 scattered pixels can also mean the wrong driver. Are you sure you're using an SSD1306 and not an SH1106?
Hi @scruss. I'm using SSD1306.

Thanks

 Pull-Up resistors are usually 5-10kOhm. But the the display works with I2c, then there may be pull-up resistors on the display already.
They are placed between the signal wire (SDA or SCL) and Vcc.
I'll check it @Roberthh.

Thanks

Re: SSD1306 1.3" OLED (128x64)

Hi,
I think I'm having some issues in wiring. I mean, I gave the correct connections, but sometimes it will show scattered pixels and sometimes it shows correct pixels and images as per the requirement.

The driver defaults to 0x3c: https://github.com/micropython/micropython/blob/bc7822d8e95c40a9d5e403fd22c82b1bbad53b8b/drivers/display/ssd1306.py#L113 Pass your address to the driver constructor: oled = SSD1306_I2C(WIDTH, HEIGHT, i2c, addr=0x3D) Hi, I passed that earlier itself. After passing that 0...

 Do you get a result from this part?:
print("I2C Address : "+hex(i2c.scan()[0]).upper())
Yes, I'm getting that I2C address and I2C configuration part.

Code: Select all

I2C Address      : 0X3D
I2C Configuration: I2C(0, freq=200000, scl=9, sda=8)
