![]() In this tutorial we’re going to switch the Pico firmware from C/C++ to MicroPython and create our first program, which flashes the LED on the board. However, there’s a more beginner-friendly method: MicroPython, a port of the Python programming language designed specifically for microcontrollers. The C/C++ SDK is an extremely flexible and powerful way to interact with your Raspberry Pi Pico. Raspberry Pi Pico is set up, by default, for use with the C/C++ Software Development Kit (SDK). Program Raspberry Pi Pico with MicroPython Make sure to read, and bookmark, these new Raspberry Pi Pico and 2040 data sheets. Makers looking to explore the C/C++ SDK should download the Pico C/C++ SDK documentation. Get Started with MicroPython on Raspberry Pi Pico is available now from Raspberry Pi Press. As well as learning how to use Raspberry Pi Pico’s pins as inputs and outputs, you’ll build a simple game, measure temperatures, save and load data to your Pico’s file system, and even make a burglar alarm for your room. Get Started with MicroPython on Raspberry Pi Picoįor more physical computing projects to try on your Raspberry Pi Pico, grab a copy of the new book, Get Started with MicroPython on Raspberry Pi Pico. Additionally, the C/C++ SDK provides higher-level libraries for dealing with timers, USB, synchronisation, and multicore programming, along with additional high-level functionality built using PIO such as audio.īeginners looking to get started with the MicroPython port should start with the Raspberry Pi Pico Python SDK documentation and be sure to pick up a copy of Getting Started with MicroPython on Raspberry Pi Pico. Meanwhile, the C/C++ SDK is fine-tuned to RP2040 and has all the headers, libraries, and build systems necessary to write programs in C, C++, or assembly language. Programs written for other MicroPython-compatible microcontroller boards will work on Raspberry Pi Pico, and vice versa – sometimes needing minor modification for different features between boards – giving Raspberry Pi Pico a healthy library of projects and tutorials beyond those developed by Raspberry Pi itself. This was meant as a simplified ‘getting started’ tutorial with the Pico, and the first of a series dedicated to working with the Raspberry Pi Pico microcontroller.You can pick up a Raspberry Pi Pico from just $4 / £3.60, or free with the latest edition of HackSpace magazine. The basics of getting started with MicroPython and the Pico microcontroller were first introduced, followed by some simple hardware tests with general purpose inputs and outputs (GPIOs) and an RGB LED. In this tutorial, the Raspberry Pi Pico was explored using Thonny, a Python IDE already installed on the general distribution of the Raspberry Pi operating system (Raspberry Pi OS). Using only a Raspberry Pi 4, the Pico microcontroller can be programmed to run MicroPython and harness its numerous peripherals: I2C, SPI, UART, PWM, analog-to-digital conversion, etc. It is a direct rival in some respects to competitive open-source and ‘maker’ electronics companies like Arduino, Espressif, PIC, Teensy, and others. The Raspberry Pi Pico was introduced as a new MicroPython-enabled microcontroller produced by the Raspberry Pi Foundation. An RGB LED will be used to demonstrate general purpose input/output of the Pico microcontroller. From start to finish - this tutorial helps users run their first custom MicroPython script on the Pico in just a few minutes. A Raspberry Pi 4 computer is ideal for interfacing with the Pico, which can be used to prepare, debug, and program the Pico. The focus on MicroPython, as opposed to C/C++, minimizes the confusion and time required to get started with the Pico. One particular draw of the Pico is its compatibility with MicroPython, which is chosen as the programming tool for this project. One of the innovations of the Pico is the dual-core processor, which permits multiprocessing at clock rates up to 133 MHz. The board is just 21mm x 51mm in size, making it ideal for applications that require low-profile designs. The Pico shares many of the capabilities of common Arduino boards including: analog-to-digital conversion (12-bit ADC), UART, SPI, I2C, PWM, among others. The Raspberry Pi Pico was recently released by the Raspberry Pi Foundation as a competitive microcontroller in the open-source electronics sphere.
