የሃርድዌር ውቅር
- The LCD module adopts the in-line design, and can be directly inserted into the GPIO port of the RaspberryPi development board according to the wiring requirements, and does not need to be deliberately wired. The module also contains two modules: touch control circuit, LCD display control circuit.
- The touch control circuit is responsible for controlling touch events, including powering the touch control IC, acquiring touch breaks, acquiring ADC values of touch locations, and touch calibration.
- The LCD display circuit is responsible for LCD display control, including GPIO control of the LCD screen, display of color value reading and writing, and register configuration.

The First Method
- directly download the system image file we provided, burn it into the micro SD, and then put it on the RaspberryPi. For the specific burning method, see the following file:
http://www.lcdwiki.com/res/PublicFile/How_to_use_Raspberry_Pi(Download,Format,Burn,SSH,PuTTy)-V1.0.pdf - ምስሉ file download can be downloaded from the resource download section of the following URL. http://www.lcdwiki.com/2.4inch_RPi_Display_For_RPi_3A+
The Second Method
- download the latest official system image file
ባለሥልጣኑ website of each system is as follows:
Raspbian: https://www.raspberrypi.org/downloads/
ኡቡንቱ፡ https://ubuntu-mate.org/raspberry-pi/
Kali-linux: https://www.offensive-security.com/kali-linux-arm-images/ - make a system image file
The specific production methods are as follows: http://www.lcdwiki.com/res/PublicFile/How_to_use_Raspberry_Pi(Download,Format,Burn,SSH,PuTTy)-V1.0.pdf - connect to RaspberryPi
Insert the LCD screen holder to the right to insert the Raspberry Pi pin.
Insert the MicroSD card that burns the official system image file, connect the network cable, and connect the power supply. - install LCD driver
Install on the Raspbian system (the Raspberry Pi needs to connect to the Internet)
-
- Open the putty connection ssh, enter the username and password to log in to the Raspberry Pi terminal (the default username and password are shown in the table below).

- Open the putty connection ssh, enter the username and password to log in to the Raspberry Pi terminal (the default username and password are shown in the table below).
Install on the Ubuntu Mate, Kali system
- Download the local driver(Because of system differences, the driver downloaded from github cannot run normally in the two systems Ubuntu Mate, Kali, so only local drivers can be used)
The local driver download can be found in the LCD driver section of Method 2 used in the Raspberry/Rbbian/Ubuntu Mate/Kali system on the following page. http://www.lcdwiki.com/2.4inch_RPi_Display_For_RPi_3A+ - Open the putty connection ssh, enter the username and password to log in to the Raspberry Pi terminal (the default username and password are shown in the table below).

tar –xvzf LCD-show.tar.gz - Execute the following command to install the LCD driver
chmod -R 755 LCD-show cd LCD-show/
sudo ./LCD24-ትዕይንት - Check if the driver is successfully installed
After the LCD driver is installed, the system will automatically restart. After the startup is successful, the LCD can display and touch normally,indicating that the driver installation is successful.
