LCD Adafruit 4x20 Display

Post by PicoPuls »

Trying to use the Diplay Component OLCD Adafruit 4x20

The actual component used is this
http://www.mouser.se/search/ProductDeta ... 420DZW-AG5

The diplay is dark, but by touching some of the open connections with the finger
fills the rows with random signs. It confirms that power is ok.
I have also tested other ports with negative result

Is there an error in the connection ? Is there any sample code ?

Best regards
BO

Some jumpers were found and the red lines are my guesses for correct settings
Still it doesn't work. I give up for now.
If anyone has an idea it would be most welcome
Thanks and best regards
