DISPLAY ST7920

Please be more precise when describing your problem. What do you mean by "I can not do it"? what problem are you facing?

The complete explanation of how to use bitmap on with ST7920 is given here

https://circuitdigest.com/microcontroller-projects/graphical-lcd-interf…

In the program given in the above link cut the following lines from the void loop function 

 clearLCD();
  u8g.firstPage();  
  do {
     picture();
  } while( u8g.nextPage() );
  delay(3000);

And paste it at the end of setup() function and your screen will boot with the bitmap image. 

Hello
knows my program and the boot image and then the program and starts again
could you please look in advance thank you

code looks fine, what problem r u facing?

Hello
the logo oscillates between the program,
I would like to boot on the logo with a delay and then pass on my program, if you can help me, thank you
