tft display for raspberry pi instructions made in china

There are plenty of small TFT LCD touch screens which mount on top of a Raspberry Pi out there, but ITEAD Studio"s "RPi 2.8 TFT Add-on V2.0" (snappy name, eh?) caught my eye because it has a pass-through for the Pi"s GPIO pins (out to the side, because you wouldn"t want to mount another board on top of a display...) and brings the I2C and serial ports out to "Grove"-style connectors - so, it"s not only a nice display, it"s maker-friendly.

Only one problem - like a lot of Chinese suppliers, ITEAD don"t exactly hold your hand when it comes to documentation. Their wiki page includes a schematic so the detail is there, and they have a pointer to notro"s wonderful framebuffer drivers - but it"s not at all clear after that exactly which drivers apply and how to get it running. And although there are plenty of LCD touch screen tutorials out there, they"re written for other displays (including V1 of this display, which has different connections) and it"s not obvious what has to be changed, where, to get this display up and running. And quite a few tutorials are outdated, now that we live in device tree land....

So I"ve written a detailed, but hopefully clear, guide to getting this LCD touch screen display working: http://www.gooligum.com.au/blog-section/TFT-28-setup

To interface any random piece of hardware with a raspberry pi you need to know a few things 1) voltage limits, 2) pinout (you can kill any device by swapping GND and Vcc, 3) the interface (SPI, I2C, 1-wire, USB, 8-bit) and 4) the bytes you need to send to the device to control it.

The makers of reliable, well documented devices publish all of that information in a document called a datasheet. It tells you what you need to know to a) wire it to your RPi and b) drive it from software.

For something random bought from some unknown Chinese vendor on eBay you may not get that info. For something bought from Adafruit or CPC/Farnell/Element14 you are 100% guaranteed to get the datasheet, you may even get pictorial wiring diagrams and software code samples to drive the devices they"re selling.

There"s a difference in cost of a few dollars more for a supported device, but when you think of how much your time is worth those few extra dollars pay for themselves.

With a random device from China you have four options a) cut your losses, b) return it, c) search the internet for some bright spark who has spent lots of time investigating the device and documenting it or d) spend lots of time investigating and documenting it yourself (that may need specialist kit like a logic analyser).

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.

2) Connect the TF card to the PC, open the Win32DiskImager software, select the system image downloaded in step 1 and click‘Write’ to write the system image. ( How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details)

3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)

This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.

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).

BONUS: I made a quick start guide for this tutorial that you can download and go back to later if you can’t set this up right now. It covers all of the steps, diagrams, and code you need to get started.

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.

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.

Key information: This device"s controller is an ILI9486, which is compatible with ILI9481. The driver for ILI9481 was already in my Raspberry Pi. Here"s what I did to make it work:

I don"t care about the touch-screen, so I didn"t set it up. All I need this is to show me the IP address of the Raspberry Pi so I can connect through SSH. (This is an issue you may encounter only if you find your RPi connecting to WiFi where you cannot control the IP address assignments and with ridiculously short lease times.)

Every model of Raspberry Pi needs some form of output and typically this takes the form of a screen. You can forgo a monitor and set up a headless Raspberry Pi, but having a screen is better where possible because you don’t need a network connection and using VNC for remote viewing makes watching videos or the camera feed slow and tedious.

Over the years there have been many projects and hacks to include a portable screen. From Motorola Atrix Lapdocks, to CrowPi2 there are many different ways to have a portable Pi. But after reading a Reddit thread, we wondered if we could make our own portable Raspberry Pi setup by using an Android tablet (or phone) as the screen.

This project will see the HDMI output from our Raspberry Pi converted into a USB “webcam” input via a USB HDMI video capture device, which sells for around $15. Using a free app we “trick” the tablet into displaying the Raspberry Pi desktop. All of this kit will fit easily into a bag for easy transport and it can be used with a USB power bank.

1. Insert a micro HDMI lead into the first micro HDMI port of the Raspberry Pi 4 / Raspberry Pi 400. Other models of Raspberry Pi will require either a mini (Raspberry Pi Zero) or full size HDMI lead.

4. On your android device, open the Google Play store andinstall theUSB Camera Standard. This free app will be used to see the Raspberry Pi desktop on our device.

By default the resolution is set to 1920 x 1080 and it may be a little uncomfortable to see. A quick fix is to enable pixel doubling, effectively giving us the same screen resolution, but doubling the size of text and UI elements.

VNC is great and it works really well, but there are some limitations with the Raspberry Pi. The biggest of which is any video which is directly rendered to the screen, bypassing the X server, cannot be seen by VNC and this includes any output from the Raspberry Pi Cameras.

This screen won’t work when you just plug it into your Raspberry Pi, you’ll need to edit a few configuration on boot. Touchscreen I have not tested but included some ideas on how to make it work

To begin with the board itself, it’s okay. The screen display I received was a bit damaged, there were some clearly visible and wide scratches and one component was soldered pretty sideways, but it worked and that was within my expectations for a $50 screen.

Make sure your power supply is rated at a high current. A 500 mA 5 volt supply will not cut it to both power the Pi and the screen. I’ve tested this with a 2A power supply and this worked great. You can plug the USB from the screen into the Pi itself to supply current to it.

I haven’t tried this yet but by the looks of it the board is a clone of the waveshares board. They seemingly offer better support for their hardware, and I will gladly point you in the right direction as their instructions seem to be quite clear.

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.

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.
