@MaBe it worries me that you're using some strange module
SSD1306_I2Cwhich doesn't exist in Espruino's repositories. Maybe try using the properSSD1306module first and see if you can get it working with that?The random dots happen if you have managed to initialise the display and turn it on, but haven't sent any data using
flip()- so maybeflip()is broken in the module you're using?
