How to use in the Raspberry/Ubuntu Mate/Kali/Retropie system
There are two ways to use it
The First Method
- Directly download the image we created and burn it into the micro SD card and insert it into the RaspberryPi. (Q:How to burn?)
- Image download see the image download section of the Download Resources
The second method
- Step 1, install the latest official image of various systems (Q:How to install？)
- (1)Download the latestRaspbian/Ubuntu Mate/Kali-linux/Retropieimage from the official
- (2) Format the Micro SD card using SDFormatter
- (3) Use Win32DiskImager to burn the official image to the Micro SD card
- Step 2, connect with the Raspberry Pi
- Align right-side to insert the LCD screen
- Plug-in MicroSD card, connect network and power
- Step 3, install the LCD driver
- A. Install on the Raspbian system (the Raspberry Pi needs to connect to the Internet)
- (1) Log in to the Raspberry Pi terminal(SSH remote login user name and password, see the image download of the Download Resources) (Q:The ssh can't connect?)
- (2) Execute the following command to get the LCD driver and install it (after copying, click the right mouse button in the Putty window to paste):
- A. Install on the Raspbian system (the Raspberry Pi needs to connect to the Internet)
sudo rm -rf LCD-show git clone https://github.com/goodtft/LCD-show.git chmod -R 755 LCD-show cd LCD-show/ sudo ./MHS32-show |
- B. Install on the Ubuntu Mate, Kali, Retropie system
- (1) Download the local driver, the download link is as follows: (Because of system differences, the driver downloaded from github cannot run normally
- in the three systems Ubuntu Mate, Kali, Retropie, so only local drivers can be used)
- Driver download for Ubuntu-mate-18.04 system:LCD-show.tar.gz
- Driver download for Kali-linux system:LCD-show.tar.gz
- Driver download for the retropie-rpi2_rpi3 system:LCD-show.tar.gz
- Driver download for retropie-rpi1_zero system:LCD-show.tar.gz
- (2) Log in to the Raspberry Pi terminal(SSH remote login user name and password, see the image download of the Download Resources) (Q:The ssh can't connect?)
- (3) Copy the local driver to the running Raspberry Pi system and execute the following command to extract it (can be copied by SD card or FileZilla software)
- (1) Download the local driver, the download link is as follows: (Because of system differences, the driver downloaded from github cannot run normally
- B. Install on the Ubuntu Mate, Kali, Retropie system
tar -xvzf LCD-show.tar.gz |
- (4) Execute the following command to install the LCD driver
chmod -R 755 LCD-show cd LCD-show/ sudo ./MHS32-show |
- Step 4, Check if the driver is successfully installed
- (1) 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.
- (1) After the LCD driver is installed, the system will automatically restart. After the startup is successful, the LCD can display and touch normally,
Note:
- A. Ubuntu system default SSH is not enabled, the specific method of opening seeRaspberryPi Ubuntu-mate open ssh instructions
- B. Ubuntu-18.04 system ssh connection may fail, the specific solution is shown in RaspberryPi Ubuntu-mate-18.04 ssh connection failure solution description
- C. The retropie-rpi1_zero system cannot log in via SSH (no network port and wifi module). You need to copy the driver through the serial port. For details, see RaspberryPi Zero open serial instructions
- D. Retropie system game installation and setup instructions see RaspberryPi Retropie using instructions
How to rotate the display direction
This method only applies to the Raspberry Pi series of display screens, other display screens do not apply.
- Method 1，If the driver is not installed, execute the following command (Raspberry Pi needs to connected to the Internet):
sudo rm -rf LCD-show git clone https://github.com/goodtft/LCD-show.git chmod -R 755 LCD-show cd LCD-show/ sudo ./XXX-show 90
After execution, the driver will be installed. The system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.
（ ' XXX-show ' can be changed to the corresponding driver, and ' 90 ' can be changed to 0, 90, 180 and 270, respectively representing rotation angles of 0 degrees, 90 degrees, 180 degrees, 270 degrees）
- Method 2，If the driver is already installed, execute the following command:
cd LCD-show/ sudo ./rotate.sh 90
After execution, the system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.
（ ' 90 ' can be changed to 0, 90, 180 and 270, respectively representing rotation angles of 0 degrees, 90 degrees, 180 degrees, 270 degrees）
If the rotate.sh prompt cannot be found, use Method 1 to install the latest drivers
