Hardware Connection

Materials needed
  • Pico-RGB-Matrix-P3-64 x 32 (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
  1. Align the pin header which is marked in red and then connect the RGB LED Matrix panel to the driver board.
  2. Cut the adapter cable (about 10cm) by plier
  3. Connect the cable which is cut in the last step to the RGB LED Matrix and the driver board
  4. Assemble the Acrylic backplane and fix it with magnetic screws
  5. Optional: If you feel that the RGB LED Matrix is too bright, you can stick the black Acrylic font panel on the Matrix.

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 effect of the instance running is shown in the following figure:

C++ SDK Development Tutorial

Development environment setup

For a complete tutorial on how to get started with the C/C++ SDK, You can directly refer to the Offical manual of Raspberry Pi.

Raspberry Pi development environment setup

If you plan to develop for Pico on the Raspberry Pi, you can quickly set up the C/C++ toolchain by running our "setup script" from the command line.
Instructions: Before running the installation script, you should make sure that the operating system on your Raspberry Pi is up to date.

Windows development environment setup

For Windows development environment construction, please refer to:

Download and burn programs

C++ SDK program programming

The following is an example of programming a simple "blinking LED" program:

  1. Download blink.uf2 ("Blink LED" flash file)
  2. Press and hold the BOOTSEL button, then plug the Pico into the USB port of your Raspberry Pi or other computer.
  3. It will be mounted as a mass storage device named "RPI-RP2". Drag and drop the blink.uf2 binary onto the "RPI-RP2" drive letter. The Pico will restart and the onboard LEDs should start blinking.

CircuitPython Development Tutorial

If you are not familiar with CircuitPython, you can first study the official recommended guide "Introduction to CircuitPython for Raspberry Pi Pico".
This guide covers the basics of getting started with CircuitPython and using the editor.

Development environment setup

In order to facilitate the programming, development and debugging of CircuitPython, it is recommended to use the "Mu Editor" development software. You can use Mu Editor for Pico's CircuitPython development on Windows.
The following describes the development and use of Mu Editor under Windows.

Windows development environment (Mu Editor) build and use

  • Download Mu Editor and follow the steps to install
  • After the installation is complete, it is the first time to configure the language and select the mode. Since we are using CircuitPython, pay attention to the mode selection CircuitPython option.
  • After the configuration is complete, it will show that the device cannot be found, that is because Pico has not downloaded the CircuitPython firmware library.
  • Download the CircuitPython firmware library and burn it into Pico
  1. Download the CircuitPython UF2 file.
  2. Press and hold the BOOTSEL button, then plug the Pico into the USB port of your Raspberry Pi or other computer. Release the BOOTSEL button after connecting the Pico.
  3. It will be mounted as a mass storage device named "RPI-RP2".
  4. Drag and drop the CircuitPython UF2 file onto the "RPI-RP2" volume. Your Pico will reboot, a new disk drive named CIRCUITPY will appear, and you're done.
  5. The new disk drive will have a default code.py file, you open it with Mu Editor, the content is: "print("Hello World!")", the specific opening steps are shown in the last figure.
  • Open the serial port, click the blank area and press Ctrl+C, then press Ctrl+D or click the blank area of ​​the code interface and press Ctrl+S to run the program. You can observe the running effect in the CircuitPython REPL window.
