Raspberry Pico: The Complete SDK Overview (Native C/C++,Arduino,MicroPython,CircuitPython)

The Raspberry Pico, or shorthand Pico, is a new microcontroller from the Raspberry Pi foundation. When released early 2021, two frameworks were offered: native C/C++ SDK, and a MicroPython port. About half a year later, two additions became stable: The Arduino framework, a wrapper of the C-SDK in which you work with Arduino commands, and CircuitPython, another embedded version of Python. This article is a comprehensive summary of all available frameworks. You will learn about installation, features, supporting editors and see a blinking LED example for each framework.

C/C+±SDK

The native C/C++ SDK is the original release developed and maintained by the Raspberry Pi foundation.

Installation and usage is covered in the official documentation (PDF). Proper setup can be difficult: You can apply the steps mentioned in the guide, or when you use a Linux OS, use the official one-liner that completely setups the complex toolchain.

There is no standard editor, but the official documentation explain how to customize Visual Studio Code with extensions that support CMake and debugging. For a concrete project setup, I shamelessly self-promote my own getting started kit: pico-project-bootstrap.

Your IDE might look as follows.

The latest release v1.20 has exiting features: Better support for Free RTOS, the real-time Linux system, several update for working with DMA, clocks and mutexes, and even new hardware boards, like the new Pimoroni Pico LiPo, is supported.

The classical blinking LED example looks as follows:

Arduino Framework

Arduino, a name that identifies a family of microcontrollers as well as an IDE, is widely used and known in IOT and robotics project. Arduino boards are typically programmed with C, where the default framework has abstractions for pins, serial input/output, servos etc. Since the release v1.20, you can program your Rasperry Pico with the Arduino framework. This means that the C-SDK functions are wrapped, you use the typical Arduino commands instead.

There are two options to get this working. First, if you are coming from the Arduino world, you can add the Rasperry Pico as a board to your Arduino IDE. Add the Pico Arduino repository to your board manager according to the installation manual. Then, select the appropriate board and you are ready to program.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Download Android SDK Manager and SDK Tools

In this tutorial, we’ll read about the Android SDK Manager. We will see what is SDK manager in Android and why and how it is important for Android. So, SDK stands for Software Development Kit, which is a collection of software tools required. SDK basically helps Android to download tools and recent versions of Android. Every time a new Android version is released, along with it is released an SDK corresponding to it. This SDK must be installed by the developers for the devices.
What is SDK Manager?
A Software development kit is a set of tools required for the development of applications for Android. It also ensures that the progress of App development goes as flat as pancakes. We need SDK irrespective of the language we are using. Android SDK comes wrapped up with the Android Studio these days. An Android SDK separates the tools, platforms and other components into packages. These can be downloaded from the SDK Manager.

How to Run C/C++ in Sublime Text?

C and C++ are the most powerful programming language in the world. Most of the super fast and complex libraries and algorithms are written in C or C++. Most powerful Kernel programs are also written in C. So, there is no way to skip it.

In programming competitions, most programmers prefer to write code in C or C++. Tourist is considered the worlds top programming contestant of all ages who write code in C++.

During programming competitions, programmers prefer to use a lightweight editor to focus on coding and algorithm designing. VimSublime Text, and Notepad++ are the most common editors for us. Apart from the competition, many software developers and professionals love to use Sublime Text just because of its flexibility.

I have discussed the steps we need to complete in this blog post before running a C/C++ code in Sublime Text. We will take the inputs from an input file and print outputs to an output file without using freopen file related functions in C/C++.
