The Sitronix ST7789 is a driver chip for small color IPS LCD displays that supports SPI interfaces. This example uses a 2-inch color LDC display manufactured by Waveshare with a retail price of approximately $13 or $14.75 on Amazon Prime.

Note: The ST7789 uses a SPI interfaces but not a true standard SPI protocol. The device only uses MOSI (DIN) to send data from master to slave for LCD display. Only four wires are needed to connect from the Pico to the device.

For most LCD controllers, the communication method of the controller can be configured, they are usually using 8080 parallel interface, 3-line SPI, 4-line SPI, and other communication methods. This LCD uses a 4-line SPI interface for reducing GPIO and fast speed.LCD

This is a LCD display HAT for Raspberry Pi, 1.44inch diagonal, 128x128 pixels, with embedded controller, communicating via SPI interface. It also comes with three push button and a joystick, a good option as user interface panel for your Raspberry Pi Zero :)

The MakePython ESP32 WiFi Color LCD Display WROOM is programmed with MicroPython by default, users can begin the MicroPython development by getting them on hand.

This MakePython ESP32 Color LCD is the color LCD version of the MakePython ESP32. The only difference is that this version uses a colorful 1.3 inch LCD ST7789, which makes the boards suitable for applications that need a colorful display.

The SparkFun SerLCD is an AVR-based, serial enabled LCD that provides a simple and cost effective solution for adding a 16x2 RGB on Black Liquid Crystal Display into your project. We"ve seriously overhauled the PCB design on the back of the screen by including an ATmega328P that handles all of the screen control, meaning a backpack is no longer needed! This display can now communicate in three different ways: serial, I2C, and SPI. This comes equipped with a Qwiic connector, bringing serial LCDs into the Qwiic ecosystem. This simplifies the number of wires needed and allows your project to display all kinds of text and numbers.

The on-board ATmega328P AVR microcontroller utilizes 11.0592 MHz crystal for greater communication accuracy with adjustable baud rates of 1200 through 1000000 but is default set at 9600. The firmware for this SerLCD is fully opensource and allows for any customizations you may need.

Note: Since the SerLCD is a 3.3V device, please make sure you convert to 3.3V logic depending on your chosen microcontroller or single board computer. Otherwise, you may risk damaging your board.

Drivers and code for two very low cost LCD displays with instructions on how to setup each with python on a Raspberry Pi. This github repo has plenty of demo files I"ve collected from others or written myself to display some possibilities.

We need to do a few things before you can begin running demo python scripts to display things on the LCD screen. Just follow the steps and you should be fine. If you are using the root account, you can ignore the sudo command. You only need to do these steps once.

We sourced this vibrant LCD display to use on Pico Explorer Base and we"ve become rather fond of it. We"ve given it the full Breakout Garden treatment and now it"s super-easy to incorporate into other Raspberry Pi or Raspberry Pi Pico projects. The screen is around 40% bigger (by area) than the one on our 1.3" square breakout, giving you plenty of room to fill with detailed graphs or lots of data from sensors. Its 1:1 aspect ratio means it would also be good for displaying square images (like album art or Instagram photos), or perhaps even for using as the screen on a mini handheld games console?

Like our other LCD breakouts, it"s an IPS display so has great viewing angles and it"s super-crisp and bright. It"s driven by SPI and you should be able to run it at up to ~50FPS, although we"ve found that anywhere from 10FPS looks good for most uses.

This breakout uses the same ST7789 library as our square and round LCDs. The library makes it straightforward to display images, text or graphics, and even display animated GIFs!

Our Python library is set up to use SPI 0 by default on the Pi (BCM 7 for CS, BCM 11 for SCK, and BCM 10 for MOSI), BCM 9 for DC, and BCM 19 for the backlight.

Display HAT Mini features a bright 18-bit capable 320x240 pixel display with vibrant colours and formidable IPS viewing angles, connected via SPI. It"s got four tactile buttons for interacting with your Pi with your digits and a RGB LED for notifications. We"ve also squeezed in a QwST connector (Qwiic / STEMMA QT) and a Breakout Garden header so it"s a doddle to connect up different kinds of breakouts.

