Hello,
I tried different things to get something displayed on "Monochrome 0.91" 128x32 I2C OLED Display - STEMMA QT / Qwiic"
https://www.adafruit.com/product/4440
For example I used circuitpython 8.1 and micropython 1.20 on an raspberry pico.
I can scan the i2c id which works on circuitpython and micropython.
What is the easiest way to check that the OLED is functional, i.e. show something on it, e.g a single pixel.
Which libraries do I have to copy to the lib folder on the CIRCUITPY drive. And which are the minimal circuitpython lines to get something displayed. I have a breadboard and product 4209 (STEMMA QT / Qwiic JST SH 4-pin to Premium Male Headers Cable - 150mm Long) to connect the raspberry pico with the OLED.
Thanks a lot for any hints.
Best regards,
Raphael

Hello, my quesion can be closed.
I used the code available at:
https://wokwi.com/projects/309427357921313345
There are also schematics show. I just copied the code, changed the scl and sla pins according my setup and wow there appeared something on the oled. so it seems it is working.
I have attached the code and the schematics as png file.
Best regards,
Raphael
