uctronics 3.5 inch hdmi tft lcd display with touch screen factory

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 want to use the touch function, you need to download and install the driver manually refers to the instructions we provided. The driver includes the settings of the Raspbian OS resolution and touch screen support.

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.

UCTRONICS U6111 is a 3.5” TFT LCD display with SPI interface and touchscreen support. It works with all standard Raspberry Pi models and supports operating systems like Raspbian, Ubuntu, Kali and RetroPie. Windows 10 IoT is NOT supported.

Visibility is... rough. The panel used appears to have originally been designed for a vertically oriented use, but it"s a TN display. The net result is that half the screen is brighter than the other when viewed dead-on from the center. Viewing angle is extremely biased towards one side of the screen.

There"s a tad bit of overscan on the side with the fatter border (I"m driving the screen at 800x600 at the moment), so adjust your Pi"s config to suit.

Also, seriously, don"t drive this higher than 800x600 if your use case lets you control the input resolution The screen is way too small and way too low resolution (480x320!) to be useful beyond that. UI elements and text are baaaaaarely usable at 800x600.

Overall, it"s easy, reasonably well designed, and the worst issues of the lot are the rather awkward viewing angles and the screen tearing.. It"s not very expensive, takes HDMI, and fits perfectly (like, it"s actually perfect) onto a Pi 2 or 3.

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 want to use the touch function, you need to download and install the driver manually refers to the instructions we provided. The driver includes the settings of the Raspbian OS resolution and touch screen support.

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.

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.

Tutorial link: http://www.lcdwiki.com/MHS-3.5inch_RPi_DisplayProduct Advantage:1.The power interface is designed on the screen PCB board. It can be connected to the fan, which can cool the Raspberry Pi quickly with the heat sink

5.If you feel hard to install driver for screen, we offered the Pre-install Driver System in Tutorial to test screen working statues. 6.The Screen also Support Pi 3 B+, Pi 2. (The Case only suit for Pi 4).Notice:1. When the screen is connected, GPIO cannot be used. And Don"t have backlight ON/Off Key

2. Need to install the driver. Some customers often say that the system crashes or there is nothing on the screen after installation (If you are not familiar with the Raspberry Pi, We strongly recommended you that use the system with the driver installed)

In the previous article, I described the steps needed to install an LCD touchscreen on the Raspberry Pi. In this article, I will show you how to adjust the screen rotation of the LCD to landscape mode, and will show you how to calibrate the touchscreen pointer for optimal accuracy. Just follow the steps below to compete the process of setting up your Raspberry Pi LCD touchscreen:

1. First we need to change the setting for screen rotation in the /boot/cmdline.txt file. This setting is called fbtft_device.rotate=X. By default, this is set to X=0, which results in a portrait mode screen orientation. In order to switch the orientation to landscape mode, change fbtft_device.rotate=0 to fbtft_device.rotate=90. Enter sudo nano /boot/cmdline.txt at the command prompt. There should only be one line in this file. Go to the end of it and you will find the fbtft_device.rotate=X setting. Change the value from 0 to 90:

However, if you try to touch the screen now, you will find that the pointer movement does not correspond to your finger movement. This is because the LCD screen driver and the touchscreen controller driver have separate settings for screen rotation. We need to change the rotation of the touchscreen controller driver to match the rotation of the LCD screen driver.

2. You probably noticed that dragging your finger to the right moves the pointer up, not to the right. This indicates that the x and y axes of the touchscreen are swapped. To correct this, we need to swap the x axis for the y axis. This can be done by changing the swap_xy=X parameter in /etc/modules.

Now if you drag your finger around the screen, you will notice that the y axis (up and down) is correctly aligned with the motion of your finger. However, the x axis (left and right) is still inverted. To fix this, we need to install two more kernel modules, xinput and evtest. xinput is a Linux utility that will allow us to configure input device settings for the touchscreen controller, and evtest is an input device event monitor and query tool.

After the Pi finishes rebooting, you should notice that when you move your finger across the touch screen, the pointer should follow correctly in both axes. If you are using the Raspberry Pi 2 Model B, you will need to complete the calibration steps below before the pointer follows your finger correctly (and make sure that you have enabled startx to load automatically – see step 6 in this article).

You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.

Now that we have our LCD touchscreen up and running, the final step in the installation is the calibration of touch control. This will make the pointer much more accurate and easier to use.

2. Now we need to install the calibration tool we will be using, xinput_calibrator; and other filters for controlling the touchscreen response. Install the tslib library by entering aptitude install libts-bin:

4. Now we can use ts_calibrate. Enter ts_calibrate at the command prompt (make sure you are still in root mode) to run the ts_calibrate program. The program will consecutively display five crosses on different parts of the screen, which you need to touch with as much precision as possible:

Drag the cross around the screen and observe how closely it follows your finger or stylus to test the accuracy of the calibration. Now press the “Draw” button to enter the drawing mode:

This is kind of a long process, but it is well worth it if you want to get the LCD touchscreen set up properly. So if you have any trouble setting this up or have anything to say, please leave a comment below. Also, if you found this article useful, please share it with your friends!
