I was working with the i2C LCD module and wanted to use only the wire.h instead of the i2c liquid crystal library. I want to ask if that is possible or n…

Displays are weird, because they can be in 4-bit or in 8-bit mode or in a certain state. Special initialization code is required to capture the display. LCD displays are weird, because they are not all the same. LiquidCrystal libraries are weird, because they are no longer maintained or Arduino us…
