4x20 lcd display datasheet brands

Adding to what N1VG posted, you can indeed control this module, or any other HD47780-based character LCD module for that matter, with six lines. If you"re using an Arduino as the brains for your project, the LiquidCrystal library that comes with the Arduino IDE will run a HD47780-based module from six pins without having to manage things like passing nybbles to the module - you can just include LiquidCrystal.h, declare a new object (e.g., LiquidCrystal lcd(2,3,4,5,6,7); to use pins 2-7 to control the module), and just shoot data to it with the print() and write() commands. The library will handle the rest.

You can get by with 6 I/O lines for an HD44780. Just keep the RW pin pulled low (assuming you don"t need to read from the display) and connect only the high 4 data lines. You"ll need to send it a command to put the bus into 4-bit mode, and of course you"ll have to write to it one nybble at a time, but that"s not hard to do.

Not sure if this is normal. My LCD, using the liquidcrystal library, wraps to the third line after finishing the first (then it goes to the second, then the fourth), but addressing each line is normal when using setCursor().

The "solution" I came up with was simply to use the cursor positioning feature to write to the lines I wanted. Since you"re writing strings anyway, it"s not terribly difficult to do. If you"re making a display for a project, just account for what ends up on what line.

Does anyone know where I can get a pre-manufactured ribbon cable assembly suitable for use with this LCD? Soldering a thru-hole connector or pin header to the panel is something that can probably be done in our shop, but assembling our own cables from scratch may be a bit beyond our ability to do routinely... We just need a 6" cable with (say) female sockets (16x1) at both ends... The other end to plug into a suitable header on an Arduino-based PCB... Thanks for any tips, -Mike

I made a tutorial (in portuguese) about how to use, create custom characters and design menus for the LCD display. Take a look: http://engenheirando.com/arduino/displaylcd/

Can anyone confirm if this works with an Arduino Uno? Following these directions (http://arduino.cc/en/Tutorial/LiquidCrystal), no matter what I do I can only see solid blocks on two of the 4 rows when the pot is turned all the way down. Is this because the Arduino library is for a 16x2 character LCD and this one is a 20x4?

I forgot to buy breakaway male header pins for this LCD module. However, I do have spare female headers from a previous project. Would I be able to use the female headers?

This display has a parallel interface, so it will require about 6 I/O pins to run. The parallel protocol is complex, but there are good LCD libraries out there which make it easy to use. The difference between this and a serial display is that the serial display will only require one I/O pin.

If you use straight headers, the clips used to anchor the lcd to the board get in the way when you try to plug it into a breadboard with power rails on the side.

A very useful LCD - and, if you need it to take even less than 6 pins, there"s a library (by Chris Parish) for using it with a 74HC595 shift register that reduces it to 3 digital output pins. The library and Chris"s tutorial is here - http :// cjparish.blogspot.com/2010/01/controlling-lcd-display-with-shift.html

@Twiddler: Yes, it"s possible to write too fast. Check the write cycle timings in the datasheet. The enable signal can"t be cycled faster than 2MHz. Also after each command sent to the LCD, you have to wait until the busy flag is clear, or delay several microseconds to milliseconds (depending on which command).

A 20x4 LCD display is very basic module and is very commonly used in various devices and circuits. These modules are preferred over seven segments and other multi segment LEDs. The reasons being: LCDs are economical; easily programmable; have no limitation of displaying special & even custom characters (unlike in seven segments), animations and so on.

A 20x4 LCD means it can display 20 characters per line and there are 4 such lines. In this LCD each character is displayed in 5x7 pixel matrix. This LCD has two registers, namely, Command and Data. This is standard HD44780 controller LCD.

Everyone loves character LCD, is cheap and works out of box! This is 20x4 character LCD module. But the need for 6 to 10 GPIOs is the pain :) It takes most of GPIO of Arduino and other microcontroller. Now with this I2C or Two wires interface LCD, you will save a lot of GPIO for your sensor and motor control.

LCD shield after connected with a certain sensors or SD card. However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, you can still program this LCD with the correct I2C address. It is fantastic for Arduino based project.
