lcd module i2c factory

I2C_LCD is an easy-to-use display module, It can make display easier. Using it can reduce the difficulty of make, so that makers can focus on the core of the work.

We developed the Arduino library for I2C_LCD, user just need a few lines of the code can achieve complex graphics and text display features. It can replace the serial monitor of Arduino in some place, you can get running informations without a computer.

More than that, we also develop the dedicated picture data convert software (bitmap converter)now is available to support PC platform of windows, Linux, Mac OS. Through the bitmap convert software you can get your favorite picture displayed on I2C_LCD, without the need for complex programming.

The CFA533-***-KC series is a 16x2 I2C LCD with keypad. The I2C interface allows you to use just two lines (SDA & SCL) to have bi-directional communication with the I2C LCD. Other devices can also share those two I2C control lines with the LCD. Only 4 wires are needed to connect this I2C LCD: power, ground, SDA (I2C Serial DAta) and SCL (I2C Serial CLock).

The CFA533 can run on 3.3v to 5.0v directly, with no changes needed, so you do not need to do any level translation between your embedded processor and the I2C LCD. Simply power the CFA533 from the same supply as your processor and the I2C signal levels will match up.

Using only one address on your I2C bus, you can add all the elements that you need for your front panel. The CFA533 I2C LCD can also read up to 32 DS18B20 digital temperature sensors, giving you an easy way to integrate temperature sensing over the I2C bus. No additional firmware or pins are needed on the host system.

This CFA533-TFH variant features crisp dark letters against a white, backlit background. The keypad has a matching white LED backlight. Since the LCD is a backlit positive FSTN, the CFA533-TFH I2C LCD is readable in direct sunlight, as well as complete darkness.

As the maker movement has increasingly grown, we’d like to share the way to use Arduino and begin with controlling the LCD module. Yes, we’d like to start from LCD module instead of installation since makers can find lots of related information from the Internet. So we’ll have less basic introduction here.

After reading this article and manipulating, you will have the basic understanding of I2C bus and LCD, and learn the way to connect modules with Arduino, use basic program to control your LCD module, and think about the applications. The advanced control techniques will be explained in the future articles.

I2C Bus enables 2 devices to communicate with each other in a stable, high-speed, bidirectional way and with the least I/O pins. I2C Bus utilizes 2 lines to communicate, Serial Data Line (SDA) and Serial Clock Line (SCL), so that the protocol I2C uses is also called “bidirectional” protocol.

What’s more special is I2C Bus allows multiple devices to share the common communication lines. Thus, I2C Bus could control the communication function.

Here we use Arduino as the main board to control; pin A4 and A5 on the board are SDA and SCL pins respectively. To use I2C function, you would need to use Wire Library, which is the built-in library of Arduino IDE.

LCD is the abbreviation of liquid-crystal display; it’s a commonly-used display device and utilized everywhere in our daily life, from watches, calculators, TV to bulletin board.

This LCD module is the basic one and the most commonly-used character display; The voltage is 5V. The voltage level Arduino I/O Port uses is 5V so that we choose the LCD module. Besides, the LCD module can display 16 characters per line and there are 2 such lines. Also, the module uses I2C protocol. Thus, there are 4 pins on the module, including Vcc, GND, SDA, and SCL.

It is also easy to connect the wires. Firstly, you need to connect pin Vcc of the module to Arduino pin 5V, connect pin GND to Arduino pin GND, and connect pin SDA to Arduino pin A4. Lastly, connect pin SCL to Arduino pin A5 to complete the wiring.

Before introducing the sample, we’d like you to download the 3rd party libraries of I2C_LCD first. You can download the files here, decompress, and install. In this sample, the version we use is NewliquidCrystal_1.3.4. The followings are the codes we use for this sample.

Then, at the setting of initialization, LCD backlight will be controlled to blink 3 times. The first line will display “ICshop&MakerPRO” for one second, and the second line will display “Hello, Maker!” for 8 seconds. Then all the display will be cleared.

Hope all of you successfully complete the I2C_1602_LCD module display with the description mentioned above. If you failed, please check the wiring or you bought a defective device.

So next, you could think of if you can use the module to make a clock or environment sensors. You might have tons of ideas now! Why don’t you connect a LCD module in your next project?

This module realizes a fast I2C interface with the familiar LCD displays (16x02, 16x04 and 20x04), which makes the control of these displays much easier and more economical with I / O pins.

Because this module has 8 options for the address (0X20-0X27), it is possible to control 8 of these interface modules simultaneously with only 2 connections. By means of the built-in potentiometer on this module it is possible to adjust the backlight and contrast of the LCD.

Winstar WO1602G is 16 characters x 2 lines COG Character LCD module with metal pin connection. This display is built in with ST7032I controller IC and it supports I2C interface. This series of module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃.

A regular LCD requires a lot of wires (parallel interface) to be connected with a Microcontroller.The Serial LCD  backpack built on PCF8574 IC uses the I2C bus to convert  the parallel interface to a serial one.This needs only2 wires SDA & SCL , apart from the power connections.

The blue preset is to adjust the contrast of the LCD. The black jumper on the left is to enable the Backlight of LCD. The I2C device has a HEX address by which a microcontroller can communicate with it.This is set by the 3 bits A0,A1 ,A2 .If no jumper is present , it is HIGH &  a jumper means LOW. By default all the 3 jumpers are open . ie., A0,A1 A2 all are 1s.

The I2C bus has 2 bidirectional active wires SDA & SCL .They are joined to positive supply through a pull up resistor of 4k7.When the bus is  idle both lines are pulled high.

lcd.setBacklightPin(HIGH);  makes the P3 pin go High, which turns on the NPN transistor.This provides GND to the LED pin of LCD As the other LED pin is already connected to Vcc through the jumper , the LCD backlight glows.

Hello friends welcome back to Techno-E-solution, In previous video we see how to interface LCD 16×2 to Arduino uno, but there are very complicated circuits, so in this tutorial, I"ll show you how to reduce circuitry by using I2C module which is very compact & easy to connection. Simply connect I2C module with LCD parallel & connect I2C modules 4 pins to Arduino. I2C module has 4 output pins which contains VCC, GND,SDA, SCL where 5V supply gives to I2C module through VCC & GND to GND of Arduino. SDA is a data pin & SCL is clock pin of I2C module. To interface LCD and I2C with Arduino we need Liquid Crystal I2C Library in Arduino IDE software.
