error: 'tft' was not declared in this scope

[2ant]

Hello,

I'm having trouble tring to order my code from spaghetti to nice .cpp and .h files.

I thought that puting :

#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();

At the start before the setup made so tft was global and accessible from anywhere.

I have a Functions.cpp file with :

#include <TFT_eSPI.h>
#include "Functions.h"

void ActionMessage::UpdateMessage(int BoxNum){
  tft.fillRect(100, 75, 100, 20, TFT_CYAN);
  tft.setCursor(100,75);
  tft.print(BoxNum);
};

I got this error : \Functions.cpp:8:3: error: 'tft' was not declared in this scope

I don't know what to do.

You have missing public declaration of tft - just put in Functions.cpp after all include this

extern TFT_eSPI tft;
