E3002 Single Wire Serial LCD Interface
E3002 Single Wire Serial LCD Interface
The E3002 Single Wire Serial LCD Interface allows standard LCDs from 1×8 to 4×20 sizes to be easily controlled with a single serial pin using only one ASCII byte for standard or custom characters, or two bytes for instructions such as placing the cursor. Serial data is jumper selectable for either 19.2Kbaud or 115.2Kbaud with echo. An elastic buffer stores up to 128 bytes of serial data. All LCD timing is handled by the E3002 simplifying the display process for the host micro. This is accomplished using a command set compatible with the HD44780 and other variant LCD controllers. Non-standard commands and delays are easily handled with special instructions. The E3002 is compatible with both 3.3V and 5.0V LCDs using a jumper. The board includes contrast adjustment and space for a backlight current limiting resistor. The E3002 mates with the standard 1×16 LCD connector. A low dropout voltage regulator ensures proper logic levels to the LCD.
