Raspberry Pi 7inch HDMI LCD User Guide

Introduction

7inch Resistive Touch Screen LCD, HDMI interface, Designed for Raspberry Pi

Button description

Power: Turn on or turn off the LCD screen.

Menu: Open the OSD menu (when using the menu, this button can be served as Confirm)

Up/Left: Direction button.

Down/Right: Direction button.

Return: Close the OSD menu.

• If the LCD is not in use for a long time, you can press the Power button to turn off the LCD and lower the power consumption.
• You can press the Menu button to open the OSD menu as the figure shown, then press the direction button to select. Some of the options are reserved and without any effect, e.g. in fact the Volume option won't affect the volume.

Getting Started

Hardware Connection

1. Plug the LCD to your Raspberry Pi:
   • There are 40 pins on Raspberry Pi Model A+/B+/2 B/3 B but only 26 pins on the LCD, so you should pay attention to connecting the pins to your Pi accordingly.
2. Connect the HDMI Connector to both the HDMI interfaces on the LCD and the Pi.
   • You should connect the LCD to Raspberry Pi Model B or Raspberry Pi Zero with an HDMI cable rather than an HDMI Connector.
3. Turn on the "backlight" switch on the back of the LCD.

You can enable the touch in two ways: Method 1. install driver to your Raspbian/Ubuntu Mate OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.

Method 1. Driver installation

Description: The driver can be downloaded from github

git clone https://github.com/waveshare/LCD-show.git

1) Download the Raspbian / Ubuntu Mate image from Raspberry Pi website and extract it on a PC.

2) Connect your micro SD card to the PC and write the image to the card using Win32DiskImager. How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details)

3) Copy the LCD driver to the micro SD card (or copy the driver to the system of Pi using a USB drive).

4) Append the following lines to the config.txt file which is located in the root of the card:

max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0

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

5) The LCD will display after booting up. Then open a terminal to install the touch driver which can be found in the /boot/ directory.

git clone https://github.com/waveshare/LCD-show.git
cd LCD-show/
chmod +x LCD7-1024x600-show
./LCD7-1024x600-show

Touch function will work after restart. For ease of use, you can set the screen orientation, see: #Screen orientation settings.

Method 2. Using Ready-to-use image

The image file with pre-installed driver is located in the IMAGE directory of the CD, or you can download it from #Image. Extract the .7z file and you will get an .img file. Write the image to your micro SD card (How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details). Then insert the card to your Pi, power up and enjoy it.

Screen orientation settings

After touch driver installed, the screen orientation can be set by these commands:

• 0 degree rotation

cd LCD-show/
./LCD7-1024x600-show 0

• 90 degree rotation

cd LCD-show/
./LCD7-1024x600-show 90

• 180 degree rotation

cd LCD-show/
./LCD7-1024x600-show 180

• 270 degree rotation

cd LCD-show/
./LCD7-1024x600-show 270

Touch screen calibration

• Install the X server first

sudo apt-get install xserver-xorg-input-evdev
sudo cp -rf /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
sudo reboot

• This LCD can be calibrated using a program called xinput_calibrator which can be downloaded from Xinput-calibrator_0.7.5-1_armhf
• Extract and copy the software Xinput-calibrator_0.7.5-1_armhf.deb to the Raspbian of your Pi.
• Install it with the commands:

sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb 

• Click the "Menu" button on the task bar, choose "Preference" -> "Calibrate Touchscreen".
• Finish the touch calibration following the prompts. Maybe rebooting is required to make calibration active.
• You can create a 99-calibration.conf file to save the touch parameters (not necessary if file exists).

/ect/X11/xorg.conf.d/99-calibration.conf

• Save the touch parameters (may differ depending on LCD) to 99-calibration.conf, as shown in the picture:

Right click emulation

• Edit the 99-calibration.conf file.

sudo nano /etc/X11/xorg.conf.d/99-calibration.conf

• Append the following lines between "Section" and "EndSection":

Option "EmulateThirdButton" "1"
Option "EmulateThirdButtonTimeout" "750"
Option "EmulateThirdButtonMoveThreshold" "100"

• Exit with save and reboot the system.

reboot

Tips

Display images on Linux console

• Install the fbi software.

sudo apt-get install fbi

• Save image files to a specified direction (/dev/fb0 for example) and display them with:

fbi -T 2 -d /dev/fb0 -noverbose -a XXX.jpg

Play videos

• Install the mplayer software.

sudo apt-get install mplayer

• Save video files to the current directory and you can play them with:

mplayer XXX.mp4
