variable scope in classes

Projects Programming
26

So again, here is the entire code, which works, though trimmed down from its original form (it currently just displays "boot complete and the contents of 2 variables for troubleshooting purposes)

It successfully calls on the LCDUPDATE class in the header and updates the screen once
The problem is that lcd.setCursor(3, 3); does not work, it just moves to the 3rd cell of the screen instead of the 3rd row, 3rd cell like it should
The same thing that happens if you don't have an lcd.begin stated in your sketch (but it is)

It appears that lcd.begin is not valid in the header, even removing it from the sketch and only stating it in the header doesn't work. (lcd does not name a type) even when liquidcrystal.h is included and the liquidcrystal variable is declared.

I've tried looking into the liquidcrystal library, thats way above my pay grade.

Main Sketch

//include required libraries
#include <SoftwareSerial.h>
#include <LiquidCrystal.h>
#include <Stepper.h>
#include "LCDU.h"
;





//===CONSTANTS and variables (buttons and pins)
const int buttonPin = 9;    // start button
const int estopbutton = 8;  //estop button
const int indexswitch = 7;  //table index switch
const int indexmotor = 6;   //table stepper motor
const int indexdir = 10;    //table stepper direction pin
//===== LED PINS
const int stn1good = 50;         //50
const int stn1bad = 52;          //52
const int stn2good = 46;         //46
const int stn2bad = 48;          //48
//===== STEPPER PINS
const int stepsPerRevolution = 200;
Stepper myStepper(stepsPerRevolution, 42, 40, 38, 36);
int stepspeed = 10;
//ALSO SEE myStepper.setSpeed(100);
//==== LCD Variable

int LCDtest = 0;
int printtest;
