This display uses the open source code on github to demonstrate. Please access the Raspberry Pi terminal, and then enter the following commands in turn:
sudo git clone https://github.com/hzeller/rpi-rgb-led-matrix
cd rpi-rgb-led-matrix
sudo make
cd examples-api-use
sudo ./demo -D 9 --led-rows=64 --led-cols=64
For more details about the demo, please read the contents of the README.md file carefully.
Cautions of demo:
1. Turn off onboard audio.
Please modify the content of /boot/config.txt into dtparam=audio=off, because the on-board audio and the timing circuitry required by RGB-Matrix cannot be run simultaneously.
2. Please do not run any programs that run in parallel with the GPIO pins.
3. Disable the 1-wire interface:raspi-config -> Interface Options -> 1-Wire
4. Add the isolcpus=3 statement at the end of the /boot/cmdline.txt file, separated by spaces

Usage of Demo:
The Arduino IDE version used in this demo is arduino-ide_2.3.2_Windows_64bit
1.Download and unzip the ESP32_Packages folder (the unzipped esp32 folder will have "hardware" and "tools" subfolders), copy the unzipped esp32 folder to the packages under the installation directory of Arduino IDE, such as C:\Users\Admin\AppData\Local\Arduino15\packages (Admin is the user name of my computer, which needs to be replaced according to the actual user name of your computer), as shown in the figure below:
2. Copy the files in the downloaded demo codes\ESP32\libraries folder to the libraries in the installation directory of Arduino IDE; for example, the path on my computer is C:\Users\Admin\Documents\Arduino\libraries ('Admin' is the user name of my computer, which needs to be replaced according to the actual user name of your computer);
3. After connecting the power cable to the screen and connecting the signal cable according to Table 2-4, enter the ESP32 folder and you will find 4 subfolders: SimpleTestShapes, PatternPlasma, BouncingSquares, AurroraDemo, where SimpleTestShapes is for basic shape display, PatternPlasma is for plasma pattern display, BouncingSquares is for bouncing square display, and AurroraDemo is for animation effect display;
4. Select the appropriate board and port according to the ESP32 module model you are using, as shown in Figure 2-4 below:
