Der Code aus #43 muss so aussehen:

Code 
#include <Wire.h>
#include <U8g2lib.h>
#include <Arduino.h>

//U8G2_SH1106_128X64_NONAME_1_2ND_HW_I2C u8g2(U8G2_R0, U8X8_PIN_NONE);
U8G2_SH1106_128X64_NONAME_F_2ND_HW_I2C u8g2(U8G2_R0, U8X8_PIN_NONE);
u8g2_uint_t offset;
u8g2_uint_t width;
const char *text = "Hallo";

void setup(void) {
  u8g2.begin();
  u8g2.setFont(u8g2_font_lubB18_tr);
  width = u8g2.getUTF8Width(text);
  u8g2.setFontMode(0);
}

void loop(void) {
  for (int i = 0; i < 128 + width * 3; i++) {
    u8g2.firstPage();
    do {
      u8g2.setFont(u8g2_font_helvR24_tf);
      u8g2.drawUTF8(128 - i, 48, text);
    } while (u8g2.nextPage());
  }
  u8g2.clearBuffer();
}
