Reply with “Embedded Base” to get more learning materials for free When writing code, we assign an initial value to variables to prevent uncertainty in their initial values due to the <span>compiler</span>. For numeric type variables, they are often initialized to 0, but how should other types of variables, such as <span>char</span>, <span>pointer</span>, etc., be … Read more
Hello everyone, I am the Mixed Content Master. In embedded / microcontroller project development, we often choose a major software framework based on actual conditions: bare-metal systems, front-end and back-end systems, RTOS, Linux, etc. In actual development, choosing the type of software architecture is just the first step. How do the various modules in the … Read more
01Introduction The Ring Buffer (also known as Circular Buffer) is a data structure used to efficiently store and manage data within a fixed-size array. It is particularly suitable for scenarios that require continuous reading and writing of data, such as audio processing, network communication, and real-time data stream processing. Below are the basic concepts, implementation … Read more
Hello everyone, I am the Mixed Content Master. This time we share a commonly used concept/programming model in embedded systems—the Observer Pattern. Overview of the Observer Pattern The Observer Pattern is a behavioral design pattern that focuses on establishing a dynamic subscription-notification mechanism between objects. It defines a one-to-many dependency between objects, so that when … Read more
In the vast field of embedded software development, code comments have always been a controversial topic. Some teams adhere to the belief that “code is documentation,” arguing that excellent code should be self-explanatory; while others advocate for detailed code comments, believing that comments can help other developers understand the logic and intent of the code … Read more
01Introduction: The DSPS (Dialog Serial Port Service) protocol stack is based on the BLE GATT protocol to implement serial data transmission. The core process is divided into four stages: initialization, connection management, data transmission, and low power control. Initialization → Broadcasting/Scanning → Establishing Connection → Data Transmission → Sleep/Wake → Disconnect → Loop 02Detailed Flowchart … Read more
