Step 3: insert the Micro SD card into the Raspberry Pi, connect the HDMI cable to the Raspberry Pi and the LCD, connect the USB cable to any of the 4 USB ports of the Raspberry Pi, connect the other end of the USB cable to the USB port of the LCD, and then give the Raspberry Pi Power-on. If the display and touch are normal, the drive is successful (please use the 2A power supply).
2. Connect one end of the MicroUSB cable to the USB Touch interface of the LCD (any of the two MicroUSBs) and the other end to the USB port of the computer.
3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.
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.
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.
The UCTRONICS 3.5 Inch touch screen is the same size as the standard Raspberry Pi model B/B+, and well-mates with the Raspberry Pi boards. With a tiny size, vivid image, and responsive touchscreen, it is definitely ideal for portable devices and multimedia projects. It is a great replacement for a heavy and bulky HDMI monitor, keyboard, and mouse
Step1: Align the pin 1 of the edge connector between the LCD display and Raspberry pi board, connect the pin 1,2,3,4 then pin 19,20,21,22,23,24,25,26.
Attention: If you use this display without a Pi, the touch function is not available because the touch function of this display just supports the Raspbian system. Meanwhile, an extra HDMI cable also is required for the video transmission.
The 3.5 inch RPI lcd display TFT Capacitive Touch Screen is a display module can be applied to Raspberry pi 3 B+ Pi Zero etc. It can be used as raspberry pi x window display terminals.
The RPI LCD Display TFT Capacity Touch Screen Modules used 28 pins out of raspberry pi 40 pin. When installing the module attention to align the first leg of the raspberry pi and LCD module.

Raspberry Pi is a Palm Size computer that comes in very handy when prototyping stuff that requires high computational power. It is being extensively used for IOT hardware development and robotics application and much more memory hunger applications. In most of the projects involving the Pi it would be extremely useful if the Pi had a display through which we can monitor the vitals of our project.
The pi itself has a HDMI output which can be directly connected to a Monitor, but in projects where space is a constrain we need smaller displays. So in this tutorial we will learn how we can interface the popular 3.5 inch Touch Screen TFT LCD screen from waveshare with Raspberry pi. At the end of this tutorial you will have a fully functional LCD display with touch screen on top of your Pi ready to be used for your future projects.
It is assumed that your Raspberry Pi is already flashed with an operating system and is able to connect to the internet. If not, follow the Getting started with Raspberry Pi tutorial before proceeding.
It is also assumed that you have access to the terminal window of your raspberry pi. In this tutorial we will be using Putty in SSH mode to connect to the Raspberry Pi. You can use any method but you should somehow be able to have access to your Pi’s terminal window.
Connecting your 3.5” TFT LCD screen with Raspberry pi is a cake walk. The LCD has a strip of female header pins which will fit snug into the male header pins. You just have to align the pins and press the LCD on top of the Pi to make the connection. Once fixed properly you Pi and LCD will look something like this below. Note that I have used a casing for my Pi so ignore the white box.
For people who are curious to know what these pins are! It is used to establish a SPI communication between the Raspberry Pi and LCD and also to power the LCD from the 5V and 3.3V pin of the raspberry Pi. Apart from that it also has some pins dedicated for the touch screen to work. Totally there are 26 pins, the symbol and description of the pins are shown below
Now, after connecting the LCD to PI, power the PI and you will see a blank white screen on the LCD. This is because there are no drivers installed on our PI to use the connected LCD. So let us open the terminal window of Pi and start making the necessary changes. Again, I am using putty to connect to my Pi you can use your convenient method.
Step 2: Navigate to Boot Options -> Desktop/CLI and select option B4 Desktop Autologin Desktop GUI, automatically logged in as ‘pi’ user as highlighted in below image. This will make the PI to login automatically from next boot without the user entering the password.
Step 3: Now again navigate to interfacing options and enable SPI as show in the image below. We have to enable the SPI interface because as we discussed the LCD and PI communicates through SPI protocol
Step 4: Click on this waveshare driver link to download the driver as a ZIP file. Then move the ZIP file to you PI OS. I used Filezilla to do this, but you can also use a pen drive and simple copy paste work. Mine was placed in the path /home/pi.
