It is a lightweight, efficient, and easy-to-use real-time operating system kernel designed specifically for ARM Cortex-M series processors, allowing you to easily control hardware resources and achieve high-performance real-time applications. Lightweight Does Not … Read more
Today, we will discuss interrupt handling in ARM Cortex-M. In embedded systems, interrupts are the core mechanism for achieving real-time responses. Imagine if there were no interrupts: • When a button is pressed, the system might be busy with other tasks and miss the response. • Incoming communication data might be lost due to untimely … Read more
CPU: STM32F429IGT6 For other STM32 chips or other ARM Cortex-M chips, the solution is generally the same. It is recommended to read this article in full before debugging the issues you encounter. 1. Basic Knowledge In ARM Cortex-M series processors, there are several system exceptions dedicated to fault handling. The faults in CM3 can be … Read more
