Yesterday we introduced what a Raspberry Pi is, and today we've brought it home. How do we play with it? I'll guide you step by step. Wait, just having a Raspberry Pi is not enough; you also need a micro SD card, at least 16GB, as small capacity ones are hard to find these days. Once you have the memory card, you can burn a system onto it (we're talking about Raspbian here), and the Raspberry Pi will boot up.

This tutorial series aims to transform the Raspberry Pi into an industrial controller using CODESYS. The previous article introduced how to boot the Raspberry Pi and start an SSH connection. Today, we will discuss how to install CODESYS Runtime on the Raspberry Pi.

CODESYS Runtime is a software system that can transform the current operating system into an industrial controller, thus also known as a soft PLC. To install CODESYS

Chapter 1 Introduction

1. Introduction to ARM Cortex-M3 Processor

The CM3 processor core is the central processing unit (CPU) of microcontrollers. A complete MCU based on CM3 requires many other components. After chip manufacturers obtain authorization to use the CM3 processor core, they can incorporate the CM3 core into their silicon designs, adding memory, peripherals, I/O, and other functional blocks. Different manufacturers will design microcontrollers with different configurations, including unique memory capacities, types, peripherals, etc. This book focuses on the processor core

When facing an unknown thing, we should first clarify what it "is", then understand what it can be used for, and finally learn why it exists.

What is Arduino?

To know is to know, to not know is to "Baidu" it.

Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform, which includes hardware (various models of Arduino boards) and software (Arduino IDE), developed by a European team in the winter of 2005. (Quoted from Baidu Encyclopedia)

Arduino is a set of electronic

ARM processors are widely used - from sensors to servers.

ARM is the industry's leading microprocessor technology provider, offering the broadest range of microprocessor cores to meet performance, power, and cost requirements across nearly all application markets.

ARM's technology combines a vibrant ecosystem with over 1000 partners, providing chips, development tools, and software, with over 90 billion processors deployed. ARM's technology is at the core of the computing and connectivity revolution, changing how people
