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):

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)

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.

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. After installing this driver, the HDMI output will be disabled. To switch back to the HDMI display, execute:

sudo ./LCD-hdmi

E. Retropie system game installation and setup instructions see RaspberryPi Retropie using instructions
