How to use KidsPico?

getting started with Arduino IDE

WINDOWS

Download Arduino IDE

When you get KidsIOT, you need to download Arduino IDE and driver firstly.

You could download Arduino IDE from the official website:

https://www.arduino.cc/, click the *SOFTWARE* on the browse bar to enter download page, as shown below:

There are various versions of IDE for Arduino. Just download a version compatible with your system. Here we will show you how to download and install the windows version of Arduino IDE.

You can choose between the Installer (.exe) and the Zip packages. We suggest you use the first one that installs directly everything you need to use the Arduino Software (IDE), including the drivers. With the Zip package you need to install the drivers manually. The Zip file is also useful if you want to create a portable installation.

You just need to click JUST DOWNLOAD.

Install Pico board

1. Open Arduino IDE，then tap Tools→Board→Boards Manager…

   

2. In the search bar, type in Pico and search to install Arduino Mbed OS RP2040 Boards.

   

3. If there is a security interface, please click “Install” .

   

   

4. Tap Close.

   

Upload Pico firmware that is compatible with Arduino.

1. Disconnect Raspberry Pi Pico to computer. Press and hold the white button(BOOTSEL) on Raspberry Pi Pico until the board is linked to PC. (Always remember to hold the button until connection is finished, otherwise firmware fails to be downloaded. )

   

2. Open Arduino IDE，Click File → Examples → 01.Basics → Blink.

   

3. Click Tools → Board → Arduino Mbed OS RP2040 Boards → Raspberry Pi Pico.

   

4. Upload Sketch Blink to Pico.

   

   Then you will see below:

   

   The indicator on Pico board will blink.

   

   Click Tools → Port → COMx(Raspberry Pi Pico).

   In COMx, X varies from computers. So please select the correct COM port. In our demostration, the port is COM15.

   

   NOTE

   A. Uploading Sketch via Arduino to Pico for the first time, no port selection required. Yet, every time after that, you need to check whether the port is selected; otherwise the download may fail.

   B. Sometimes, Pico board may not work due to loss of firmware. At this moment, please upload firmware again.

MAC

Download Arduino IDE

The operation steps are similar to Windows systems.

Success：You have successfully installed the Pico Boards on Arduino IDE.

onboard OLED display

kidsPico is equipped with a 128x64 pixel OLED screen. Next, we will use the Arduino code to learn how to use this screen.

Installing an OLED Display Library

An OLED LCD display is integrated on the KisUno development board, the SSD1306 controller in the OLED display has flexible but complex drivers. To use the SSD1306 controller, extensive knowledge of memory addressing is required. Fortunately, the SSD1306 library can be used to hide the complexities of the SSD1306 controller, allowing us to control the display with simple commands.

To install the library, navigate to Sketch > Include Library > Manage Libraries… Wait for the Library Manager to download the library index and update the list of installed libraries.

Filter your search by typing ‘adafruit ssd1306’. There should be a few entries. Look for SSD1306. Click on that entry and then choose Install.

This SSD1306 library is a hardware-specific library for low-level functions. To display graphics primitives such as points, lines, circles, and rectangles, it must be paired with the Adafruit GFX Library. Install this library as well.

Internally, the SSD1306 library makes use of the Adafruit Bus IO Library. So, look for Adafruit BusIO in the library manager and install it as well.

Here’s a simple code that will do the following:

#include <Wire.h>

Getting started with microPython

Windows System

For Windows 10

Software download link：Thonny software official website

When the mouse touches the location indicated by the arrow, the official Windows download version will appear.

MAC System

Please refer to the Windows system.

Software Installation

Thonny application installation supports two installation methods：

• Install Thonny+Python bundle package

  The essence of this method is to package the Python environment and Thonny together, which can be installed and used with one click. It is recommended for novices to use this method. There are two ways to install the bundled package:

  • Installer installation

    

  • No installation required

    

• Install Thonny

  Thonny applications essentially exist in the form of python packages. When users already have a python environment, they can install Thonny separately through pip install thonny. This approach is more suitable for developers.

  

Please download the corresponding version of the compressed package according to your needs.

Installer Installation

Please select the corresponding program to download according to your operating system. Here we take the installation program Installer with 64-bit Python 3.10 in the 64bit Windows 10 environment as an example.
