Polling API - (polling API)
The polling API is used to wait concurrently for any one of multiple conditions to be met.
1. Concepts - (Concepts)
The main functions of the polling API are k_poll() , it is conceptually very similar to the POSIX poll() function, except that it operates on kernel objects rather th ...

RT-Thread version: 4.0.5 MCU model: STM32F103RCT6 (ARM Cortex-M3 kernel)
1 Synchronization and Mutual Exclusion
First add a few concepts:
Execution Unit: Determined by the current hardware platform and the operating system it runs. For RT-Thread and STM32, the execution units are threads and interruptsCritical Zone: Multiple execut ...

Pre episode review
Single chip microcomputer HLK-W801 transplanted Nes simulator (I) I've finished the transplantation of the program. Today, I'll try the key operation. At least I can jump and eat a mushroom
For the identification of keys on w801, I use an omni-directional key keyboard I used before, The keys are collected ...

STM32F103 Mini transplant RT thread nano
Introduction to RT thread nano
RT thread nano is a minimalist version of hard real-time kernel. It is developed by C language, adopts object-oriented programming thinking and has a good code style. It is a tailorable, preemptive real-time multitasking RTOS. Its memory resources are very small, and ...

The primary role of RTOS is to switch threads, just like interrupt processing logic. After interrupt, handle other things. After processing, return to normal and continue execution.
RT thread kernel code is used here to verify
The main functions of thread switching are written in assembly language. I think we will ...
