site at Arduino - Home? Bookmark it and refer to it often. Especially please read up on Serial and its println function...notably println(val,format)...with attention to my post #3.

Also, do you understand the code and the comments in the following code from the bogde library?

  Serial.print("read: \t\t");
  Serial.println(scale.read());                 // print a ***raw*** reading from the ADC

  Serial.print("read average: \t\t");
  Serial.println(scale.read_average(20));       // print the average of 20 readings from the ADC

  Serial.print("get value: \t\t");
  Serial.println(scale.get_value(5)); // print the average of 5 readings from the ADC minus the tare weight, set with tare()

  Serial.print("get units: \t\t");
  Serial.println(scale.get_units(5), 1);        // ***print*** the average of 5 readings from the ADC minus tare weight, divided
 // by the SCALE parameter set with set_scale
