Grove - Serial LCD
Serial LCD Driver 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 saves all these additional I/O pins. Serial LCD uses AT89S52 for implementing the UART Driving logic. Character, integral number and float number is supported.
Serial LCD includes:
- A 16 x 2 LCD
- A module reset button.
- A variable resistor(R4) for LCD contrast ratio adjustment.
- Two LED indicators:
- Green LED (D1) indicates the Power.
- Red LED (D2) indicates the type of command (ON is control command; OFF is character command).
