Re: LCD Garbled ness :(
Any chance you can share your init script please? So your saying with wiring on OLED as 4bit. Init script set to 8bit then modify down to 4bit and it works ?

Would a small resistor not do the same thing?
Thanks

Re: OLED 16x2 HD44780 woes
Experiencing very similar issues http://www.raspberrypi.org/phpBB3/viewt ... 88#p496788 However, I have more wiring as I have not disconnected backlight (15/16).
I will follow and keep updated if I get anything back.

Hi All, On occasion when starting my Pi with my LCD connected via breadboard the LCD (which is not really an LCD its an OLED, but connects the same way) displays garbled rubbish on the display.
