At this point your Octoprint should be loaded but your mouse and touch screen will probably be moving backwards. In the newer (Jessi, Buster) versions of Raspbian they change input control from evdev to libinput. You need to install evdev or it will ignore you 40-libinput.conf configurations.

Understanding that many people have problems configuring their Kuman TFT display on the Raspberry Pi together with RetroPie, I have decided to make this step-by-step of how to install the Kuman TFT 3.5" display which you can connect directly to the GPIO ports of the Raspberry Pi and run your applications. A lot of people have been buying this Kuman display from Amazon and other online markets for its economical price but it is not an easy display to install for certain applications, compared to other displays that come with integrated HDMI ports that will surely be a lot easier to manipulate and start working.

I advise you to buy a GPIO cable or a ribbon cable to connect the display to the Raspberry Pi, because sometimes (and it happened to me) at the time of manipulating the display and fitting it on the pins of the Raspberry, the screen being so the thin can be broken easily.

Verify that you have RetroPie burn on your SD Card, if you have not already done so, click on the following link, install it and come back here to continue the steps.

Next, copy the following code to download the best driver from Github:git clone https://github.com/goodtft/LCD-show.gitchmod -R 755 LCD-showcd LCD-show/chmod +x LCD35­-show./LCD35­-show

If, after installing, the screen is a mess together with the TV missing icons or words, please connect via SSH to your Raspberry Pi and run this command:cd RetroPie­-Setup/sudo ./retropie­-setup.sh

The previous command will open the Retropie configuration file where in the end you have to look for something like SPEED and FPS and change the values to something like:dtparam=audio=ondtoverlay=tft35a,speed=62000000,fps=40,rotate=90#dtoverlay=ads7846,cs=1,penirq=17,penirq_pull=2,speed=25000000,fps=20,keep_vref$gpu_mem_256=128gpu_mem_512=256gpu_mem_1024=256overscan_scale=1

I have a perfectly running Raspberry Pi 3 Model B, with a Raspbian Distribution on a 16 GB SD-Card. I connected a Screen with a HDMI-to-DVI Connector to it, a Mouse and Keyboard and I also have SSH access. Further I got a Kuman 3.5 Inch Touch-Display, which I want to use on it. I read myself through the Internet enough that I know I can"t use the Screen and the HDMI-Screen simultaneously. So I connected the Screen to the right Pins, the Backlight already works. So I take the Drivers that are sent with it. Searched the one for my Distribution, extracted the Script onto my Raspberry Pi and launched it through./LCD-35 in the terminal. After a few seconds it Reboots and the Color-Test appears. The Screen for the NOOBS-Recovery-Mode appears, which I can still use, then a few seconds later:

UPDATE: I installed a IMG of Raspbian sent with the Display, which worked, let"s say 50 %. It worked as a mini-screen, but not more. The touch wouldn"t work. I tried to calibrate it, read and did the instructions for my screen, but nothing helped. It"s not the original problem but I"d still rather install it on a working system without the special Raspbian.

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)

1. Executing apt-get upgrade will cause the LCD to fail to work properly. In this case, you need to edit the config.txt file in the SD card and delete this sentence: dtoverlay=ads7846.

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.

I’ve gotten to the same point as OldManNiko, I installed and updated the latest Sticky Fingers pre-made image. I ran kalipi-config and set it to autologin in console with the user “pi” and configured the screen as Wave35h in kalipi-tft-config. On reboot I can see systemd load but as soon as it runs the menu the screen goes blank and there is nothing that can be done.

– kalipi-tft-config also offers Kuman 3.5″ screen as a configuration option but when I select it I get the error “Program error: Unrecognised option”. Is this a bug?

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

I put my sd card into the raspberry and the OS works but I don"t know how to install the screen, I search on forum but nothing works I have a white screen.

Also when tutorial said to download an image to install the screen: should I install win32disk on the raspberry to be able to write the screen image? Please help.

In this article, we are looking at the benefits of looking for Chinese TFT LCD manufacturers. Instead of resorting to other manufacturing means, opting for the Chinese is a much wiser and lucrative choice. If you are looking for Chinese LCD manufacturers, you should start with STONE Tech.

Handbags, wallets, phone cases, and other similar items have become the favorites of wholesalers and bulk buyers. These products are directly sold to end consumers. However, the fascinating thing about the Chinese production and manufacturing business is that it does not only cover the end-consumer products. Rather, you can also acquire raw and basic materials needed for the further manufacturing of goods and products. One such product is LCD displays.

LCD displays have become something of a necessity in today’s world of tech advancement. Many things in our daily life have been automated, and are operated using an interactive user interface. For these kinds of machines and gadgets, LCD displays are typically necessary.

In this article, we are looking at the benefits of looking for Chinese LCD manufacturers. Instead of resorting to other manufacturing means, opting for the Chinese is a much wiser and lucrative choice. If you are looking for Chinese LCD manufacturers, you should start with Stoneitech.com.

STONE Tech is an LCD manufacturer located in Beijing, China. It was founded back in 2010, and it has been developing TFT LCD display modules ever since. These modules can be used for a variety of different machines including electric equipment, precision instruments, and civil electronics etcetera.

One of the main benefits that you get with Stoneitech.com is that there is a wide range of diverse products that you can purchase. For example, there are three different application types that you can choose from which include the Industrial Type, Advanced Type, and Civil Type. Similarly, there is a range of different sizes that you can choose from. There are 11 different sizes that you can buy, ranging from the smallest 3.5-inch display to the large 15.1-inch one. The same goes for the Android series which where you can choose between 4.5-inch and 31.5-inch displays.

The same applies to LCD displays. When you save up on costs when buying LCD displays, you can set a lower price for the whole machine or gadget that you are producing.

When it comes to LCD modules, the orders are not received by the hundreds or thousands as is the case with other smaller products such as handbags and wallets etcetera. One module can cost around $250, and it is for this reason that the dynamics are a little different with this business. That is why STONE offers single pieces for sale as well as multiple pieces. This encourages smaller businesses to make their purchases since they can easily purchase as many modules as they like. As long as you meet the limit stated by the supplier, you are good to go.

In the case of LCD modules, this benefit relates to a reselling business. For example, if you are planning on buying some modules to use in your machines etcetera, then there is not a very suitable opportunity for you to expand. If you want to start a business in another country, you will have to open a manufacturing unit there so that your products can be produced and then get sold. Or, you will have to transport your final products to the other country in order to run your business.

However, if you are buying the LCD modules to resale at a profit, you can use the Chinese markets to grow your business. You can buy the modules at a reduced price and then sell them at a profit in a different area or city where the people will be willing to pay more.

Now that we have seen the benefits of choosing Chinese manufacturers for LCD modules, let us narrow it down a bit and look at why you should choose STONE specifically.

With STONE, you get the option of buying a range of different-sized modules. If your business deals in making different electronics and machines that require panels of different sizes, you don’t have to look at multiple suppliers to fulfill your need. You could be making some products that require 3.5-inch panels, while some of your machines could be needing 15.1-inch modules. Instead of taking the trouble to go to different suppliers, you can enjoy an all-in-one experience from STONE.

One of the main things that you have to look at in any supplier is the level of reliability and trust. This is usually determined by the level of experience and the time that the supplier has spent in the market. STONE was founded in 2010 and has been producing LCD modules for the past 10 years.

If you are looking to buy LCD modules in bulk, look no further than the Middle Kingdom. China has become the hub of mass manufacturing and is the favorite spot for wholesalers and business owners.

In case you need some convincing about buying from the Chinese, we have compiled a list of benefits that you can enjoy when looking for TFT LCD manufacturers in China.
