FAQ

Question:I tried the "I2C1-OLED.py" example. The upper half of the display looks good but the bottom half contains noise or very garbled data.

Answer:

The problem should be caused by the speed setting in the codes.
You can increase the speed and test again.

Question:What version of Thonny are you using?

Answer:

I have the 4.1.2 version. Try this version if you want.
