Serial LCD Driver twig is an UART based LCD1602 display (Hitachi HD44780 or a compatible LCD). It can control LCD1602 only with two I/O port pins (UART Tx and Rx).The VCC and GND are the only additional pins required for operation. Conventional LCD drivers use 7-11 I/O port pins, whereas Serial LCD twig saves all these additional I/O pins. Serial LCD twig uses AT89S52 for implementing the UART Driving logic. Now has been updated to v1.0b.
