The text outside the screen border appears on the other side

[aivs]

Hi!
I use OLED display 256x64 with controller SSD1322 + STM32F108.
I'm trying to make a function to move text outside the screen border, but the text starts to appear on the other side.
How to avoid the appearance of text on the other side?

int main(void) {
    u8g2_Setup_ssd1322_nhd_256x64_f(&u8g2, U8G2_R0, u8x8_byte_4wire_hw_spi, u8x8_stm32_gpio_and_delay);
    u8g2_InitDisplay(&u8g2);
    u8g2_SetPowerSave(&u8g2, 0);
    while(1){
        u8g2_SetFont(u8g2, u8g2_font_profont29_tf);
        char str = "Value";
        for (int16_t x = 0; x<256; x++) {
            u8g2_DrawUTF8(u8g2, x, 0, str);
        }
    }
}

You need to activate u8g2 16 bit mode, see faq.

Thanks, but it did't help. I've uncommented line in u8g2.h

#define U8G2_16BIT

The page goes to the right and appears completely on the left

Uncommenting U8G2_16BIT will solve the problem. However you need to recompile everything. Additionally: Maybe you have modified the wrong library if you have multiple u8g2 lib versions on your hard disc.

Yes! With this code it's work!
I think the problem in my code.

      u8g2_ClearBuffer(&u8g2);
      u8g2_SetFont(&u8g2, u8g2_font_profont29_tf);
      u8g2_DrawUTF8(&u8g2, 0, 64, "Value");
      u8g2_SendBuffer(&u8g2);

      for (int16_t x = 0; x<256; x++) {
    	  u8g2_ClearBuffer(&u8g2);
          u8g2_DrawUTF8(&u8g2, x, 64, "Value");
          u8g2_SendBuffer(&u8g2);
      }
