I changed the code from the guy, where he changed the code little bit but I still got error. Here it is:
Better to supply the complete code in code brackets.
It's written in forum requirements which you obviously did not read.
Hello. I found one code that works on uno board in arduino. The problem is that I have a nano board.
The second problem is that the display is a used ssd 1306 and I have a display sh1106.
Is there any way to modify this code to make it work under my conditions?
here is the original code:
#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#define OLED_RESET -1
#define SCREEN_ADDRESS 0x3C
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
#define NUMFLAKES 10
#define LOGO_HEIGHT 16
#define LOGO_WIDTH 16
static const unsigned char PROGMEM logo_bmp[] =

I have merged your cross-posts @anon2855690.
Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.
Repeated cross-posting can result in a suspension from the forum.
In the future, please only create one topic for each distinct subject matter. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide. It contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
sorry this topic was kinda different from other and older topic. It has same display but the point of the topic is different
This i s not a problem, because Arduino Uno and Nano boards uses the same microcontroller and, therefore, are compatible with software each other.
so, only problem is these library for displays, right? In code is ssd1306 display. but I need sh1106 display.
If you sure on the code...
I see some weirdness in the program, so I doubt how it works...
is it a endless loop?
yeah, exactly
Hey, guys. I want to give you some advice. I'm a beginner and would like to try out my newly bought stuff. I'm thinking of a sh1106 display and an arduino nano board. Could you recommend me some nice code where the display could create different animations and stuff? I'll be very happy for any code and would love to try it out.
You'll probably have to write the code yourself. And, usually it's easier to write your own code than to understand & modify somebody else's. (I didn't say easy... I said easier. 
)
I don't know anything about the display but some quick searching found that Adafruit has an Arduino library for it, which should simplify your coding.
Just as a general comment, it will take quite a bit of memory to store image "frames" so if you can generate the image(s) in software (moving or turning pixels on & off in a loop, etc.) you should be able to "do more" but that depends on what you're trying to do.
Shoot! I'm all ears.

I'm sorry. I'm sorry. I should have said I wanted your advice. Not that I'm going to give you advice 
I wanted advice in a different way but I'll stop. Im sorry