Step 7: Now use the below command to restart your Pi. This will automatically end the terminal window. When the PI restarts you should notice the LCD display also showing the boot information and finally the desktop will appear as shown below.
You can also watch the video below to check how the LCD is connected and how it responds to touch. I am pretty much satisfied with its default accuracy so I am not going to do any calibration. But if you are interested you can view the official wiki page from waveshare where they discuss how to calibrate and enable camera view on the LCD screen.
Hope you understood the tutorial and were successful in interfacing your LCD with PI and got it working. If otherwise state your problem in the comment section below or use the forums for more technical quires.
In this tutorial, we are going to interface a 3.5-inch TFT display with Raspberry Pi Zero Wdevelopment board. Although Raspberry pi zero itself has an HDMI output that can be directly connected to a Monitor, but in projects where space is a constrain, we need smaller displays. This TFT touch screen display can be easily interfaced to the Raspberry Pi to display the system console, movies, and images, as well as control a relay board and other devices at your fingertips. We’ve used software like MobaXterm or putty to connect to the PC remotely in past tutorials. Here, we are going to use MobaXterm software to install the required drivers for interfacing TFT display with Raspberry Pi Zero W.
This TFT LCD display has a 3.5-inch resistive touch screen display and is compatible with any hardware of the Raspberry Pi family. This 3.5" TFT display has 480x320 pixels with a 16-bit resolution and resistive touch option. It can fit directly on top of the Raspberry Pi Zero W board and gets powered from the Vcc pin, the display communicates through SPI protocol with the Pi. Additionally, you can also use the HDMI port on the Pi to connect it to another display as well. It is designed for Raspberry Pi Zero/Pi 2 /Pi 3 Model B / B+ and can also be used on other hardware platforms which have SPI interfaces. The highlights of this display module is that it supports plug and play without rebooting the Pi and the SPI speed runs as fast as 32MHz to support games and videos.
There are 26 pins in TFT RPi LCD display. It"s used to establish SPI communication between the Raspberry Pi and the LCD, as well as to power the LCD from the Raspberry Pi"s 5V and 3.3V pins. The description of pins is shown below.
It is very easy to connect Raspberry Pi Zero W with a 3.5” TFT LCD display. There are 40 pins on the Raspberry Pi Zero W, but only 26 pins on the LCD, so make sure you connect the pins to your Pi correctly. A strip of female header pins on the LCD will fit snugly into the male header pins. To establish the connection, simply align the pins and press the LCD on top of the Raspberry Pi zero W. When everything is in place, your Pi and LCD should look like the one given below.
After you"ve connected the LCD to the Raspberry Pi Zero W and power on it, you"ll see a blank white screen on the LCD which is due to the fact that no drivers for the linked LCD have been installed on the Pi. So, open the Pi"s terminal window and start making the necessary adjustments. Here, we are going to use MobaXterm software for connecting Raspberry Pi Zero W but you can use PuTTY or any software which is most comfortable for you.
It"s expected that your Raspberry Pi already has an operating system installed and can connect to the internet. If it is not then you can follow our previous tutorial Getting Started with the RASPBERRY PI ZERO W – Headless Setup without Monitor. It"s also assumed that you have access to your Raspberry Pi"s terminal window. In this tutorial, we are going to use MobXterm in SSH mode to connect it with Raspberry Pi Zero W.
Step-2: In this step, we are going to enable SPI connection for Raspberry Pi Zero W. To enable SPI communication, select ‘Interface options’, and then select ‘SPI option’. Then click on "yes" to enable SPI interfacing.
Step-3: Now as we have enabled the SPI interfacing, in this step, we are going to install touch driver in our Raspberry Pi Zero W. You can install the touch drivers using the below command:
Step-4: After installing the touch driver use the below commands to proceed with further setup, here we are using chmod command to change the access mode of the file.
Step-5: Now, restart your Raspberry Pi Zero W. When the Raspberry Pi Zero W restarts, you will see the boot information on the LCD display before the desktop appears, as shown below.
