【Download】

[] Image: 2inch-240x320-230822.img

[] schematic diagram: 2inch LCD 240x320 with buzzer-230426.pdf

[] Key program: key_test.py

[] Display drive: lcd2.dtbo


【Configuration display】

[] Download lcd2.dtbo copy to /boot/overlays/

Increase display configuration

sudo nano /boot/config.txt

And add that follow code in the configuration file:

dtparam=spi=on

dtoverlay=lcd2:rotate=270

hdmi_force_hotplug=1

max_usb_current=1

hdmi_group=2

hdmi_mode=1

hdmi_mode=87

hdmi_cvt 480 320 60 6 0 0 0

hdmi_drive=2

display_rotate=0

Attention! In the configuration file of Raspberry Pi, please comment out two lines of code dtoverlay=vc4-kms-v3d and max_framebuffers=2:

#dtoverlay=vc4-kms-v3d

#max_framebuffers=2


【Download, compile and install fbcp】

sudo apt update

sudo apt-get install git -y

sudo git clone https://github.com/tasanakorn/rpi-fbcp.git

cd ./rpi-fbcp/

sudo mkdir -m 777 ./build

cd ./build/

sudo apt install libraspberrypi-dev -y

sudo apt-get install cmake -y

sudo cmake ..

sudo make

sudo install fbcp /usr/local/bin/fbcp


【Set auto-start startx and fbcp】

sudo nano ~/.bash_profile


Note: If there is no .bash_profile file, create one yourself


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

if [ "$(cat /proc/device-tree/model | cut -d ' ' -f 3)" = "5" ]; then

# Raspberry Pi 5B configuration

export FRAMEBUFFER=/dev/fb1

startx 2> /tmp/xorg_errors

else

# Non-Raspberry Pi 5B configuration

export FRAMEBUFFER=/dev/fb0

sleep 20

fbcp &

startx 2> /tmp/xorg_errors

fi


【Set CLI automatic login】

sudo raspi-config nonint do_boot_behaviour B2

Noto: This command has optional parameters

B1 - Boot to console, requiring login

B2 - Boot to console, logging in automatically

B3 - Boot to desktop, requiring login

B4 - Boot to desktop, logging in automatically

Note: Make sure the username of the Raspberry Pi is pi, otherwise it will not log in automatically


【Switch to X11】

sudo raspi-config nonint do_wayland W1

Note: This command has optional parameters

W1 - Use the X11 backend

W2 - Use the Wayland backend


【The above configuration will take effect after restart】

sudo reboot

Note: After setting all the above configurations, the system will become longer during each restart, and SSH also needs to wait for a while to enter;


【Configure speakers】

Edit configuration file:

sudo nano /boot/config.txt

Add to the configuration file

dtoverlay=audremap,pins_18_19

Save to exit, and then restart:

sudo reboot


Enter the command at the terminal after restarting.

sudo raspi-config

Select system options-> audio->' headset' and restart again.


Enter the system interface, just find an mp3 file and double-click it to play it. If it can play normally, it will be fine.


【Key code test】

Download key_test.py Running code:

sudo python3 ./key_test.py

Press the module button at this time, and the terminal will output a prompt message.
