Pushbutton to toggle between units (ounces and grams) with HX711 and LCD screen

I can absolutely share the code!

It doesn't take live readings (readings every second) but it does take readings upon pressing the "Units Button"

#include "HX711.h"

#include "KTS_Button.h"

#define DOUT  8
#define CLK  7

#define unitsPin 6 //Units button at pin 6

#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
int tarePin = 9;  //Tare button at pin 9
float tareVal = 0;
float i = 0;

HX711 scale;

float calibration_factor = 360; //calibration factor for 5kg amazon load cell with gain 128 and grams as units

KTS_Button tareButton(tarePin);
KTS_Button unitsButton(unitsPin);

enum Unit {
  grams = 0,
  ounces,
  NUM_UNITS
}; Unit currentUnit = grams;

void cycleUnits() {
  currentUnit = currentUnit + 1;
  if (currentUnit == NUM_UNITS)
    currentUnit = 0;
}

void setup() {
  pinMode(SCK, OUTPUT);
  pinMode(tarePin, INPUT_PULLUP);
  lcd.begin(16, 2);
  scale.begin(DOUT, CLK, 128); //Start communications to HX711 pins and set gain factor 64|128 are options on Channel A
  scale.set_scale(calibration_factor);           //Required during scale startup, scale factor will be adjusted in main loop for calibration
  scale.tare();                //Reset the scale to 0
}

void loop() {
  if (tareButton.read() == SINGLE_PRESS) {
    scale.tare();
  }
 
  if (unitsButton.read() == SINGLE_PRESS) {
    cycleUnits();
    lcd.clear();
    lcd.print("Weight: ");
    delay(1000);
  

    switch (currentUnit) {
      case grams:
        lcd.print(scale.get_units (4), 1);
        lcd.print("g");
        break;
      case ounces:
        lcd.print(scale.get_units (4) * 0.03524, 1);
        lcd.print("oz");
        break;
    }
    }    }
