The OLED seems quite easy to wiring and use, but frequently met that the OLED works well in one code, doesn't work for another one, works well in one circuit, doesn't work for another one.
any suggestions to make it stable?
Thanks

Can you post schematics of where it does work next to where it doesn't? Without those, you'll only get guesses.

 

AND pleae explain what you mean by "in one code", that is not a term that I am familiar with. Organic LEDs are different and so the forward voltage to current relations are different as well.

The basic example is it works for: IDE build in: ssd1306_128*32_I2C; not works for: ssd1306_128*64_I2C

The 'code' here I mean a 'program' that uploaded, should I call it a sketch?

 

The two examples that you quote are for two different OLEDs having different display resolutions. Your OLED will only work with the correct one.

You solved my headache.

Code is much more descriptive than "sketch" , and now it has become clear to me that the quetion is about the operation of an ORGANIC LED DISPLAY device, not simply an OLED by itself. That i an entirey different topic.
