TFT HX711 scale readings,cannot perform sprites

[Kalougear]

Hello guys!

Im trying to implement sprites on my project to avoid flickering of the screen on my measurements,i tried my best but this does not go anywhere.im getting readings without sprite implementation correctly but i have a flickering that i want to avoid,i tried to incorporate on my code some sprite code as good as i could from the examples but im Getting no readings,just a plain blue background,Im using Esp32 with TFT_e_SPI library and im proggraming with platformio,im using tabs so i can i have my project organized well through the proccess thats why its a little bit strange,any way here is my code.

main.cpp

#include <HX711_ADC.h>
#include <TFT_eSPI.h>
#include <displayScaleReading.h>
#include <EEPROM.h>

    Serial.begin(9600);

    LoadCell.begin();
    float calibrationValue = 696.0;       // Set the calibration value (see example file "Calibration.ino")
    unsigned long stabilizingTime = 2000; // Precision right after power-up can be improved by adding a few seconds of stabilizing time
#if defined(ESP8266) || defined(ESP32)
    EEPROM.begin(512); // uncomment this if you use ESP8266/ESP32 and want to fetch the calibration value from eeprom
#endif
    EEPROM.get(calVal_eepromAdress, calibrationValue); // uncomment this if you want to fetch the calibration value from eeprom

    LoadCell.start(stabilizingTime, false); // Avoid taring
    if (LoadCell.getTareTimeoutFlag())
    {
        while (1)
            ;
    }
    else
    {
        LoadCell.setCalFactor(calibrationValue);
    }

You don't have enough RAM to drive a 320x240 sprite.....

Cut it down to 200x200 or less and see what happens....

Thank you for your response,I use an esp32 I thought it was enough! I'm going to try it!

I now make my sprites only big enough to contain what I'm trying to display. Smaller sprites save ram....
