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
