Overview

The Pico-RGB-LED is an LED matrix module designed for Raspberry Pi Pico, which has 160 (16 × 10) RGB full-color external-controlled constant current integrated LEDs, with embedded quality controller IC and LED chip. It is small in size, uses very few peripheral components, and presents a clean-looking front panel. Controlled by a Raspberry Pi Pico, this LED panel is programable for a high-level, colorful matrix display.

Feature

• Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series.
• 160 RGB LEDs arranged in a 16 × 10 grid, multiple IO selection.
• Right-angled 2.54mm pitch male pin header on the bottom, for easy extension.
• 0807 colorful LEDs, integrating quality single wire cascading constant current driver IC and quality RGB LED chip, aka external-controlled constant *current integrated LEDs.
• Embedded controller IC, with features like high reliability, high anti-interference performance, high constant current accuracy, and low power consumption.
• Integrated quality LED chip, with high consistent brightness and pure white light effect, lower light degradation.

Specifications

• Operating voltage: 5V
• Communication: Single wire return to zero code
• Color depth: 24-bit (each 8-bit of RGB)
• Data rate: 800Kbps
• Brightness: adjustable 256 level
• Pixels: 16 x 10 pixels
• Dimensions: 54.00 x 26.00mm

About the RGB LED

Lamp bead used single communication way, with the method of zero code signal. After the chip is powered on and reset, it receives the data from the DIN end. After receiving enough 24 bits, the DO port begins to forward data for the next chip to provide input data. Before forwarding, the DO port is lowered. At this time, the lamp will not receive new data, the built-in RGB chip according to the received 24-bit data after the different duty cycle signal, show different brightness. If the DIN input signal is a RESET signal, the chip will send the received data to display, the chip will receive new data after the end of the signal, after receiving the starting 24-bit data, data will be forwarded through the DO port before the lamp does not receive the RESET code, the RGB brightness remains unchanged. When the low-level RESET code above 200us is received, the RGB chip inside the lamp bead will show different brightness according to the different duty cycle signals generated after the 24-bit data just received.

Data Transmition

Note: D1 is the data sent from MCU and D2, D3, D4 are the data automatically shaped and forwarded by cascaded circuits.

24-bit data structure

Note: Data in high bits are sent first and follow the RGB order.

Timing

T0H	0 code, time of High signal	0.35µs	±150ns
T1H	1 code, time of High signal	1.36µs	±150ns
T0L	0 code, time of Low signal	1.36µs	±150ns
T1L	1 code, time of Low signal	0.35µs	±150ns
RES	RESET code	50µs	\

Notice

• The product in RGB full light (24 for 1), will lead to the lamp bead surface temperature being too high, it is strictly prohibited to feel the temperature by hand.
• The current of this product is close to 2.5a when RGB is fully lit. It is recommended to use A power supply of 5V,3A, or more.
• Since the USB output current of the computer is low, we set the brightness data at RGB555, even if the full light is only about 300mA.
• Also do not set the current too low, if your brightness data is less than 4 bits, part of the light will not be bright.

Hardware Connection

Please take care of the direction when you connect Pico, an USB port is printed to indicate. You can also check the pin of Pico and the LCD board when connecting.
You can connect the display according to the table.

Setup Environment

Please refer to Raspberry Pi's guide: https://www.raspberrypi.org/documentation/pico/getting-started/

Download Demo codes

sudo apt-get install p7zip-full
cd ~
sudo wget https://files.waveshare.com/upload/5/5a/Pico-RGB-LED_code.7z
7z x Pico-RGB-LED_code.7z -o./Pico-RGB-LED_code
cd ~/Pico-RGB-LED_code
cd c/build/

Run the Demo codes

This guide is based on Raspberry Pi.

C Examples

Open a terminal and enter the directory of C codes:

cd ~/Pico-RGB-LED_code/c/

Create a build folder and add SDK:
For example, if the path of SDK is ../../pico-sdk
Then you should create a build and add the path like these:

mkdir build
cd build
export PICO_SDK_PATH=../../pico-sdk

Run cmake.. command to generate the Makefile file:

#Pico
cmake -DPICO_BOARD=pico -DPICO_PLATFORM=rp2040 ..
#Pico2
cmake -DPICO_BOARD=pico2 -DPICO_PLATFORM=rp2350 ..

