unzip ./Waveshare32b.zip
sudo cp waveshare32b.dtbo /boot/overlays/

Edit config.txt file

sudo nano /boot/firmware/config.txt

Block the statements in the figure below

Add the following code at the end of the config.txt

dtparam=spi=on
dtoverlay=waveshare32b

max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 640 480 60 6 0 0 0
hdmi_drive=2
display_rotate=0

2. Set auto-start on boot

• Open .bash_profile file and create one yourself if you don't have a .bash_profile file

sudo nano ~/.bash_profile

Add the following code to the bottom of the .bash_profile file

export FRAMEBUFFER=/dev/fb1
startx  2> /tmp/xorg_errors

• Open the 99-fbturbo.~ file, if the file already exists, you need to confirm that fb is fb0

sudo nano /usr/share/X11/xorg.conf.d/99-fbturbo.~

Add the following to the 99-fbturbo.~ configuration file

Section "Device"

After a restart, the screen will display normally

sudo reboot

Method 1: Install Driver

Please download the latest version of the image (Raspbian/Ubuntu Mate/Kali or Retropie) at Raspberry Pi official website. For convenience, Raspbian images are provided here:

• 3.2inch RPi LCD (B)_220906_32_bullseye_CM4.zip

1) Download the image file to the PC, and extract it as .img file.

2) Connect the TF card to the computer, open the Win32DiskImager.exe software, select the .img file prepared in step 1, and click Write to flash the system image. After the image flashing is complete, safely eject the TF card.

3) 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 the HDMI display or use ssh to log in remotely).

4) First download the relevant driver code through the network, then execute the corresponding installation command, ensuring you have a stable Internet connection throughout the process.

git clone https://github.com/waveshare/LCD-show.git
cd LCD-show/
sudo ./LCD32-show

It can be used after restarting (for convenience, the screen orientation can be adjusted, see #Set Screen Orientation).

Note 1: Executing apt get upgrade will cause the LCD to malfunction. At this point, you need to edit the config.txt file in the TF card and delete this line: dtoverlay=ads7846.

Note 2: Under Raspbian-lite, you need to run the sudo ./LCD32-show lite command to install the driver.

Method 2: Use Pre-installed Driver Image

Here is a pre-installed driver image, extract it and write it to the TF card (Open the Win32DiskImager.exe software, select the .img file, and click Write to flash the system image). Then insert the card into the Raspberry Pi to use it.

• 3.2inch RPi LCD (B)_220906_32_bullseye_CM4.zip
• RPi_LCD_Bookworm_64bit_6.6.31.img.zip

Set Screen Orientation

Once the touch driver is installed, you can modify the screen rotation direction by running the following commands.

cd LCD-show/
#X can be 0, 90, 180, and 270. They respectively represent LCD rotation of 0 degrees, 90 degrees, 180 degrees, and 270 degrees.
sudo ./LCD32-show X

The rotation command under Raspbian-lite is as follows:

cd LCD-show/
#X can be 0, 90, 180, and 270. They respectively represent LCD rotation of 0 degrees, 90 degrees, 180 degrees, and 270 degrees.
sudo ./LCD32-show lite X
