I'm working on an embedded linux project that needs a multiline LCD. And I can allot only an 8pin GPIO port for it. I'd like it to be atleast 2 line, but the more lines, the better. Could someone help me find one?
Most of the small text LCD modules use the same processor. They also have the same interface. This interface can use either an 8 bit bus or a 4 bit bus. In 4 bit bus mode they require 4 lines for the bus plus 2 lines for control purposes. Take a look at this link: https://www.myke.com/lcd.htm for an example. Search on google there is a lot of info regarding this
