I'm starting my first major project, to build a PID controller for temperature and humidity. That parts going ok, but i'm confused about which display to pick, so many choices, so many different controllers.
I'm within the UK and my preferable supplier is RS. I'm ideally after a 20x4 monochrome LCD. If possible controlled by serial connection, i'm using a mega so its no problem is its not.
Unfortunately they don't seem to sell any HD44780 controlled displays.
This is the closest I've manage to find:http://uk.rs-online.com/web/p/lcd-monochrome-displays/5326818/
It's controlled by a ST7066U. Pin outs on page 9 of the datasheet:http://docs-europe.electrocomponents.com/webdocs/06dd/0900766b806dda1c.pdf
Other controllers available:
PCF 2119RU/2/F2 COG
Can i get recommendations on whats compatible and has good library support?
