SSD1306 OLED Allocation Failed

Projects Programming

Hi,I'm beginner at Arduino.I trying to make some projects.but I get this error message on Adafruit SSD1306 library.I read something about this is because of low flash.But I can't reduce my variable,all necessary.Can you help me please?
Here is my code.

Your topic was MOVED to its current forum category which is more appropriate than the original as it has nothing to do with Installation and Troubleshooting of the IDE

You can save a small amount of SRAM by using the F macro in all print() statements:
replace this

display.print("Y:");

with this

display.print(F("Y:"));

But the screen and the SD card use up 3/4 of SRAM on the ATmega328, so you probably need an Arduino with more memory.

This does NOT do whatever you think it might do. Look up the "C/C++ comma operator".

if((mpu6050.getGyroX()>0,7)

Thanks for answer.I have an ESP32 Devkit.Can I use same code with new connections?
