Load cell and potentiometer with the joystick library, need help!

Hi all,

I'm new to the forum and need some help with my DIY Load cell and potentiometer pedals project.

I'm building sim racing pedals set (throttle and break ), similar to the picture.

I am using an Arduino Pro Micro and was able to connect first pedal (break) via hx711 to PC.

Here the code I am found but I get this error 'no matching function for call to 'HX711::HX711(int, int)'. Can anybody help?

#include <HX711.h>
#include <Joystick.h>

  HX711 scale(0, 1);

  Joystick_ Joystick;

  
void setup() {

  pinMode(4, INPUT_PULLUP);      // Button Pins set to input with pull up risistors
  pinMode(5, INPUT_PULLUP);
  pinMode(6, INPUT_PULLUP);
  pinMode(7, INPUT_PULLUP);
  pinMode(8, INPUT_PULLUP);
  pinMode(9, INPUT_PULLUP);
  pinMode(10, INPUT_PULLUP);
  pinMode(16, INPUT_PULLUP);
  pinMode(14, INPUT_PULLUP);
  pinMode(15, INPUT_PULLUP);
  pinMode(18, INPUT_PULLUP);
  pinMode(19, INPUT_PULLUP);    
  
  pinMode(A2, INPUT);           // set potentiometer pins to input
  pinMode(A3, INPUT);            

  scale.set_scale(-10000);
  Joystick.begin(); 
}
 
  
void loop() {

Joystick.setButton(0, !digitalRead(4));       // turn on button if pin is connected to ground
Joystick.setButton(1, !digitalRead(5));
Joystick.setButton(2, !digitalRead(6));
Joystick.setButton(3, !digitalRead(7));
Joystick.setButton(4, !digitalRead(8));
Joystick.setButton(5, !digitalRead(9));
Joystick.setButton(6, !digitalRead(10));
Joystick.setButton(7, !digitalRead(16));
Joystick.setButton(8, !digitalRead(14));
Joystick.setButton(9, !digitalRead(15));
Joystick.setButton(10, !digitalRead(18));
Joystick.setButton(11, !digitalRead(19));

Joystick.setXAxis(analogRead(A2));              // analog read potentiometer 1 set x axis

Joystick.setYAxis(analogRead(A3));              // analog read potentiometer 1 set y axis

Joystick.setZAxis(abs(scale.get_units(1)));     // read load cell set z axis

Do not see any photo although I doubt it would help.
Best to include a circuit diagram including all connections and power supply (not fritzing) and your code in code brackets.

I upload the a pic and code.

Have You installed the HX711 library using the library handler?

5

yes

Use HX711 scale;

When you post your code, please use code tags <CODE>

type or paste code here

See the HX711_basic_example.ino in the examples folder.

That code looks like:

and seems broken w.r.t the common HX711 and Joystick libraries.

Maybe try the examples from whatever HX711 and Joystick libraries you have installed and adjust the code to match them