It will work with any model of Pi with a 40 pin header, but we think it goes with the Raspberry Pi Zero particularly well - we"ve included a pair of standoffs so you can use to bolt HAT and Pi together to make a sturdy little unit. To accommodate the screen Display HAT Mini is a bit bigger than a standard mini HAT or pHAT - it"s around 5mm taller than a Pi Zero (so a Mini HAT XL or a Mini HAT Pro, if you will).

Display HAT Mini lets you turn a Raspberry Pi into a convenient IoT control panel, a tiny photo frame, digital art display or gif-box, or a desktop display for news headlines, tweets, or other info from online APIs. This screen is a handy 3:2 ratio, useful for retro gaming purposes!

To get started, follow the installation instructions in the Display HAT Mini library. This library contains some examples of how to use the screen, buttons and LED with Pygame. You can also find examples for this screen in our ST7789 Python library, these show you how to write and draw on the screen using PIL to display shapes, text and gifs.

We"ve also been having fun with fbcp-ili9341 - a high level framebuffer driver for SPI-based LCD displays. The Raspberry Pi OS desktop is a leeetle small on a 2.0" screen, but this might be a good option if you"re doing something like building your own custom retro console.

If you have a Breakout Garden breakout without a Qw/ST connector, you can either pop one of these adaptors on the end of your cable, or you can plug a Breakout Extender into the header at the other end of Display HAT Mini (you can find it next to your Pi"s SD card slot).

Please note that because of Display HAT Mini"s extra size, it will overhang adjacent slots on expansion boards like pHAT Stack, Black HAT Hacker, HAT Hacker HAT and Flat HAT Hacker. No shame - every HAT is valid, every HAT is beautiful.

There"s two ways you can use the 1.3" 240x240 display.Be aware that you can only choose to do one way at a time. If you choose the hard way, it will install the kernel driver, which will prevent you from doing it the easy way.

The easy way is to use "pure Python 3" and Pillow library to draw to the display from within Python. This is great for showing text, stats, images etc that you design yourself. If you want to do that, skip this page and go to the Python install/usage page

The hard way is to install a kernel module to add support for the TFT display that will make the console appear on the display. This is cute because you can have any program print text or draw to the framebuffer (or, say, with pygame) and Linux will take care of displaying it for you. If you don"t need the console or direct framebuffer access, please consider using the "pure Python" technique instead as it is not as delicate.

Hey everyone, in this tutorial we are going to interface a Liquid Crystal Display (LCD) module with the Raspberry Pi Pico using Micropython. By the end of this tutorial, you will be able to display strings, characters on the LCD using Micropython. Before beginning this tutorial, I"m presuming that you"ve already followed our tutorial series on Raspberry Pi Pico. Previously we have worked with an OLED display and we have seen the I2C and ADC on the Raspberry Pi Pico. Now, let’s see how to interface an LCD display module with the pico board.

The 16x2 LCD gets its name from the fact that it contains 16 columns and 2 rows. As a result, it will contain a total of (16x2=32) 32 characters, with each character consisting of 5x8 Pixel Dots. The image below depicts a single character with all of its pixels.

Each character has a size of (5x8=40) 40 pixels, giving us a total of (32x40) 1280 pixels for 32 characters. Additionally, the LCD instructions should be told where the pixels are located. As a result, controlling everything using a microcontroller will be challenging. So, an interface IC, such as the HD44780, is used on the backside of the LCD Module. More information is available in the HD44780 Datasheet.

This IC"s job is to take commands and data from the MCU and process them so that relevant information may be shown on the LCD screen. Without a backlight, the LCD"s working voltage ranges from 4.7 to 5.3 volts and its current usage is 1mA. It is capable of working in both 8-bit and 4-bit modes. These LCDs come with a green or blue backlight and may also show any characters created by the user.

