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
