1602 lcd modules with serial manufacturer

ERMC1602SBS-2 is 16 characters wide,2 rows character lcd module,SPLC780C controller (Industry-standard HD44780 compatible controller),6800 4/8-bit parallel interface,single led backlight with white color included can be dimmed easily with a resistor or PWM,stn- blue lcd negative,white text on the blue 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.

This module works with at least the LiquidCrystal I2C and LiquidCrystal_PCF8574 libraries available in the Arduino library manager. Address 0x3F worked for me since the A0, A1, and A2 jumpers are not shorted.

Recently purchased unit has a different address than the same part number purchased a year ago. It seems that if the small board is marked MH, the address is not going to be 0x27 or 0x20 but 0x3F. With that change of address, this display works and looks great.

Google for LCM1602 and you will find many pages that mention the board - including the pinouts stated above and sample programs using the Arduino library.

Heres the scoop. The library that works with this chip set is available at this link. http://www.play-zone.ch/en/fileuploader/download/download/?d=0&file=custom%2Fupload%2FFile-1345667375.zip

I liked the idea of the 4-wire interface, but I was disappointed that no documentation was available for this part. However after a night of hacking I got it to work with my Arduino Uno. I thought Id pass along the following information to spare others the trouble.

On the software side, you have to download and install a new LiquidCrystal_I2C library for Arduino, which has the capability to talk to the LCD display over the I2C bus. Heres a link to the library. Follow the example code for the DFRobot board, which turns out to have the same configuration as this LCD, and it should fire right up for you. The LCD has white characters on a backlit blue background, and looked great.

This is I2C interface 16×2 LCD display module, a high-quality 2 line 16 character LCD module with on-board contrast control adjustment, backlight and I2C communication interface. For Arduino beginners, no more cumbersome and complex LCD driver circuit connection. The real significance advantages of this I2C Serial LCD module will simplify the circuit connection, save some I/O pins on Arduino board, simplified firmware development with widely available Arduino library.

This Blue LCD display module has a high-speed I2C serial bus. With the limited pin resources, your project may be out of resources using normal LCD shields. The LCD display is a 2x16 character STN white display with a blue LED backlight. With the I2C interface LCD display, you only need 2 lines (I²C) to display the information. If you already have I²C devices in your project, this LCD module actually costs no more resources. Fantastic for an Arduino-based project.

A 16×2 dot matrix Character LCD Module display in STN Positive Yellow Green LCD Mode, Six O’clock viewing direction, Wide Temperature Range (Operating Temp: -20°C to 70°C, Storage Temp: -30°C to 80°C), and Yellow Green LED Backlight. It has a transflective polarizer, recommended for applications that will be used both indoor and outdoor. This product is assembled Chip On board with 1/16 Duty and a Controller IC AC780S or equivalent. The interface type is Serial – SPI. This is an ROHS Compliant product manufactured with ISO standards and procedures.
