tago Posted March 29, 2019 Report Share Posted March 29, 2019 (edited) Hi, i wonder how to test new displays for bad pixels. I have some standard 128x64 OLEDs and some character LCDs i'd like to test. My first idea was to enable/disable all pixels at once. Is this sufficient? If yes, which char displays all available pixels per char? Thank you! Edited March 29, 2019 by tago Quote Link to comment Share on other sites More sharing options...
tago Posted April 1, 2019 Author Report Share Posted April 1, 2019 According to the HD44780 datasheet i need to send 1111/1111 to the display to enable all pixels per char, but don't know the string equivalent is to enter in the .ngc file.
