Demo example

Hardware connection

Materials needed

  • Pico-RGB-Matrix-P3-64x32 (this product)
  • Raspberry Pi Pico (must be purchased separately, if not, it is recommended to buy a version with soldered headers, which is convenient for direct insertion and use)
  • Micro USB cable (must be purchased separately)

Hardware connection steps

Example display

Multi-Features Digital Clock

This example is developed based on the C++ SDK. In order to quickly demonstrate the effects and functions of the example, you can skip the steps of " Building a C++ SDK Development Environment " and "Program Debugging and Development" and directly " download and burn the program ". After the burning is completed, the running effect of the example is shown in the figure below:

【Function Description】

  • Time display screen:
    • Display date, day of the week, hour, minute, lunar calendar and temperature
  • Function setting menu
    • Date setting
    • time setting
    • BEEP setting (buzzer setting)
    • Auto brightness
    • Language setting (under development)

Fruit machine

This example is developed based on CircuitPython[1] , and the program is downloaded[2] . The effects and functions of the example are as follows:

【Function Description】

  • The display can display a variety of fruits or other small BMP icons
  • Automatically scroll icons at regular intervals, and randomly display the results of the scrolling
  1. CircuitPython是MicroPython的一个分叉,具体使用请见 RGB-Matrix相关CircuitPython教程
  2. Pico须先安装CircuitPython,然后再把对应的CircuitPythond代码复制到识别到的U盘上,即可完成下载。


Infrared transceiver test

This example is developed based on MicroPython, the program is downloaded , the example effects and functions are as follows::
