- One minor error, these modules do not accept serial data, but as desired
- by the original poster, they do work with either 4 or 8 bit data. There
- are a couple of other handshaking signals that need to be implemented also.
-
- These LCD modules are really slick. They (like many other manufacturers')
- use the Hitachi HD44780 driver chip which takes care of most everything.
- You can send it a variety of cursor movement/ display shift commands, as
- well as download 8 user defined characters. Very easy to use!!!
-
- Oh, if anyone knows the phone number for Gateway Electronics, try them also.
- They have some older units for only $5.
