Introduction to the ros_arduino_bridge Open Source Package

This tutorial introduces the ros_arduino_bridge open source package. If you are creating a ROS mobile robot based on Arduino, this package provides a complete software solution. The package not only controls the motors to drive the chassis but also includes data acquisition from ultrasonic sensors and infrared distance sensors, as well as various general analog and digital signal sensors. It can control the output of digital signals and supports PWM servo control.

Explore the ADALM-PLUTO SDR with Digi-Key: Funpack Edition 5

Funpack is a year-long "Play to Win" event initiated by Hard禾 Academy in collaboration with Digi-Key. Each month, we will introduce a top-tier semiconductor manufacturer's development board/instrument kit. If you can play with it according to the specified goals within a month, you can receive substantial rewards.

Finally, the troublesome year of 2020 is over. In 2021, the fifth edition of Funpack kicks off with the powerful ADI ADALM-PLUTO SDR as our handheld RF lab!

With the new year comes new opportunities.

Understanding Arduino: An Introduction to Open Source Electronics

First, let's review some background information (of course, you can skip this part).

Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform. It includes hardware (various models of Arduino boards) and software (Arduino IDE). It was developed by a European team during the winter of 2005, including members such as Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, David Mellis, and Nicholas Zambetti.

It is built on an open-source simple I/O interface and has a development environment similar to Java

Weekend Arduino Training: Experience the Real Thing!

This weekend, Sosi will take you to experience the real Arduino!

The course is open to all members of Sosi and moderately open to the public. The main purpose is to let many students who have not been exposed to hardware quickly get in touch with it, generate interest in hardware, and understand the basic knowledge of microcontrollers.

So the question arises, what is Arduino?

Many students may have this question,

and need a comprehensive and accurate answer.

Not only you, but many users

Intel and Arm Diversify Their Focus at Computex 2018

We have traditionally viewed Intel and Arm as the dominant players in the PC and server markets, and the mobile application domain, respectively. Although these companies have attempted to cross into each other's territories in the past, they have not been particularly successful. However, at the 2018 Computex conference, "diversification" became the main theme.

Traditionally, Intel is a major player in the PC and server solutions market, but this time it

The Turbulent Future of Arm: Can RISC-V Take on the Challenge?

According to reports from Electronic Enthusiasts Network (by Zhou Kaiyang), there have been numerous reports claiming that Nvidia's exclusive acquisition negotiations for Arm have entered the final stages, with related parties stating that the transaction could be completed as early as late summer this year. As an architecture that supplies billions of chips to the market each year, this news has raised concerns about Arm's position, and its open-source competitor RISC-V has begun to emerge in people's minds.
As the dominant

Understanding the Differences Between Huawei, Apple, Samsung, and Qualcomm in the ARM Ecosystem

For a long time, there has been a strong call to break the monopoly of Wintel and AA systems and establish a Chinese version of Wintel. It is also urged that successful domestic enterprises must bravely take on heavy responsibilities and fulfill social responsibilities.

However, many netizens are skeptical and cite examples of Apple, Qualcomm, and Samsung relying on ARM, believing that "Apple, Samsung, and Qualcomm all belong to the ARM camp, so why can't Huawei?"

Let’s discuss the differences

ARM and TSMC Collaborate on 7nm Technology for Future iPhones

Tencent Digital News (Translated by: Duo Duo) According to foreign media reports, Apple’s chip foundry TSMC is collaborating with ARM to develop a 7nm manufacturing process, which is likely to be seen in future products such as the iPhone and iPad.
According to registration documents, this technology will enter the early production phase as early as 2017, but it

The Myth that x86 Can’t Make Low-Power CPUs: Arm Remains Silent

In the past, low power consumption and high computing power processors were clearly distinct. For example, Arm, which originated from Acorn, was fundamentally based on low power consumption — in the early years of the ARM instruction set development, it was hardly considered to compete with high-performance instruction sets like x86 or POWER. To the average person, these were simply two different industries.
In the low-power domain, even when

Understanding Embedded Microprocessors in Embedded Systems

1. Basic Structure of Embedded Microprocessors
(1) An embedded hardware system generally consists of an embedded microprocessor, memory, and input/output components.
(2) The embedded microprocessor is the core of the embedded hardware system and typically consists of three main parts: control unit, arithmetic logic unit, and registers:
A. Control Unit: Responsible for basic operations such as fetching instructions, decoding, and retrieving data, and sending major control commands.
B. Arithmetic Logic Unit: Primarily processes numerical data and performs logical operations.
C. Registers: Used for temporarily storing
