Hello readers, I hope you all are doing great. This is the second tutorial of the Raspberry Pi programming series. In our previous tutorial, we discussed the basic features and hardware architecture of Raspberry Pi Pico.

In this tutorial, we will discuss the various available development environments for programming the Raspberry Pi Pico. Later, in this tutorial, we will also discuss the installation of Visual Studio Code for Pi Pico programming.

RP2040 supports multiple programming languages like C/C++, Circuit python, and MicroPython cross-platform development environments. Raspberry Pi Pico module consists of a built-in UF2 bootloader enabling programs to be loaded by drag and drop and floating point routines are baked into the chip to achieve ultra-fast performance.

There are multiple development environments to program a Raspberry Pi Pico board like Visual Studio Code, Thonny Python IDE and Arduino IDE etc.

We need to download and install some tools before installing the Visual Studio Code for programming Raspberry Pi Pico which includes:

  1. CMake
  2. ARM GCC embedded tool-chain package
  3. Python
  4. Git open source project
  5. Build tools for VS code

CMake

Fig. CMake

CMake is an open-source system developed/designed to fulfill the need of powerful cross-platform build environment which is responsible for managing the build process in a compiler independent manner and in an OS (operating system. It is designed to work in conjunction with the native build environment.

CMake is responsible for generating a build environment for compiling a source code, building executables, creating libraries and generating wrappers.

It also supports dynamic and static library builds. It can handle complex hierarchies and applications dependent on several libraries. CMake can also handle projects with multiple toolkits or libraries, where each library is further having multiple directories.

CMake is open-source tool which is easy to use and also having a simple yet extensible design which can be extended (as per the requirements) to support new features.

Git

Git is an open-source tool responsible for code management. The main purpose of using Git is to track the changes in the source code or any set of files, which helps multiple developers work together on non-linear development. In simple words, we can say that Git makes a team of people or developers work together and that is too using common/same files. Toptal is a marketplace for top coders.

Downloading Pico SDK

Once all the necessary tools (mentioned above) are successfully installed, we can download the Raspberry Pi Pico SDK and respective examples.

Before downloading the Pico SDK and Pico examples, we need to create a folder or directory to save the SDK and pico examples. So, we are creating a folder “RPi Pico” in C:\ drive.

  • Open the command prompt.
  • Next task is to create a new new directory in ‘C’ drive using “mkdir” command to download and save the SDK and pico examples.
  • To download/clone the raspberry pi Pico SDK type : “git clone –b master https://github.com/respberrypi/pico-sdk.git in the command prompt and press enter.
  • Make sure your system is connected to internet.

  • After this, the CMake tool will initialize building the Makefiles for all projects.
  • From the bottom blue menu tab, by selecting the build button, you can build other projects as well.
  • So now we are all set to upload a program into raspberry pi pico.

Before writing a program for Raspberry Pi Pico make sure you have all the necessary hardware components along with the software and compilers (installed) required to program the Pico board.

Components required to program Raspberry Pi Pico are:

  • The first thing required is a Micro-USB Cable, which allows the user to connect it to a computer or a Raspberry Pi for programming and powering up the Pico board.
  • Next component is the development environment required to compile and upload the program into the Raspberry Pi Pico development.
  • If you need to interface a peripheral with your Pico board using a breadboard then, you also need a set of Pico Headers.

Conclusion

This concludes the installation procedure for Visual Studio Code in Windows ( for Raspberry Pi Pico programming) which includes the installation of various tools and compilers necessary for programming Raspberry Pi Pico.

In our next tutorial, we will discuss the installation procedure of Python Thonny IDE for programming the Raspberry Pi Pico. We will also continue the programming part with Python Thonny IDE with MicroPython programming language.

I hope you found this tutorial of some help and also hope to see you soon with a new tutorial.
