Compatible with and can be directly inserted into all versions of raspberry PI motherboards (raspberry PI 1 generation B and Zero need additional HDMI cable)

After the installation of the LCD driver is completed, the system will restart automatically. If the LCD can be normally displayed and touched, the installation of the driver is successful

B. Ubuntu-18.04 system ssh connection may fail, the specific solution is shown in RaspberryPi Ubuntu-mate-18.04 ssh connection failure solution description

C. The retropie-rpi1_zero system cannot log in via SSH (no network port and wifi module). You need to copy the driver through the serial port. For details, see RaspberryPi Zero open serial instructions

2.8inch RPi LCD (A) and 3.2inch RPi LCD (B) are compatible with each other (the only differences are screen size and keys count), and can be mutually substituted in most cases.

Why the LCD doesn"t work with my Raspbian?To use the LCD with the Raspberry Pi official image, driver (SPI touch interface only) should be installed first. Please refer to the user manual.

However, for the first testing, you may want to use our image directly (if provided).Why the LCD still doesn"t work with the Waveshare provided image?Make sure the hardware connection is correct and connects fine.

The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.Which power supply should I use?It is recommended to use a 5V/3A power adapter for the Raspberry Pi other than USB connection, otherwise the Pi may failed to start up because the PC"s USB port might have not enough power.

CONS: low refresh rate & resolution, supports Raspberry Pi only, requires Raspberry Pi 40PIN GPIO (the SPI bus), poor compatibility with Raspberry Pi system.

PROS: high refresh rate, multiple resolution support, multiple devices support, leaves the Raspberry Pi 40PIN GPIO free, better compatibility with Raspberry Pi system.

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They"re usually some poor copies of our early hardware revisions, and comes with none support service.

※ Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule.

Connecting an LCD to your Raspberry Pi will spice up almost any project, but what if your pins are tied up with connections to other modules? No problem, just connect your LCD with I2C, it only uses two pins (well, four if you count the ground and power).

In this tutorial, I’ll show you everything you need to set up an LCD using I2C, but if you want to learn more about I2C and the details of how it works, check out our article Basics of the I2C Communication Protocol.

There are a couple ways to use I2C to connect an LCD to the Raspberry Pi. The simplest is to get an LCD with an I2C backpack. But the hardcore DIY way is to use a standard HD44780 LCD and connect it to the Pi via a chip called the PCF8574.

The PCF8574 converts the I2C signal sent from the Pi into a parallel signal that can be used by the LCD. Most I2C LCDs use the PCF8574 anyway. I’ll explain how to connect it both ways in a minute.

I’ll also show you how to program the LCD using Python, and provide examples for how to print and position the text, clear the screen, scroll text, print data from a sensor, print the date and time, and print the IP address of your Pi.

I2C (inter-integrated circuit) is also known as the two-wire interface since it only uses two wires to send and receive data. Actually it takes four if you count the Vcc and ground wires, but the power could always come from another source.

Connecting an LCD with an I2C backpack is pretty self-explanatory. Connect the SDA pin on the Pi to the SDA pin on the LCD, and the SCL pin on the Pi to the SCL pin on the LCD. The ground and Vcc pins will also need to be connected. Most LCDs can operate with 3.3V, but they’re meant to be run on 5V, so connect it to the 5V pin of the Pi if possible.

If you have an LCD without I2C and have a PCF8574 chip lying around, you can use it to connect your LCD with a little extra wiring. The PCF8574 is an 8 bit I/O expander which converts a parallel signal into I2C and vice-versa. The Raspberry Pi sends data to the PCF8574 via I2C. The PCF8574 then converts the I2C signal into a 4 bit parallel signal, which is relayed to the LCD.

Before we get into the programming, we need to make sure the I2C module is enabled on the Pi and install a couple tools that will make it easier to use I2C.

Now we need to install a program called I2C-tools, which will tell us the I2C address of the LCD when it’s connected to the Pi. So at the command prompt, enter sudo apt-get install i2c-tools.

Next we need to install SMBUS, which gives the Python library we’re going to use access to the I2C bus on the Pi. At the command prompt, enter sudo apt-get install python-smbus.

Now reboot the Pi and log in again. With your LCD connected, enter i2cdetect -y 1 at the command prompt. This will show you a table of addresses for each I2C device connected to your Pi:

We’ll be using Python to program the LCD, so if this is your first time writing/running a Python program, you may want to check out How to Write and Run a Python Program on the Raspberry Pi before proceeding.

There are a couple things you may need to change in the code above, depending on your set up. On line 19 there is a function that defines the port for the I2C bus (I2CBUS = 0). Older Raspberry Pi’s used port 0, but newer models use port 1. So depending on which RPi model you have, you might need to change this from 0 to 1.

The function mylcd.lcd_display_string() prints text to the screen and also lets you chose where to position it. The function is used as mylcd.lcd_display_string("TEXT TO PRINT", ROW, COLUMN). For example, the following code prints “Hello World!” to row 2, column 3:

On a 16×2 LCD, the rows are numbered 1 – 2, while the columns are numbered 0 – 15. So to print “Hello World!” at the first column of the top row, you would use mylcd.lcd_display_string("Hello World!", 1, 0).

You can create any pattern you want and print it to the display as a custom character. Each character is an array of 5 x 8 pixels. Up to 8 custom characters can be defined and stored in the LCD’s memory. This custom character generator will help you create the bit array needed to define the characters in the LCD memory.

