1602 serial lcd module raspberry pi manufacturer

The principle of the LCD1602 liquid crystal display is to use the physical characteristics of the liquid crystal to control the display area by voltage, that is, the graphic can be displayed.

I2C uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL),pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems with other voltages are permitted. It can be operated as long as it supports the I2C development board.

Features: Easy to use; Less I/O ports are occupied; Support IIC Protocol; The I2C LCD1602 library is easy to get; With a potentiometer used to adjust backlight and contrast; Blue backlight; Power supply: 5v; I2C address is: 0x27.

How to connect it to Raspberry Pi and Ar-duino Compatibility Used for connecting Ar-duino and Raspberry pi and it can be used to display real time clock, temperature, humidity etc.

You can display the digital information or English sentense on the LCD screen by using Arduino, Raspberry Pi or other MCU which supports i2c protocol.

Features:[I2C] The 1602 LCD Module with I2C port greatly enriches the human-computer interaction functions, and when they are connected to the controller, the controller without too many external ports will not occupy multiple IOs, and will not restrict other functions of the controller. It has only two bidirectional data lines, a serial data line and a serial clock. How to wire: GNDGND; VCCVCC; SDAA4; SCLA5

[Widely Used] With the LCD shield, you can display whatever you want by programming the code for Arduino, Raspberry Pi board. Therefore, this is a perfect choice to make your project more interesting and vivid!

goods as described, fast dispatch. LCD display for use with Arduino. Purchased two, tested before use and found to be 100% apart from the one that I stupidly connected with reversed power connections! Yes! I broke it, so ordered a replacement. The PCB has screen printed connection information but some how l managed to mess this up. The displays appear well made and have a clear lcd with a decent viewing angle. Back light is also good.

Everyone love the 1602 character LCD, is cheap and works out of box! 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 quantity of 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.

I am currently having an issue with trying to connect my pi pico with the I2c adapter (LCM1602 of my 1602LCD display. I tried the official example from the raspberry pi github page (It is using the c/++ SDK for pi pico, but this was unsuccessful. I can compile/load the code, but nothing is displayed. I did a I2c bus scan and found out that the I2c address is indeed 0x27. So I know the pins and address are correct. I cant find a good datasheet that gives a overview of all commands for my type of adapter. They also do this weird thing in the code where the send a one byte command in six bytes ( void lcd_send_byte(uint8_t val, int mode) ). I am not very familiar with serial communication, so I dont know if this is normal. Can anybody maybe link a good reference datasheet for a LCM1602 I2c adapter or suggest what the best thing to do is from here?

LCD screens are useful and found in many parts of our life. At the train station, parking meter, vending machines communicating brief messages on how we interact with the machine they are connected to. LCD screens are a fun way to communicate information in Raspberry Pi Pico projects and other Raspberry Pi Projects. They have a big bright screen which can display text, numbers and characters across a 16 x 2 screen. The 16 refers to 16 characters across the screen, and the 2 represents the number of rows we have. We can get LCD screens with 20x2, 20x4 and many other configurations, but 16x2 is the most common.

In this tutorial, we will learn how to connect an LCD screen, an HD44780, to a Raspberry Pi Pico via the I2C interface using the attached I2C backpack, then we will install a MicroPython library via the Thonny editor and learn how to use it to write text to the display, control the cursor and the backlight.

2. Import four librariesof pre-written code. The first two are from the Machine library and they enable us to use I2C and GPIO pins. Next we import the sleep function from Time enabling us to pause the code. Finally we import the I2C library to interact with the LCD screen.from machine import I2C, Pin

3. Create an objecti2c to communicate with the LCD screen over the I2C protocol. Here we are using I2C channel 0, which maps SDA to GP0 and SCL to GP1.i2c = I2C(0, sda=Pin(0), scl=Pin(1), freq=400000)

5. Create an objectlcdto set up the I2C connection for the library. It tells the library what I2C pins we are using, set via the i2c object, the address of our screen, set via I2C_ADDRand finally it sets that we have a screen with two rows and 16 columns.lcd = I2cLcd(i2c, I2C_ADDR, 2, 16)

8. Write two lines of textto the screen. The first will print “I2C Address:” followed by the address stored inside the I2C_ADDR object. Then insert a new line character “\n” and then write another line saying “Tom’s Hardware" (or whatever you want it to say). Pause for two seconds to allow time to read the text.lcd.putstr("I2C Address:"+str(I2C_ADDR)+"\n")

9. Clear the screenbefore repeating the previous section of code, but this time we display the I2C address of the LCD display using its hex value. The PCF8574T chip used in the I2C backpack has two address, 0x20 and 0x27 and it is useful to know which it is using, especially if we are using multiple I2C devices as they may cause a clash on the bus.lcd.clear()

12. Turn the backlight back onand then hide the cursor. Sometimes, a flashing cursor can detract from the information we are trying to communicate.lcd.backlight_on()

13. Create a for loopthat will print the number 0 to 19 on the LCD screen. Note that there is a 0.4 second delay before we delete the value and replace it with the next. We have to delete the text as overwriting the text will make it look garbled.for i in range(20):

Save and runyour code. As with any Python script in Thonny, Click on File >> Saveand save the file to your Raspberry Pi Pico. We recommend calling it i2c_lcd_test.py. When ready, click on the Green play buttonto start the code and watch as the test runs on the screen.
