Thonny 4 0 1

Raspberry Pi, please refer to this configuration step.Current Raspberry Pi systems come with Thonny IDE.But if Thonny is not updated to the latest version, there is no Pico support package, and you need to update Thonny to the latest v3.3.3 version.Enable a terminal and enter the following command to update thonny.sudo apt upgrade thonnyOpen Thonny IDE (click Raspberry logo -> Programming -> Thonny Python IDE).Select Tools -> Options... -> Interpreter.Select MicroPython (Raspberry Pi Pico and ttyACM0 port.LED Control DemoConnect the Pico to the computer (without pressing any keys), if you have not flashed MicroPython before, please follow the #Flash Firmware operation.Select Tools -> Options... -> Interpreter.Select Raspberry Pi Pico in the interpreter options (be careful to download the latest version of Thonny, otherwise there is no option).port selection.On the computer, the port is selected as, after connecting to Pico, the COM port recognized by the computer.On the Raspberry Pi, the port is identified as /dev/ttyACM0.Then confirm.After confirmation, you can see that there will be multiple Pico information in the command line interface, and now you can enter the MicroPython program here to control the Pico.Looking at the pin diagram of Pico, we know that the control pin of Pico's on-board LED is GPIO25, here we try to control the on-board LED.Run the following code in sequence in Thonny:>>> from machine import Pin>>> led = Pin(25, Pin.OUT)>>> led.value(1)>>> led.value(0)After running the code in sequence, you can see that the Pico onboard LED lights are turned on and then off.【Note】If you want to know more about the functions of Pico Micropython, you can refer to Pico Python SDK Manual.Hardware ConnectionPlease 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.LCDPicoDescriptionVCCVSYSPower InputGNDGNDGNDMPU.INTGP2INT pin of ICM20948LPS.INTGP3INT pin of LPS22HBSDAGP6SDA pin of I2CSCLGP7SCL pin of I2CFSYNCGP22FSYNC pin of ICM20948Connect the expansion boardEnvironment BuildingPlease refer to Here.Download the examplesOpen a Raspberry Pi terminal and run the following commands:sudo apt-get install p7zip-fullcd ~sudo wget x Pico-Kit-B-code.7z -o./Pico-Kit-B-codecd ~/Pico-Kit-B-codecd c/build/How to useC ExampleGo to the directory of the C example and build it.cd ~/Pico-Kit-B-code/c/Create the build folder and enter it. add the SDK:../../pico-sdk #should be the path of the SDK according to the actual situation.We have created the build folder in the example, you can just enter it.cd buildexport PICO_SDK_PATH=../../pico-sdk(Note: Please check if you set the correct path of SDK, it may be different for different users)Run cmake to generate the Makefilecmake ..Run make to build the example, it will take minutes.make -j9uf2 is generated after building.Press and hold the button of the Pico board, and then connect the Pico

Thonny IDE should automatically detect the port, but you may need to select it manually (e.g., COM3 on Windows or /dev/ttyACM0 on Linux).On Thonny IDE, navigate to the Tools Manage packages on the Thonny IDE.Search “DIYables-MicroPython-Button”, then find the Button library created by DIYables.Click on DIYables-MicroPython-Button, then click Install button to install Button library.Copy the above code and paste it to the Thonny IDE's editor.Save the script to your Raspberry Pi Pico by:Click the Save button, or use Ctrl+S keys.In the save dialog, you will see two sections: This computer and Raspberry Pi Pico. Select Raspberry Pi PicoSave the file as main.pyClick the green Run button (or press F5) to run the script. The script will execute.Press, hold, then release the limit switch while checking

Python has become one of the most popular programming languages due to its simplicity and versatility. For beginners, choosing the right Integrated Development Environment (IDE) can significantly enhance the learning experience. One such IDE that stands out for its user-friendly interface and educational features is Thonny. This article will provide an overview of Thonny, its features, and how to get started with it.What is Thonny?Thonny is an open-source Python IDE designed specifically for beginners. Developed at the University of Tartu, Estonia, it aims to provide a simple and intuitive environment for learning Python programming. Thonny is particularly beneficial for those who are new to coding, as it offers features that help users understand the language’s concepts without overwhelming them with complex functionalities.Key Features of ThonnySimple Interface: Thonny’s interface is clean and straightforward, making it easy for beginners to navigate. The layout includes a code editor, a shell for executing commands, and a variable explorer.Built-in Python Shell: The integrated shell allows users to execute Python commands interactively, providing immediate feedback and facilitating experimentation.Variable Explorer: This feature helps users visualize the variables in their program, showing their values and types, which is crucial for understanding how data is manipulated in Python.Step-through Debugger: Thonny includes a simple debugger that allows users to step through their code line by line, making it easier to identify and fix errors.Easy Installation: Thonny can be installed quickly on various operating systems, including Windows, macOS, and Linux, making it accessible to a wide audience.Getting Started with ThonnyInstallationTo install Thonny, follow these steps:Visit the official Thonny website at thonny.org.Download the installer for your operating system.Run the installer and follow the on-screen instructions to complete the installation.Creating Your First Python ProgramOnce Thonny is installed, you can start coding. Here’s how to create a simple Python program:Open Thonny.In the code editor,

To your Raspberry Pi or PC by USB cable, then release the button. Then copy the main.uf2 file which is saved in the build folder to the Pico (It should be recognized as a portable drive, which is named RPI-RP2).Python exampleWork with windows PC1. Press and hold the BOOTSET button of Pico, and connect the Pico to your PC by USB cable. Release the button if the Pico is recognized as a portable drive.2. Copy the rp2-pico-20210205-unstable-v1.14-8-g1f800cac3.uf2 from the Python directory to the Pico.3. Open Thonny IDE (Note: Please use the newest version).4. Click Tools -> Options -> Interpreter and choose the Port of Pico (you can check it in the Device Manager).5.