The LCD display will have 16 Pins. ThePinout and Pin Description of the 16x2 LCD Module is mentioned in the table below. You can refer to this article on 16x2 LCD Display Module on our website for more details about the LCD pinouts.

The following circuit diagram is representing the connection of the LCD to the Raspberry Pi Pico. I have used a potentiometer to control the brightness of the LCD display. The 4-bit data pins (i.e. D4 to D7) are connected to the GPIOs 18,19,20,21 respectively. The Rs pin of the LCD is connected to the GPIO 16 and the E pin is connected to the GPIO 17. The output of the potentiometer is connected to the V0 pin of the LCD and the VBUS pin is connected to the input terminal of the potentiometer. This VBUS pin of the pico is used to power the LCD via VDD pin of the LCD. Pin number 15 of the LCD is connected to the VDD pin of the LCD to provide the power supply of 5V and Pin number 16 of the LCD is connected to the Ground pin followed by the RW pin of the LCD.

To program the LCD with Raspberry Pi Pico using Micropython, you need to download the respective library and code files from our GITHUB repository of the Raspberry Pi Pico Tutorial Series. When you open the “codes”, you will get two python files named “lcd_pico.py” and “main.py”. The “lcd_pico” can be used as a library to program the LCD display with Raspberry Pi Pico using Micropython. In the “main.py” file I have used some functions from the “lcd_pico.py” file to display some strings on the LCD. Let’s discuss both python files one by one.

In the “lcd_pico.py” file, we have imported two libraries “machine.py” and the “utime.py”. The machine library contains the built-in functions to define the Pins, GPIOs, etc. The “utime” library is used to provide the delay in the code. Then I have defined the GPIO pins for the 4-bit data pins of the LCD and the RS and E pin of the LCD. The “machine.Pin(16,machine.Pin.OUT)” is used to set the GPIO21 as OUTPUT and assign this in the “rs” variable. Similarly, the GPIOs 17 to 21 are set as OUTPUT pins and assigned to the “e”, “d4”, “d5”, “d6”, and “d7” variables respectively.

The “setCursor(line,pos)” function below is used to set the position of the cursor. We need to pass two parameters “line” and “pos”. In my case, I am using the 16x2 LCD which has 2 lines to set the cursor. And the “pos” is used to set the position where we want to print the data.

TheclearScreen() function is used to clear the display screen and the setupLCD() function is used to initialized the LCD. We need to use the setupLCD() function at the starting of our main code. The displayString() is used to display any String data. This function takes three parameters that are “row”, “col” and the “input_string”. The “row” and “col” are used to set the cursor position and the “input_string” is used to pass the string that needs to be print on the LCD.

In the main.py file, I have imported the “lcd_pico” library and then I have called the “setupLCD()” function. Then I used the “displayString()” function to print the following strings. In this function, I have passed the “row” and “col” to set the cursor position and then I have passed the strings to be displayed on the LCD. The longDelay() function is used to provide the delay in microseconds.

In the while loop below I have used the displayString() to display the “CIRCUIT DIGEST” with 1.5 seconds of interval. The clearScreen() is used to clear the display screen in every 1.5 Seconds.

Now, in the Thonny IDE, open the “main.py” and “lcd_pico.py” files. To begin, save the “lcd_pico.py” file on the Pico board by pressing the “ctrl+shift+s” keys on your keyboard. Before saving the files, make sure your Pico board is connected to your laptop. When you save the code, a popup window will appear, as shown in the image below. You must first select the Raspberry Pi Pico, then name the file “lcd_pico.py”andsave it. Then repeat the process for the“main.py” file. This procedure enables you to run the program when the Pico is turned on.

When you upload and run the code on the pico board, you will see the output similar to the images below. The first image is showing the “WELCOME” string in the first row of the LCD and “TO” string in the second row of the LCD. Then after 4 seconds of delay, it is displaying the “CIRCUIT” string in the 1st line of the LCD and “DIGEST” string in the 2nd line of the LCD.
