This thread is a collection of posts and links about using character based LCD's with the Hitachi 44780 controller or compatible. Currently it includes therory, and implementations or PIC and AVR in ASM Swordfish Basic and c. Included are tutorials to convert the LCD interface to SPI, I2C and shift register based interfaces.
