ERM2004SYG-2 is 20 characters wide,4 rows character lcd module,SPLC780C controller (Industry-standard HD44780 compatible controller),6800 4/8-bit parallel interface,single led backlight with yellow green color included can be dimmed easily with a resistor or PWM,stn-lcd positive,dark blue text on the yellow green color,wide operating temperature range,rohs compliant,built in character set supports English/Japanese text, see the SPLC780C datasheet for the full character set. It"s optional for pin header connection,5V or 3.3V power supply and I2C adapter board for arduino.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

Reverted the SPI functionality to Crystalfontz CFA634 legacy implementation where the MISO line is used as a busy indicator instead of the module"s unused transmit line. Firmware will migrate from v3.1.5 to v3.1.6.

Pricing at the time of the PCN was issued was published as TBD. This update notices publishes pricing for the CFA634 family of modules effective 2013-07-01

As part of our continuous improvement process, the CFA634 family of modules has been redesigned to fall more in line with our other Value Add families of intelligent modules.

The firmware has been revised to support the hardware changes from the Samsung S6A0073 LCD controller to the Rockworks RW1067, and the Holtek HT48R30 one-time-programmable controller being replaced with the Cypress PSoC CY8C27443 for improved functionality.

Samsung S6A0073 LCD controller is EOL. Module has been redesigned to incorporate the Rockworks RW1067. The Holtek HT48R30 one-time-programmable controller replaced with the Cypress PSoC CY8C27443 for improved functionality.

The previous CFA634-YMC-KS and CFA634-YMC-KU (new CFA634-YDI-KS and CFA634-YDI-KU) changed from STN to double negative (FFSTN) LCD for improved appearance.

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.

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.

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().

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).

Answer: For the segment type LCD module, if you need to modify the outline size or display content, we will start the drawing paper for your checking.

This is an industry standard HD44780 based controlled 4 lines x 20 characters LCD display with WHITE characters on BLUE background and backlight. It is a parallel interface so you will need 7 GPIO pins for 4-bit mode or 11 GPIO pins for 8-bit mode to interface to this LCD screen
