"This is a RoHS compliant I2C Serial LCD Daughter board that may be linked to a popular 16×2 or 20×4 Character Display Module that supports four-bit mode. All Character Modules bought on our web site aid 4-bit mode, and nearly all commercially available 16×2 and 20×4 line individual modules guide it too.
This board has a PCF8574 I2C chip that converts I2C serial statistics to parallel facts for the LCD show. There are many examples at the internet for using this board with Arduino. Do a look for “Arduino LCD PCF8574“. The I2C deal with is 0x3F via default, but this could be changed via 3 solder jumpers furnished on the board. This permits up to a 3 LCD displays to be managed via a single I2C bus (giving every one it’s personal address)
Specifications and Features:5V power supply.Serial I2C control of LCD display using PCF8574.Backlight can be enabled or disabled via a jumper on the board.Contrast control via a potentiometer.Can have 8 modules on a single I2C bus (change address via solder jumpers)address, allowing.Size :41.6 x 19.2 mm.

A 16x2 LCD means it can display 16 characters per line and there are 2 such lines. In this LCD each character is displayed in 5x7 pixel matrix. This LCD has two registers, namely, Command and Data. The command register stores the command instructions given to the LCD. A command is an instruction given to LCD to do a predefined task like initializing it, clearing its screen, setting the cursor position, controlling display etc. The data register stores the data to be displayed on the LCD. The data is the ASCII value of the character to be displayed on the LCD. Click to learn more about internal structure of a LCD.

This is the latest evolution of our serial LCD. Included on a single board is a 16x2 LCD and an embedded circuit based around a PIC 16F88 and others. The Serial LCD is a simple and cost effective solution for interfacing to Liquid Crystal Displays (LCDs) based on HD44780 controller. The module takes incoming 9600 bps TTL level signals and display those characters on the LCD screen. Only three wires +5V, GND and Signal are needed to interface to the LCD.

Features:
  • Operational Backspace
  • Simple 3 pin Interface to control LCD from 9600 baudrate from any microcontroller
  • Contrast adjustment Preset
  • Backlight can be controlled from softwareFull control of LCD from serial data
  • Auto-wrapping of displayed data
  • Incoming buffer stores up to 80 characters
  • Pulse width modulation of backlight allows direct control of backlight brightness and current consumption
  • All surface mount design allows a backpack that is half the size of the original
  • Faster boot-up timeBoot-up display can be turned on/off via firmwareUser definable splash screen

Specifications:
  • The serial LCD should only be powered by 5V DC
  • Higher than 5.5V will cause damage to the LCD
  • The serial LCD uses 3mA Backlight turned off and ~60mA with the backlight activated

Seven-segment displays are electronic display devices used as an easy way to display decimal numerals and an alterative to the more complex dot-matrix displays. The LDS-C303RI, a common seven-segment display, will be examined. Common anode vs. common cathode will be outlined.LED drivers such as the CD74HC4511E will also be discussed. Design applications such as digital clocks and electronic meters will be covered briefly. The following will detail the necessary requirements to implement a display into a circuit. This application note will also provide the basic functionality of a seven-segment display. In terms of hardware, the implementation of the display into a counter using a CD74HC4511E driver will be discussed. Schematics are included in order to explicitly show the correct implementation of the display into a simple binary counter.

Methods:
  • When dealing with seven-segment displays, there are two types
  • Common anode and common cathode; in common anode all the anodes on the display are tied to a common pin, typically the power source and the LED are controlled via the cathodes with ground being on and power being off
  • In common cathode all the cathodes are tied to a common pin, in this case generally Ground, and the LED are driven by the state of the anodes where ground is off and power is on
  • Hence a seven-segment plus decimal point package will only require nine pins, though Commercial products typically contain more pins in order to match industry standard pin outs


Features:

  • Low current operation
  • Excellent character appearance
  • Easy mounting on P.C. Boards or sockets
  • I.C. Compatible


Specifications:

  • The Serial 7-Segment Display can be controlled in one of two ways
  • Serial TTL communication
  • SPI serial communication
  • Regardless of which method you use to communicate with the display, you must always send your display data in 4-byte packets, and special commands in 2-byte packets
  • There are two methods of sending serial data to the Serial 7-Segment Display, TTL level serial communication or SPI.