I would like to add one thing at the end of this tutorial that while doing this interfacing, I faced a problem related to OS. TFT display interfacing with Raspberry Pi Zero W was not working on Raspberry Pi OS LiteandRaspberry Pi OS with desktopbut when I used the Raspberry Pi OS with desktop and recommended software then TFT display interfacing with Raspberry Pi Zero W worked as expected.
This is how you can interface Raspberry Pi Zero W with a 3.5 inch TFT Raspberry Pi display. In our next tutorials, we are going to interface different sensors with Raspberry Pi Zero and you will see some amazing DIY projects using Raspberry Pi Zero W. I Hope you"ve enjoyed the project and learned something useful. If you have any questions, please leave them in the comment section below or use our forum to start a discussion on the same.
Is this not the cutest, little display for the Raspberry Pi? It features a 3.5" display with 480x320 16-bit color pixels and a resistive touch overlay so it is slightly larger than the Raspberry Pi board, which is perfect to cover it. The plate uses a high-speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video, etc. Best of all it plugs right on top nicely covering the Raspberry Pi board. Single power from Raspberry Pi is sufficient to operate the screen. As it uses the SPI and Power pin from Raspberry Pi"s GPIO, it is nicely stacked on the RPi board. We also carry the perfect case/enclosure for Raspberry Pi 3B/3B+ and also 4B to be used with this LCD.
The TFT isn"t "plug & play" with the Raspberry, a patch has to be applied to the kernel to be able to interface via SPI with the ST7735R controller chip on the TFT. Once working, the display will act as a framebuffer device.
As it takes over three hours to compile the kernel on the PI, I will show how to cross compile from another Linux PC. In my case, it is Ubuntu 12.10 running within VMWare on a Windows 7 Quad core PC. Kernel compile time is 15 mins.
-Copy config from the Raspberry Pi to the Ubuntu box using SCP. Replace "raspberrypi" below with the IP address of your Raspberry Pi if hostname lookup fails.
If you are planning on displaying the console on the TFT, then enabling these options in .config will allow you to change the font size and rotate the display later on.
To enable parallel processing for a faster compile. If you have a dual core processor add -j 3 to the end of the command below. If you have quad core, add -j 6
The last step below is to SCP the files from from Ubuntu to the Raspberry Pi. If you have trouble SCPing into your Ubuntu box you may need to install open SSH on Ubuntu with sudo apt-get install openssh-server. This step also copies the files from my home folder "mark"... yours would be different.
If you build the st7735 driver pair as built-in, add these options to the end of the line in /boot/cmdline.txt. This will display the console on the TFT.
STONE Technologies is a specialized manufacturer of intelligent TFT LCD modules for HMI. Depending on the application, STONE Technologies offers industrial, advanced and residential smart TFT LCD modules in different sizes.
In this project, I will control LEDs with the help of STONE HMI display and Raspberry Pi GUI design. command data is sent to Raspberry-pi via Display, which is sent in frames, as Display sends data in frames and receives it in frames of HEX code. If you want to understand the data frames and how they work, I am using the STWI056WT-01 model in this project? You can download the datasheet from here.
Now first connect Raspberry-Pi through VNC server or you can connect directly through display as per your convenience. Then there are two codes which are given below. The first one is for testing the all buttons which we have created and second one the Whole code with I/O setup and it has logic.
Here the purpose of testing code is to check all buttons so for this you need to connect first USB-0 of Raspberry-Pi to you Display TTL connector and then copy this code in Thonnyof Raspberry-Pi as given in below image and then click on run button to test it.
GPIO.setup(red_led,GPIO.OUT) GPIO.setup(green_led,GPIO.OUT) GPIO.setup(blue_led,GPIO.OUT) GPIO.setup(led1,GPIO.OUT) GPIO.setup(led2,GPIO.OUT) GPIO.output(red_led,GPIO.LOW) GPIO.output(green_led,GPIO.LOW) GPIO.output(blue_led,GPIO.LOW) GPIO.output(led1,GPIO.LOW) GPIO.output(led2,GPIO.LOW) ######################
Now that we have understood the logic behind the code, let’s run the second code in Raspberry-Pi, which is the complete code, but before making the circuit connections as shown in the circuit diagram below.
