=== For revisions under Rev2.1 ===
+
== Working with PC ==
* For the Raspberry Pi, comes with Raspbian driver (works with your Raspbian directly), and Ubuntu image
+
This product supports Windows 10/8.1/8/7 OS. For the Windows 10/8.1/8 OS, the touch screen supports multi-touch up to 10 points. For some Window 7 OS, the touch screen supports single touch only.
* When work as a computer monitor, touch function is unavailable
+
=== Rev2.1 New Features ===
+
* Standard HID protocol, easy to be integrated into your system.
+
* For the Raspberry Pi, supports Raspbian, Ubuntu, Windows 10 IoT, single touch, and driver free.
+
* When work as a computer monitor, supports Windows 10/8.1/8/7, five-points touch, and driver free.
+
=== How to Distinguish ===
+
* See the backside of your LCD. The Revision number "Rev2.1" printed means that the LCD firmware is Rev 2.1.
+
* However, "Rev1.1" printed on the backside doesn't mean that the LCD firmware must be Rev 1.1. Generally speaking, a LCD shipped after January 1, 2016 may be a Rev 2.1 one, although it was printed "Rev1.1".
+
  
'''Note:'''
+
Turn on the "backlight" switch then connect the LCD to your PC (USB Port of LCD -> USB Port of PC; HDMI Port of LCD -> HDMI Port of PC. Please first connect the USB Ports then connect the HDMI Port). A new touch drive will be recognized by Windows and you can use the LCD as a human interface device. When multiple displays are detected by your PC, the LCD can only be used to control the cursor on main display. So it is proposed to set the LCD as the main display.
The only difference between Rev 1.1 and Rev 2.1 is the firmware, but hardware solutions, placement and routing are all the same. (PCB printings might be different due to different production batches.)

For the Windows OS on PC, the resolution of the LCD is automatically identified. Hence, you do not need to make the relative settings. When working with Raspberry Pi, you should set the resolution of the LCD by yourself, or else the LCD screen will not work. For more detail information, please read the following section.
  
1. Using Raspberry Pi: Connect the LCD to your Pi (HDMI Port of LCD -> HDMI Port of Pi; USB Port of LCD -> USB Port of Pi; 5V~2A power supply). Download the image, e.g. Raspbian 2015-11-21 jessie or Raspbian 2015-05-05 wheezy, from [https://www.raspberrypi.org/downloads/ Raspberry Pi web site]. Write the image to a TF card and add the following code to the end of /boot/config.txt:

<font color=red>If you use the LCD with Raspberry Pi 4B, you need to remove line dtoverlay=vc4-fkms-V3D from config.txt file</font>
  
2. Without Raspberry Pi: A PC (Windows 10 / 8.1 / 8 / 7) is required which cannot connect with other display device. Connect the LCD to your PC (USB Port of LCD -> USB Port of PC; HDMI Port of LCD -> HDMI Port of PC. Please first connect the USB Ports then connect the HDMI Port). If a new touch drive is recognized by Windows, that means the firmware revision is Rev 2.1. In this case, after the driver successfully installed, you can use the LCD as a human interface device.
+
You must make sure that there are no spaces on either side of the equal sign.
  
* If the touch function doesn't work properly after these steps, the firmware revision is often Rev 1.1, which can also work by other methods, see [[7inch HDMI LCD (B) (Firmware Rev 1.1) User Manual|Rev 1.1 Manual]].

Introduction

7 inch Capacitive Touch Screen LCD, HDMI interface, supports various systems

More

Working with PC

This product supports Windows 10/8.1/8/7 OS. For the Windows 10/8.1/8 OS, the touch screen supports multi-touch up to 10 points. For some Window 7 OS, the touch screen supports single touch only.

Turn on the "backlight" switch then connect the LCD to your PC (USB Port of LCD -> USB Port of PC; HDMI Port of LCD -> HDMI Port of PC. Please first connect the USB Ports then connect the HDMI Port). A new touch drive will be recognized by Windows and you can use the LCD as a human interface device. When multiple displays are detected by your PC, the LCD can only be used to control the cursor on main display. So it is proposed to set the LCD as the main display.

Touch Settings on Win 10 PC

Some users want to connect more than one display to their PC. Here we talk about how to setting the touch to make the touchscreen to control its screen separately.

  • Connect touchscreen to PC. Here we use an standard PC monitor and connect an 7inch HDMI LCD (C) for example. We make the monitor as main screen and the touchscreen as secondary screen.
  • By default,The touchscreen can only control cursor on the main screen. Here we set it to control the secondary screen
  • Open Control Panel and search Tablet PC setting on the control panel and open the tool

  • Click button "Setup..." to setting the touchscreen

  • After click the setup you can find that there is prompt on your first screen with white color background and other screens are white.

  • If we want the touch of the touchscreen to control the desktop of the touchscreen itself. Just press Enter key to pass the first screen. And the second screen, when you find that the black text is displayed on the touchscreen, just touch the center of the touchscreen to finish this setting.
  • After this setting, the touch on the screen will just control this touchscreen even thought it is not the main screen.

Note:

1 If the first screen and the second screen are touchscreen as well, you can touch them when the text is displayed on the screens. Then you can find that all the touchscreen can work.

2 This method is just tested on win 10 PC.

Working with Raspberry Pi

For the Windows OS on PC, the resolution of the LCD is automatically identified. Hence, you do not need to make the relative settings. When working with Raspberry Pi, you should set the resolution of the LCD by yourself, or else the LCD screen will not work. For more detail information, please read the following section.

Turn on the "backlight" switch then connect the LCD to your Pi (HDMI Port of LCD -> HDMI Port of Pi; USB Port of LCD -> USB Port of Pi; 5V~2A power supply). Download the Raspbian image from Raspberry Pi web site. Write the image to a TF card and append the following lines to the config.txt file which is located in the root of your TF card:

max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=1

If you use the LCD with Raspberry Pi 4B, you need to remove line dtoverlay=vc4-fkms-V3D from config.txt file

You must make sure that there are no spaces on either side of the equal sign.

Save and connect the TF card to your Pi then power up.

(Touch input working well means that the LED firmware is Rev2.1. If the LCD firmware is 1.1, see #About LCD revision)

Note: Resolution of Ubuntu Mate OS or Windows 10 IoT Core OS can also be set properly by editing config.txt.

Rotation

Note: To rotate the touch, you can re-compile the kernel as well. There is an example for reference (use 7inch HDMI LCD (C).)

Display Rotating

To rotating the display, you can append this statement to the config file

display_rotate=1 #1: 90; 2: 180; 3: 270

Reboot the Raspberry Pi

sudo reboot

Touch rotating

With the operation above. The screen could rotate in display. However, the touch works improperly. To rotate the touch as display, you could do as below:

1. install libinput

sudo apt-get install xserver-xorg-input-libinput

2. create an xorg.conf.d folder

sudo mkdir /etc/X11/xorg.conf.d

3. copy file 40-libinput-conf to the folder which we created

sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/

4. Append a statement to touchscreen part of the file as below:

sudo nano /etc/X11/xorg.conf.d/40-libinput.conf

Touch roate.jpg
5. save and reboot your Pi

sudo reboot

After completing these steps. The LCD could rotate 90 degree both display and touch.

Note:

90 degree: Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

180 degree: Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"

270 degree: Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"

Anti-Piracy

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.

To avoid becoming a victim of pirated products, please pay attention to the following features when purchasing:
