Serial LCD Kit #117 w 16X4 LCD - Basic Stamp

This listing includes the Serial LCD #117 Kit plus an Emerging Technology ED100020TRU 16X4 LCD as shown in the photo. This is in kit form suitable for assembly on a solderless breadboard There is no printed circuit board.

This Emerging Technologies 16X4 LCD is not the sexiest display unit. It is somewhat oddly shaped and there is no backlight. The interface uses ten pins (vs the standard 14) by providing access to only four of the usual eight data bits. However, the LCD #117 uses the 4-bit transfer mode and thus is compatible with this display.

Terminals 11 and 12 on the LCD display may be used to control small discrete LEDs on the display. A red LED on the top and a green one on the bottom. (Not a big selling point).

The LCD #117 Kit operates at 9600 baud. This unit might be interfaced with a Basic Stamp, BasicX BX24, Arduino, Microchip PIC or any processor capable of sending serial at TTL levels (Near +5 VDC when idle).

My intent in offering this is to provide hobbyists with a functional serial LCD at a very minimal cost.

The LCD #117 Kit provides an interface between a Microchip PIC, Parallax Stamp, BX24, Arduino or similar and an LCD having an HD44780 interface. I believe it is the most powerful serial to LCD unit available on the market and the least expensive. I have sold several thousand over the past four years.

Note that some of the LCD #117 features are not applicable when using this Emerging Technology display. These include LED backlight control (there is no backlight on this display) and the 3 and 4 block wide "big" number capability and the customized splash display screen which are for 20X4 displays only.

Features of the LCD #117 PIC Processor..

• 9600 Baud TTL Interface - Non Inverted.
• 64 Byte Receive Buffer
• Programmable LCD Geometry (2X16, 2X20, 2X24, 2X40, 4X16, 4X20) - saved in EEPROM.
• Eight User Defined Characters (saved in EEPROM).
• Programmable Tab Size (saved in EEPROM).
• Programmable Cursor Style (saved in EEPROM).
• Output for "beep" function. (The interfacing audible device is not included with this kit).
• Rich Cursor Instruction Set including, clear LCD, clear current line, cursor to defined line, cursor to defined column, cursor up, down, back, foward, new line and "beep".
• Four addressable TTL level outputs (15 mA)

This listing includes;

• Programmed PIC Processor (18-pin DIP).
• 4.7K Resistor for Processor Reset Terminal
• 330 and 4.7K Resistor for biasing contrast on the interfacing LCD.
• 5 Volt LED for testing.
• Lengths of 22 awg solid wire (four colors) suitable for use with a solderless breadboard.
• 16 X 4 Emerging Technology LCD with no backlight.
• 12-pin header for the LCD.
• Documentation.

Note that a source of +5 VDC is required. The current drain is less than 10 mA.
