Problem regarding LPC1768 microcontroller hardware I2C interrupt driving OLED

Hello, I have a question that I want to use the LPC1768 microcontroller hardware I2C interrupt to drive OLED. I am a beginner. I just touched the LPC microcontroller. After the register operation lights up the LED, I want to light up the OLED. My OLED is four-wire. For I2C communication, I read the Chinese manual of LPC1768 and the manual of OLED ssd1306 and performed some porting of the existing programs, but the result is still not able to light up the OLED. I don’t know what is going on, so I came to ask for advice. What's wrong?
Can you please help me if you have time? Thank you!
