USB interface for parallel LCDs
Adding a cheap LCD to your PC is a popular diy project for many beginners in electronics. The parallel port however, is dead. It’s obsolete. It’s big…ugly and just awful. The solution? Add a USB interface to your existing LCDs. The circuit interfaces to a standard HD44780 compatible LCD and emulates the CrystalFontz serial protocol over a virtual COM port created by the FTDI chip. This enables you to use already existing software to speak to the LCD, for example the popular program LCD Smartie. The circuit uses an AVR microcontroller, the tiny2313, and a USB chip from FTDI.
