Notice

RP2040-Plus uses the same RP2040 chip as the Raspberry Pi Pico, and it is compatible with the Raspberry Pi Pico, in this case, most of the accessories and codes can be used with the RP2040-LCD-0.96 as well.

Software Setup

Please follow the guides of Raspberry Pi to install and set up Pico for the Pico.

For easy use, we recommend you use the Thonny tool.

  • Thonny website
  • Please set the Thonny development environment to be RaspberryPi when setting.
Pico-R3-Tonny1.png
  • Configure the Micrpython environment and select the Pico port.
    • First, connect the Raspberry Pi Pico to your computer, left click on the Configure environment option in the lower right corner of the Thonny --> Select Configure interpreter.
    • In the pop-up window, select MicroPython (Raspberry Pi Pico), and select the corresponding port.

  • Click OK and then back to Thonny, download the firmware library to the Pico. Then click Stop, and you can see the current environment in the Shell window.
  • How to download the firmware library for Pico in Windows: Press and hold the BOOT key and connect to the computer, then release the BOOT key, a removable disk will appear on the computer, and copy the firmware library into it.
  • How to download firmware library for RP2040 in Windows: After connecting to the computer, press the BOOT key and RESET key at the same time, release the RESET key, 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 method).

# print the number of seconds since reset:
lcd.printout("Waveshare") #Print the string
lcd.setCursor(0, 1) #Move the cursor to second row.
lcd.printout("Hello,World!")#Print the string
lcd.setRGB(rgb1[0],rgb1[1],rgb1[2]); #Set the back light

Introduction

MicroPython Series

C/C++ Series

For C/C++, it is recommended to use Pico VS Code for development. This is a Microsoft Visual Studio Code extension designed to make it easier for you to create, develop, and debug projects for the Raspberry Pi Pico series development board. Whether you are a beginner or an experienced professional, this tool can help you confidently and easily develop Pico. Below we will introduce how to install and use the extension.

  • Official website tutorial: https://www.raspberrypi.com/news/pico-vscode-extension/.
  • This tutorial is applicable to Raspberry Pi Pico, Pico2, and our company's RP2040 and RP2350 series development boards.
  • The development environment defaults to Windows as an example. For other environments, please refer to the official website tutorial for installation.

Arduino IDE Series

Install Arduino IDE

  1. Download the Arduino IDE installation package from Arduino website.

Upload Demo At the First Time

  1. Press and hold the BOOTSET button on the Pico board, connect the Pico to the USB port of the computer via the Micro USB cable, and release the button when the computer recognizes a removable hard drive (RPI-RP2).
    Pico Get Start.gif
  2. Download the demo from #Resource, open the D1-LED.ino under arduino\PWM\D1-LED path.
  3. Click Tools -> Port, remember the existing COM, do not need to click this COM (different computers show different COM, remember the existing COM on your computer).
    UGV1 doenload02EN.png
  4. Connect the driver board to the computer with a USB cable, then click Tools -> Ports, select uf2 Board for the first connection, and after the upload is complete, connecting again will result in an additional COM port.
    UGV1 doenload03EN.png
  5. Click Tools -> Board -> Raspberry Pi Pico/RP2040 -> Raspberry Pi Pico.
    Pico Get Start02.png
  6. After setting, click the right arrow to upload.

FAQ

 Answer:

1. The pin that sets the input state must be initialized to pull high or low.
2. Replace the USB cable to see if there is a problem with the USB cable used.

{{{5}}}


 Answer:

The official firmware has not been updated and is still written with 2M RAM; just use the following corresponding firmware:
4M: 4M MicroPython firmware
16M: 16M MicroPython firmware

{{{5}}}


 Answer:

It cannot be updated through a C++ program, you can try to use Arduino ide to develop or use our debugger (RP2040 GEEK).
