I have code to connect, and use Arduino cloud Iot. It works fine and sends sensor data from my boat battery.
I want to install a small oled display, using U8g2lib .
As soon as I include U8g2lib in the code, it will not connect to my Thing in the cloud.
It works fine separately, so when only using the Oled display.
I have tried bypassing the U8g2lib by using Adafruit_SSD1306 but can't get the oled to work this way.
It is a 6 pin Oled
Any help appreciated
