@Jorgen
Thx ;)
Yes it is one with yellow band on top. So everything within the first 15 pixels is yellow instead of blue.
But I'm not really happy about this cheap OLED displays, because they did not have any CS signals. Means you can not add multiple displays on one SPI bus :/
So I already ordered some with CS for 3.30 USD on aliexpress ;)
@Gordon I had these random pixels only with the arduino library connected on my Teensy3.1
It seems, that it depends on the power supply.
My example just uses the VDD/GND of pico or the pins A5/A7 setting to high/low to give 3.3V
both is working great without any random pixels.
