Cant declare class of Adafruit_ILI9341

krakert · September 30, 2021, 12:59pm

I want to make a wraper class to controll a 2.4 Inch TFT display using the Adafruit_ILI9341 and XPT2046 libary's. So I wanted to make a class displayHandler that i can use in my main.cpp but it is giving me a bit of a hard time.

In the displayHandler.h I declared Adafruit_ILI9341 tft; and XPT2046_Touchscreen ts; I made them private, and only want to share them in the displayHandler.cpp file. So i can use tft. in other funtions.

it has something to do with Adafruit_ILI9341 tft;

displayHandler.h

#ifndef DISPLAYHANDLER_H
#define DISPLAYHANDLER_H

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_ILI9341.h>
#include <XPT2046_Touchscreen.h>

/* PARAMETERS STANDARD TFT AND TS*/ 
#define TFT_CS              D0 
#define TFT_DC              D8  
#define TS_CS               D3 
#define TFT_RST             -1

#define DISPLAY_ROTATION    3
#define TOUCH_ROTATION      1

class displayHandler {
    public:
        displayHandler(uint8_t tftCs = TFT_CS, 
                       uint8_t tftDc = TFT_DC, 
                       uint8_t tftRst = TFT_RST, 
                       uint8_t tsCs = TS_CS,
                       uint8_t displayRotation = DISPLAY_ROTATION,
                       uint8_t touchRotation = TOUCH_ROTATION);
        void showInitScreen();
    private:    
        Adafruit_ILI9341 tft;
        XPT2046_Touchscreen ts;
};

#endif // DISPLAYHANDLER_H

displayHadler.cpp

#include <displayHandler.h>

displayHandler::displayHandler(uint8_t tftCs, uint8_t tftDc, uint8_t tftRst, uint8_t tsCs, uint8_t displayRotation, uint8_t touchRotation){
    tft = Adafruit_ILI9341(tftCs, tftDc, tftRst);
    XPT2046_Touchscreen ts(TS_CS);
    ts.begin();
    ts.setRotation(touchRotation);
    tft.begin();
    tft.setRotation(displayRotation);
}

Exactly what would "it" be? Posting PICTURES of error messages is useless. Copy and post the complete error messages. Post them in Code Tags just like you did with your program's code.

Did you read the reference I provided?

It looks like classes Adafruit_ILI9341 and XPT2046_Touchscreen don't have a constructor that takes "0 arguments".

To have those objects inside your class you have to construct them at the same time your class is constructed. To do that, you pass the required constructor arguments like this:

displayHandler::displayHandler(uint8_t tftCs, uint8_t tftDc, uint8_t tftRst, uint8_t tsCs, uint8_t displayRotation, uint8_t touchRotation)
   : 
    tft(tftCs, tftDc, tftRst),  // Construct 'tft' object
    ts(TS_CS) // Construct 'ts' object
{