The code below will display data from a DHT11 temperature and humidity sensor. Follow this tutorial for instructions on how to set up the DHT11 on the Raspberry Pi. The DHT11 signal pin is connected to BCM pin 4 (physical pin 7 of the RPi).

By inserting the variable from your sensor into the mylcd.lcd_display_string() function (line 22 in the code above) you can print the sensor data just like any other text string.

These programs are just basic examples of ways you can control text on your LCD. Try changing things around and combining the code to get some interesting effects. For example, you can make some fun animations by scrolling with custom characters. Don’t have enough screen space to output all of your sensor data? Just print and clear each reading for a couple seconds in a loop.

Monochrome lcd panel is low cost LCD screen, monochrome lcd display is the mainstream in custom lcd screen because its custom tooling fee is very cheap.Monochrome LCD display included standard graphic monochrome lcd display, character lcd module, monochrome segment lcd display, monochrome tft lcd module and custom lcd screen.The monochrome lcd screen structures have COG LCD (chip on lcd glass), COB (chip on board), COF (chip on film).

An seven segment lcd display is like the below picture, it can display numbers from 0 to 9 and several letters such as C, A, b E, L, and F by control some segments "on" and "off". it is the cheapest lcd display panel.

The segment lcd also could be in Icon lcd display, that is the display content are the custom segments based on customer"s application.each segment means one icon, we could design the icon on our application.

The familiar Characters lcd modules have 16x1, 16x2, 16x4 characters, 20x1, 20x2, 20x4 characters, and 40x2, 40x4 etc, characters lcd display module. An 16x2 lcd display means 16 characters x 2 lines character on the lcd. normally, one characters is made by 5x8 pixels, we could display numbers 1~9, and A~Z letters and most of characters on the 5x8 pixels per characters.

The standard graphic lcd resolution have 96x64、96x96、122x32、128x64、128x128、160x128、160x160、192x64、240x64、240x128、320x240 etc.we could display all the characters and image in the graphic lcd display. of course, the higher resolution lcd, the display effect of image would be better.

(What is lcd resolution: )Lcd resolution means how many pixels of lcd screen,128x64 lcd resolution means 128 column x 64 row pixels on the lcd screen, we also call it 128x64 lcd display. monochrome lcd resolution could be 320x240 (QVGA) or 480x240 maximum, tft lcd resolution could be VGA (640X480) or HD (1366x768, FHD(1920x1080) or 4k2k lcd resolution.

Yes, if you only need the low quantity monochrome lcd display for your project, you could choose Maclight standard monochrome lcd, Maclight have wide range standard Characters lcd and Graphic lcd module, including COB type and COG type for your choosing. please find the standard monochrome list in the end of article, welcome to contact Maclight at [email protected]

The tooling fee of monochrome lcd panel would be around 300~500 USD, if only the simple segment lcd panel, such as TN display mode, then tooling fee would be cheaper, but if the custom lcd screen is monochrome graphic lcd panel, such as STN display panel, the tooling fee would be little higher than TN lcd panel. because the tooling mask for stn lcd would be higher than TN lcd panel. but it is only the tooling fee for monochrome lcd panel.

If for custom monochrome lcd module that with IC chip on glass, we call it COG LCD module, the tooling fee would be more higher, because if for custom TN or STN lcd display panel, the tooling mask can be made by PI film, while for custom monochrome COG LCD module, the custom COG LCD tooling mask would be used the metal mask, the tooling fee would be more higher to around 1500~2000 USD.

Besides the custom lcds panel, for some custom lcd mode that in transmissive lcd or transflective lcd display mode, because lcd panel is passive display, instead of oled display, lcd panel can not emit light by itself, it have to use the backlight, the backlight tooling fee would be upper than 1000 USD or more, the more complicating structure on the backlight, the tooling fee would be higher. for saving the cost of tooling fee on lcd backlight, the simple structure would be cheaper.

The MOQ of custom lcd display for monochrome lcd is calculated based on the mother-glass of LCD panel, some person may ask, what is mother-glass of lcd panel? is it the mother of lcd panel? no, no,no..., it is just a joke, the mother-glass of lcd is the primary glass of lcd, we also call it ITO glass, because it have an ITO layer on the glass. the lcd panels are array on the mother glass in manufacturing lcd panel, and cutting it one by one after lcd cell production finished. the main mother glass sizes if 14"x16", as in lcd manufacturing, for stable running in the full-auto machine line, it is at least 50 set of 14"x16" for an production running, that is the smaller sizes of lcd, the bigger MOQ of lcd quantity is necessary.

1. Confirm the sizes what you would like to custom making? the custom mono lcd displays would be mainly less than 10", the custom sizes is up to the mother glass of lcd panels that is less than 14"x16". the custom mono lcd can be custom made the random sizes below 10".

If you would not like to custom lcd display, you could choose the standard lcd from the following list, it is no MOQ requirement for the standard lcd.

Monochrome lcd display have TN, STN LCD, monochrome tft lcd types. the monochrome lcd could be with or without backlight. even for monochrome lcd display, it have difference LCD colors for choosing, such as yellow-green mode, blue mode, gray mode, black-white mode, negative display mode and positive display available. the backlight color could be white, green, orange, yellow-green colors.
