The Hitachi HD44780 controller and its compatible controllers like Samsung KS0066U have become an industry standard for these types of displays. - - This library allows easy interfacing with a HD44780 compatible display and can be - operated in memory mapped mode (LCD_IO_MODE defined as 0 in the include file lcd.h.) or in - 4-bit IO port mode (LCD_IO_MODE defined as 1). 8-bit IO port mode is not supported. - - Memory mapped mode is compatible with old Kanda STK200 starter kit, but also supports - generation of R/W signal through A8 address line. - - @see The chapter Interfacing a HD44780 Based LCD to an AVR - on my home page, which shows example circuits how to connect an LCD to an AVR controller. -
