Here is 2 videos: here i placed oled.clear(); and load it to arduino 13 апреля 2023 г. - YouTube
Here is i writed fast test display 13 апреля 2023 г. - YouTube
Here is display test code:

#include <SSD1306Ascii.h>
#include <SSD1306AsciiAvrI2c.h>
#include <EEPROM.h>
#include <avr/sleep.h>

#define pinX A2      // ось X джойстика
#define pinY A0      // ось Y джойстика
#define pinXT A6
#define pinYT A5
#define I2C_ADDRESS 0x3C
#define RST_PIN -1
String a = "this is a display test";
String b = "All this text is string";
String c = "aboba";
String d = "aboobaaboobaaboobaaboobaaboobaabooba";
String e = "pon";
SSD1306AsciiAvrI2c oled;
void setup() {
  Serial.begin(9600);
  pinMode(pinX, INPUT);
  pinMode(pinY, INPUT);
  #if RST_PIN >= 0
  oled.begin(&Adafruit128x64, I2C_ADDRESS, RST_PIN);
#else   // RST_PIN >= 0
  oled.begin(&Adafruit128x64, I2C_ADDRESS);
#endif  // RST_PIN >= 0 
        // Call oled.setI2cClock(frequency) to change from the default frequency.
  oled.setFont(Adafruit5x7);
  oled.println("Hello Sahsa!");
  delay(3000);
  oled.clear();
}
void loop()
{
  oled.clear();
  oled.println(a);
  delay(1000);
  oled.clear();
  oled.println(b);
  delay(1000);
  oled.clear();
  oled.println(c);
  delay(1000);
  oled.clear();
  oled.setCursor(50,50);
