1.3 OLED with IRremote crash?

Using Arduino Programming Questions

Hello there i have problem with this code
If I add IRremote.h and comfort it, the screen that was working fine won't come out
But if I take IRremote.h out, the screen comes out well again. Is there a solution for this?

#include <IRremote.h>
#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SH110X.h>

/* Uncomment the initialize the I2C address , uncomment only one, If you get a totally blank screen try the other*/
#define i2c_Address 0x3c //initialize with the I2C addr 0x3C Typically eBay OLED's
//#define i2c_Address 0x3d //initialize with the I2C addr 0x3D Typically Adafruit OLED's

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels
#define OLED_RESET -1   //   QT-PY / XIAO
Adafruit_SH1106G display = Adafruit_SH1106G(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

Have you tried checking the return value from the display.begin(...) call to see if succeeded?

Please define what you mean by "won't come out"? No one can see what you see.

And please tell us what board you are using.

ah i forgot explain what i use
i use UNO
and i check Verifying that it works as in Example

aaaa
aaaa1920×2560 369 KB

but only use #include <IRremote.h> oled It doesn't print anything

I'm still a beginner, so I'm sorry for not explaining it

The Uno only has 2K of RAM. Your example program uses in the neighbourhood of 530 bytes of RAM statically. And the library for your display is allocating 1K at runtime for its buffer. If IRremote uses more 2K-1K-530 = 494 bytes of RAM, your program crashes. If IRremote even comes anywhere close to using 494 bytes of RAM, your program likely runs out of stack space and crashes. In either case, it doesn't run as you'd want it to.

And the solder connections on the display need touching up. SCK and GND especially.

Wow thank you so much! I can finally fall asleep. My soldering skills are still terrible, but I'll fix it! Thank you so much for your advice!
