Convention: This article is based on freeRTOSv202212.01. Defining a Task Task scheduling involves the “tasks” that need to be managed, so we need to first understand what a “task” looks like. An independent task must consider the following points: 1. The system must recognize and manage this task, so the task needs an identification card … Read more
1. Concept and Classification of Memory In computing systems, memory is used to store variables and intermediate data. The system memory can be divided into two types: Internal Storage Space (RAM): Typically refers to Random Access Memory, which allows fast data access and random access, but data is lost when power is off. External Storage … Read more

Introduction Recently, I wrote an article titled “Installing .NET Core 3.0 Runtime and SDK on Raspberry Pi 4”, followed by subsequent articles on “Auto-starting .NET Core 3.0 Environment on Raspberry Pi”, “Nginx Configuration for Internal Access to Raspberry Pi 4 ASP.NET Core 3.0 Website”, and “Tianpai Magic | .NET Core 3.0 + Azure Remotely Turning … Read more
Programming is a term that tells computers how to work. Through programming, we can easily manipulate any technology. Just like everyone has their own language or specific dialect in certain regions, computers or advanced technologies also have specific languages, and its name is “programming.” Those who engage in programming are called programmers. However, merely learning … Read more
QP/C, a lightweight and open source real-time embedded framework (RTEF), provides powerful tools for building modern embedded software. It is based on the active object (Actor) model and has won widespread acclaim in the embedded systems development field due to its efficiency, safety, and ease of use. This article will delve into the key features, … Read more
