Working With Raspberry Pi

Hardware Connection

Method 1: Back Lock Installation

1. Connect the DSI interface of the LCD to the DSI interface of the Raspberry Pi board.
2. The Raspberry Pi is installed on the display board with the back facing down, and the 5V power supply and I2C communication are connected through the 4PIN.
The Raspberry Pi 4B back lock installation effect is as follows:

Method 2: Flat Connection

1. Use a 15PIN FPC cable to connect the DSI interface of the display to the DSI interface of the Raspberry Pi board.
2. Using a USB cable, connect the USB port of the Raspberry Pi to the Type-C port on the display baseboard.
The Raspberry Pi 4B flat installation effect is as follows:

The CM4 IO Board flat installation effect is as follows:（Use DSI1 interface）

Software Setting

Method 1: Install Manually

1. Download the image of the newest version Raspberry Pi, download the compressed file to the PC and extract the .img file.
   
2. Connect TF card to PC, use SDFormatter to format TF card.
   
3. Open Win32DiskImager software, select the system image prepared in step 1 and click write to burn the system image.
   
4. After the programming is completed, connect the TF card to the Raspberry Pi, start the Raspberry Pi, and log in to the terminal of the Raspberry Pi (you can connect the Raspberry Pi to an HDMI display or log in remotely with ssh).
   

#Step 1: Download and enter the Waveshare-DSI-LCD driver folder
git clone https://github.com/waveshare/Waveshare-DSI-LCD
cd Waveshare-DSI-LCD
 
#Step 2: Enter uname -a in the terminal to view the kernel version and cd to the corresponding file directory
#5.15.61 then run the following command
cd 5.15.61
 
#Step 3: Please check the bits of your system, enter the 32 directory for 32-bit systems, and enter the 64 directory for 64-bit systems
cd 32
#cd 64
 
#Step 4: Enter your corresponding model command to install the driver, pay attention to the selection of the I2C DIP switch
#8inch DSI LCD (C) 1280×800 driver:
sudo bash ./WS_xinchDSI_MAIN.sh 80C I2C0
 
#Step 5: Wait for a few seconds, when the driver installation is complete and no error is prompted, restart and load the DSI driver and it can be used normally
sudo reboot

Note: The above steps need to ensure that the Raspberry Pi can be connected to the Internet normally.
5. Wait for the system to restart, it will be able to display and touch normally.

Method 2: Program Pre-installed Image

• Download the 8inch DSI LCD - Pi4 pre-installed image and unzip to get ".img" file.
• Connect the TF card to the PC and use SDFormatter to format the TF card.
• Open Win32DiskImager software, choose the image and click "write" to program the system image.
• After programming, you can connect the TF card to the Raspberry Pi and then boot it. Just wait for about 30 seconds to display and touch.

Rotation

Method 1: Graphical Interface Rotation

In the start menu, select: Preferences->Screen Configuration->Configure->Screens->DSI-1->Orientation, select the corresponding angle in it, click "√", select Yes, and restart.

Method 2: Rotation Display In Lite Version

sudo nano /boot/cmdline.txt
#Add a command corresponding to the display rotation angle at the beginning of the cmdline.txt file, save it and restart it to take effect
#display rotated 90 degrees
video=DSI-1:1280x800M@60,rotate=90
#display rotated 180 degrees
video=DSI-1:1280x800M@60,rotate=180
#display rotated 270 degrees
video=DSI-1:1280x800M@60,rotate=270

Touch To Rotate

sudo nano /boot/config.txt
#Modify the instruction of the touch rotation angle at the end of the config.txt file, and it will take effect after restarting (there is a 0° touch direction instruction by default)
#0°:
dtoverlay=WS_xinchDSI_Touch,invertedx,swappedxy
#90°:
dtoverlay=WS_xinchDSI_Touch,invertedx,invertedy
#180°:
dtoverlay=WS_xinchDSI_Touch,invertedy,swappedxy
#270°:
dtoverlay=WS_xinchDSI_Touch

Backlight Control

Method 1: Graphical Interface Dimming

Using the application provided by Waveshare:

cd Waveshare-DSI-LCD
# Determine the currently used kernel version, such as the 5.15.61 kernel, and run the following command
cd 5.15.61
#Check the bits of the system, 32-bit system enters 32 directory, 64-bit system enters 64 directory
cd 32
#cd 64
cd Backlight
sudo ./install.sh

After the installation is complete, you can open the program in the Start menu - > Accessories - > Brightness, as shown below:

Method 2: Lite Version Dimming Command

To adjust the system command of the lite version, after entering the root privilege, execute the following command on the Raspberry Pi terminal:

echo X > /sys/waveshare/rpi_backlight/brightness

(X value in the range of 0~255)
For example:

sudo su root
echo 100 > /sys/waveshare/rpi_backlight/brightness

Disable Touching

At the end of the config.txt file, add the following commands corresponding to disabling touch (the config file is located in the root directory of the TF card, and can also be accessed through the command: sudo nano /boot/config.txt):

disable_touchscreen=1

Note: After adding the command, it needs to be restarted to take effect.

Notes

1. Update the system

sudo apt-get update
sudo apt-get full-upgrade

After updating the system, some files of the originally installed driver will be overwritten, in this case the driver needs to be reinstalled to display normally.

2. Replace the motherboard

If the driver was originally installed on Raspberry Pi 4 Model B, the user replaces the motherboard, such as modifying it to Raspberry Pi 3 Model B+, which will cause the display to fail to display normally. Because Pi4 and Pi3 need to load different driver files.

In this case, the driver needs to be reinstalled on the new motherboard to display normally.
