Usage of demo
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=32 --led-cols=64For more details about the demo, please read the contents of the README.md file carefully.
Cautions of demo
- 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.
- Please do not run any programs that run in parallel with the GPIO pins.
- Disable the 1-wire interface:raspi-config -> Interface Options -> 1-Wire
- Add the isolcpus=3 statement at the end of the /boot/cmdline.txt file, separated by spaces
