Understanding and Utilizing Hook Functions in RTOS
In many operating systems, there exists a type of API function interface called: HOOK functions.
For example, HOOK functions can be found in desktop operating systems like Windows, as well as in real-time operating systems such as µC/OS and FreeRTOS.
Let’s discuss HOOK functions in the context of µC/OS, including what they are and their uses.
What are Hook Functions?
Hook functions, also known as HOOK functions, are functions that are called internally by the operating system.
If HOOKs are enabled, the operating system will
Open Source GUI for Embedded Systems
When QT was acquired for 600 million dollars, it was shocking! Is the graphical interface really that valuable?

In embedded software development, we inevitably encounter the concept of priority. Mastering the concept of priority is crucial for designing a good software system.
The main content of this note includes the following aspects:
1. Interrupt priority
2. Task priority in the operating system
3. Handling of equal priority
4. Interrupt nesting
Today, Osprey will discuss some secrets using the familiar STM32F103 platform.
First, let's start with a variable increment in a
LiteOS Raspberry Pi Porting Guide (Part 2)
Porting Introduction
For embedded devices, due to the large differences in chip models and peripherals, and limited resources, IoT operating systems cannot adapt and integrate all drivers like Windows/Linux. Therefore, typically, only part of the chips/development boards are adapted first. To run the operating system