Run make command to build.

make -j9

After the compilation is complete, the uf2 file will be generated. Press and hold the button on the Pico board, connect the Pico to the USB port of the Raspberry Pi through the Micro USB cable, and release the button. After connecting, the Raspberry Pi will automatically recognize a removable disk (RPI-RP2) and copy the main.uf2 file in the build folder to the recognized removable disk (RPI-RP2).

#Pico
cp main.uf2 /media/pi/RPI-RP2/
#Pico2
cp main.uf2 /media/pi/RP2350

Python Codes

Use in Windows

• 1. Press and hold the BOOTSET button on the Pico board, connect the Pico to the USB port of the computer through the Micro USB cable, and release the button after the computer recognizes a removable hard disk (RPI-RP2).
  
• 2. Copy the rp2-pico-20210418-v1.15.uf2 file in the python directory to the recognized removable disk (RPI-RP2).
  
  • Pico: rp2-pico-20210418-v1.15.uf2
  • Pico 2: rp2-pcio2-20240809-v1.24.0.uf2
• 3. Open Thonny IDE (Note: Use the latest version of Thonny, otherwise there is no Pico support package, the latest version under Windows is v3.3.3).
  
• 4. Click Tools->Settings->Interpreter, and select Pico and the corresponding port as shown in the figure.
  

• 5. File -> Open -> the corresponding .py file, click to run, as shown in the following figure:

This demo provides a simple program...

Run in Raspberry Pi

• 1. The process of flashing the firmware is the same as on Windows, and you have the option of copying the .uf2 format file into the Pico/Pico2 on your PC or Raspberry Pi.
• 2. Open the Thonny IDE on the Raspberry Pi (click on the Raspberry logo -> Programming -> Thonny Python IDE) and you can view the version information at Help -> About Thonny.
• 3. Open the Thonny IDE in Raspberry Pi, update it if it doesn't support Pico
• 4. Configure the port by choosing MicroPython(Raspberry Pi and ttyACM0 port) in Tools -> Options... -> Interpreter

If your Thonny doesn't support Pico, you can update it with the following command:

sudo apt upgrade thonny

• Choose File -> Open...-> python/ and select the corresponding .py file to run the codes.

Install Thonny IDE

In order to facilitate the development of Pico/Pico2 boards using MicroPython on a computer, it is recommended to download the Thonny IDE

• Download Thonny IDE and follow the steps to install, the installation packages are all Windows versions, please refer to Thonny's official website for other versions
  • Thonny IDE official download link
  • Thonny IDE download link
  • Thonny official website
• After installation, the language and motherboard environment need to be configured for the first use. Since we are using Pico/Pico2, pay attention to selecting the Raspberry Pi option for the motherboard environment
  

• Configure MicroPython environment and choose Pico/Pico2 port
  
  • Connect Pico/Pico2 to your computer first, and in the lower right corner of Thonny left-click on the configuration environment option --> select Configture interpreter
  • In the pop-up window, select MicroPython (Raspberry Pi Pico), and choose the corresponding port

Flash Firmware

• Click OK to return to the Thonny main interface, download the corresponding firmware library and burn it to the device, and then click the Stop button to display the current environment in the Shell window
• Note: Flashing the Pico2 firmware provided by Micropython may cause the device to be unrecognized, please use the firmware below or in the package
  • Pico firmware library
  • Pico2 firmware library
• How to download the firmware library for Pico/Pico2 in windows: After holding down the BOOT button and connecting to the computer, release the BOOT button, a removable disk will appear on the computer, copy the firmware library into it
• How to download the firmware library for RP2040/RP2350 in windows: After connecting to the computer, press the BOOT key and the RESET key at the same time, release the RESET key first and then release the BOOT key, a removable disk will appear on the computer, copy the firmware library into it (you can also use the Pico/Pico2 method)
