Output Russian text to OLED 0.96 129x64 display via arduino?

Question

Arduino

Hey! I’m trying to display something in Russian text, he downloaded the iarduino library, but it’s completely buggy, it plows according to the finished example, and if it changes even a little, it doesn’t display anything at all. something nonsense, not even hieroglyphs, I tried to transfer the Russian font from the iarduino library, but garbage was still displayed, here is the last code:

#include <OLED_I2C.h>

OLED  myOLED(SDA, SCL, 8);
                                        
extern uint8_t RusFont[];   
byte page = 1;
String text = "это типо текст ";


void setup()
{
    myOLED.begin();                                                    // Инициируем работу с дисплеем.
    myOLED.setFont(RusFont);  
     
}

void loop()

{
  myOLED.clrScr();
  myOLED.print(text,0,19);
  myOLED.update();

  while (1);
}

and here's what's on the display: https://www.youtube.com/watch?v=ONZJlgqFEnA

here's what is written in this font, to be honest: I don't know how to check it, but this font was the default:

};

there is also a Ukrainian font, but the output is the same. tell me how to be?

Answer 1

The Arduino IDE works in Unicode, so if you directly specify a Cyrillic string there, it will be written in Unicode, two bytes per character. Just for fun, take a look at sizeof(text).
The easiest way is to fit the characters you want to use in the first 127 (or rather 112) characters and create a custom font (it's easy), and write like "ABVGDE*ZIJKLM"

Answer 2

You need to carefully study the "Fonts" implemented in this library " OLED_I2C.h ".
If there are NO Cyrillic fonts, change to a library where there are Cyrillic fonts.
