Hello @Mike_ST i tried with pull-up resistors 4.7k but still no response from oled display.It works fine in all the videos on youtube even without pull-up resistor. Can you suggest any other trouble shoot?

No i have connected them directly, i will try using pull up resistor and let you know

I've tried many many libraries but no luck. The screen remains blank. No response.But the same screen works with arduino. So i know connections are fine, only problem with coding.Here are the libraries that I've triedhttps://github.com/vookimedlo/stm...

I'm using NucleoF401RE. The issue is that GPIO Read pin is always SET. There is nothing connected to board. No pull-up resister connected. When i try to debug, HAL_GPIO_ReadPin always returns Pin_Status as SET.

Im using stm32 bluepill im trying to use OLED 128x32 i have tried libraries but nothing is working,same OLED worked with Adruino Mega. If anyone knows what might be the issue please let me know[SOLVED]

Im trying to use ST7920 GLCD with STM32F401RE with I2C connection,im still new with programming so im trying to find a library when using I2C,most videos and libraries i found are for SPI connections..if anyone has a library pls help thank you
