Software Settings

Method 1: Flash Latest Bookworm System

1. Connect the TF card to the PC, download and use Raspberry Pi Imager to flash the corresponding system image.

2. After the image flashing is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of the config.txt, save and safely eject the TF card.

Note: Since Pi5/CM5/CM4/CM3+/CM3 has two mipi DSI interfaces, please note that the correct DSI interfaces and commands are used, DSI1 is recommended by default.

dtoverlay=vc4-kms-v3d
#DSI1 Use
dtoverlay=vc4-kms-dsi-waveshare-panel-v2,5_0_inch_a
#DSI0 Use
# dtoverlay=vc4-kms-dsi-waveshare-panel-v2,5_0_inch_a,dsi0

3. Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and generally wait for about 30 seconds to enter the display state. The touch function can be used normally after the system boots.

Method 2: Flash Pre-installed Image

1. Select pre-installed image, download and unzip it as .img file

• 5-DSI-TOUCH-A pre-installed image
  

2. After the image flashing is completed, connect the TF card to the Raspberry Pi, start the Raspberry Pi, and wait for about 30 seconds for it to be displayed and touched normally.

Adjust Backlight Brightness

• 1. Open the "Screen Configuration" application;
  

• 2. Go to "Screen" -> "DSI-2" -> "Brightness", check the backlight brightness you need to set, and finally click "Apply" to complete the backlight setting.

Waveshare also provides a corresponding demo (the demo is only used for Bookworm and Bullseye systems), users can download, install and use in the following way:

1. Download the compressed demo package
 wget https://files.waveshare.com/wiki/common/Brightness.zip
2. Unzip the package
 unzip Brightness.zip
3. Enter the program directory
 cd Brightness
4. Grant execution permissions to the installation script
 sudo chmod +x install.sh
5. Execute the installation script
 ./install.sh

In addition, you can also control the brightness of the backlight by entering the following command on the terminal:

echo X | sudo tee /sys/class/backlight/*/brightness

Where X represents any number from 0 to 255. 0 means the darkest backlight, and 255 means the brightest backlight. For example:

echo 100 | sudo tee /sys/class/backlight/*/brightness
echo 0 | sudo tee /sys/class/backlight/*/brightness
echo 255 | sudo tee /sys/class/backlight/*/brightness

Use Touchscreen Virtual Keyboard

Raspberry Pi OS Bookworm and later versions include Squeekboard on-screen keyboard by default.
When connecting to the touch display, the on-screen keyboard will automatically appear if text input is possible, and it will automatically hide if text input is not possible.
For applications that do not support automatic text input detection, you can manually display or hide the on-screen keyboard by clicking the keyboard icon at the far right of the task bar.

You can also display or hide the screen keyboard through the "Display" option under "Raspberry Pi Configuration" or through the "Display" section in raspi-config.

• Note:

For versions of Raspberry Pi OS before Bookworm, use matchbox-keyboard. If you are using the wayfire desktop compositor, use wvkbd.

Bookworm Touch Screen Rotation

• 1. Open the "Screen Configuration" application;
  

• 2. Go to "Screen"->"DSI-2"->"Touchscreen", check "11-005d Goodix Capacitive TouchScreen", and click "Apply" to complete the selection of the specified touchscreen;
  

• 3. Go to "Screen"->"DSI-2"->"Orientation" , check the direction you need to rotate, and finally click "Apply" to complete the display and touch synchronous rotation.
  

Note: Only the Bookworm system supports the above synchronization rotation method. For Bullseye and Butser systems, after displaying rotation, touch rotation needs to be manually set separately.

Touch Mode Selection

The Bookworm system supports two touch modes, which can be switched in the Screen Configuration > Touchscreen menu:

• 1. Mouse Emulation (default)

Click = Left mouse button function
Long press = Right mouse button function
Supports double-click
Does not support page swiping and multi-touch functionality

Note: This mode is suitable for scenarios that require mouse operation, such as double clicking to open the file manager and long pressing to achieve right-click functionality.

• 2. Multitouch

Supports multi-touch functionality
Supports swiping pages
Does not support double-click and right-click long press functions

Note: This mode is suitable for touch-optimized scenarios, such as web browsing and scrolling lists.

lite Version Display Rotation

sudo nano /boot/firmware/cmdline.txt
#Add the display resolution and rotation commands at the beginning of the cmdline.txt file to take effect after a reboot
# For example, DSI-1 display with 8000x1280 resolution, showing rotated 90 degrees
video=DSI-1:800x1280M@60,rotate=90
# For example, DSI-1 display with 8000x1280 resolution, showing rotated 180 degrees
video=DSI-1:800x1280M@60,rotate=180
# For example, DSI-1 display with 8000x1280 resolution, showing rotated 270 degrees
video=DSI-1:800x1280M@60,rotate=270

Note:

• 1. Based on actual display resolution.
• 2. If using Pi5/CM5, use the actual DSI display number identified, for example, "DSI-2".
• 3. Unable to rotate DSI monitor and HDMI monitor separately using cmdline.txt. When you use both DSI and HDMI simultaneously, they share the same rotation value.

Show Rotation

• Rotation command

#Rotate 90 degrees
xrandr -o left
#Rotate 270 degrees
xrandr -o right
#Rotate 180 degrees
xrandr -o inverted
#Rotate 0 degrees
xrandr -o normal

• The effect of using xrandr rotation is a one-time and the screen orientation is restored after the system restarts. If you want the device to rotate automatically upon startup, you need to modify the configuration file:

sudo vim  /etc/X11/xorg.conf.d/10-monitor.conf

Add the following statement:

### Valid values for rotation are "normal", "left", "right"
Section "Monitor"
#    Identifier "Default Monitor"
    Identifier  "DSI-1"
    Option      "Rotate" "left"
EndSection

ESP32-P4

Screen Driver

The ESP32-P4-NANO drives the screen via MIPI 2-lane

1. The screen driver has been packaged as a component, with the component located at ESP Component Registry
   Use idf.py add-dependency "waveshare/esp_lcd_hx8394" to add components to your ESP-IDF project
2. You can also directly view the Wiki that describes how ESP32-P4-NANO drives the screen: ESP32-P4-NANO_MIPI-DSI

Backlight Control

After connecting the ESP32-P4-NANO with the matching FPC cable and power cable, the backlight can be controlled by writing 0x00~0xFF (full brightness) to the 0x45 device and 0x96 register on the screen through the ESP32-P4-NANO I2C

If you use the ESP32-P4-NANO BSP component, you can control it directly by the following functions

bsp_display_brightness_init();    // Initialize the backlight

bsp_display_backlight_on();       // Turn on the backlight, default full brightness

Bsp_display_backlight_off();      // Turn off the backlight

bsp_display_brightness_set(95);   // Set the specific backlight brightness, 0~100
