Post by: Mohdsyukri01 on Apr 17, 2019, 07:40 am
I have problem with i2c 128×64 oLed not appear properly.

That screen just appear little on top only and the rest of them just dot at the bottom.

I use Arduino Nano and upload sketch from Adafruit ssd1306. I've tried both power pin 3.3v and 5v,but what i got is same problem.

Hope someone can help me to fix this..Thanks

Make sure you select the right sketch "ssd1306_128x64_i2c" and also the height settings are correct in Adafruit_SSD1306.h file.

Before saying the module might be faulty, you may want to check basic stuffs like SCL to arduino pin A5 and SDA to arduino pin A4 and power it by a good 5 volt supply.

You also may also want to check the address (http://playground.arduino.cc/Main/I2cScanner.) of your OLED and make sure same address is there in your ssd1306_128x64_i2c sketch or change of needed.

i also found below link on similar issue.
