Smartphones are ubiquitous, but today, Internet of Things (IoT) devices may be more common than smartphones, and many of these devices operate using Bluetooth Low Energy ( BLE ) technology. Whether you are an engineer specializing in IoT, exploring IoT product development opportunities, or simply interested in how IoT works, understanding BLE can be immensely … Read more
1 Introduction With the rapid growth of decentralized structures in manufacturing automation and process automation, the application of field buses is becoming increasingly widespread. It facilitates data transmission between digital and analog input/output modules, intelligent signal devices, and process control devices with PLCs/PCs, dispersing I/O channels to field devices located nearby as required. This reduces … Read more
Profibus-DP Communication Protocol 1. Overview PROFIBUS – DP stands for Decentralized Periphery, which is a type of computer electronic component. It features high speed and low cost, used for communication between device-level control systems and decentralized I/O. It, along with PROFIBUS-PA (Process Automation) and PROFIBUS-FMS (Fieldbus Message Specification), forms the PROFIBUS standard. 2. Basic Information … Read more
Basic Principles of Data Transmission Technology 1. Characteristic Impedance and Delay Characteristics Ideally, due to the in-phase relationship between the voltage and current of the resistive components, the input signal experiences no phase shift when passing through the resistive network, only inherent attenuation. In practical circuits, since cables do not possess purely resistive characteristics but … Read more

Click the blue text to enter ADI, and then click the upper right corner to mark it as a favorite! UART, or Universal Asynchronous Receiver/Transmitter, is one of the most commonly used communication protocols between devices. This article will explain the standard steps that should be followed when using UART as a hardware communication protocol. … Read more
UART stands for Universal Asynchronous Receiver/Transmitter, also known as serial communication. Unlike communication protocols like SPI and I2C, it is a physical circuit within microcontrollers or an independent IC. The main purpose of UART is to send and receive serial data, and its greatest advantage is that it uses only two wires to transmit data … Read more
UART (Universal Asynchronous Receiver/Transmitter) is a widely used serial communication protocol in embedded systems. It supports full-duplex communication, allowing simultaneous data transmission and reception, making it very useful in applications that require bidirectional communication. The working principle of UART is to transmit data bit by bit, meaning each binary bit is transmitted independently through signal … Read more
In the field of C language network programming, the read-write buffer plays a crucial role. It acts as a “transfer station” for data flow, efficiently handling data read and write operations in network communication, optimizing program performance, and enhancing the stability of data transmission. Today, we will delve into how to implement your own read-write … Read more
Imagine this: after a long day at university, you’re on the subway heading home, connected to public Wi-Fi to listen to your favorite podcast, but you notice your phone’s battery is low—below 15%. At this moment, you’re torn between pausing the podcast and wanting to preserve some battery before getting home, so you turn off … Read more
