Hi,
Has anybody had any luck getting the 40x4 from buydisplay to work in parallel mode? (https://www.buydisplay.com/character-arduino-40x4-lcd-display-datasheet-ks0066-white-on-blue)
Looks like the liquidcrystal440 library should work. (GitHub - arduino-libraries/LiquidCrystal: Liquid Crystal Library for Arduino)
But I am just getting a lot of horizontal lines on the screen. Tried to use the noDisplay() command, and it did not do anything. Almost like it is not switching to 4 bit mode?
Appreciate any pointers.
Thanks
Mark
