Exploring Advanced Interrupt Handling Techniques in Arduino for STM32

Post by ProteasTidbit »

I wanted to start a discussion on advanced interrupt handling techniques for Arduino on STM32 microcontrollers. Interrupts play a crucial role in real-time applications, and mastering them can greatly enhance the performance and efficiency of our projects.

Here are a few topics I'd like to delve into and discuss:geometry dash

- Nested Interrupts: How to implement nested interrupts effectively to prioritize critical tasks while handling multiple interrupt sources.

- Interrupt Prioritization: Techniques for assigning priorities to interrupts based on their importance and ensuring that high-priority interrupts are serviced promptly.

- Interrupt Latency: Strategies for minimizing interrupt latency to achieve faster response times and improve system responsiveness.

- Interrupt Best Practices: Tips and tricks for writing clean and efficient interrupt service routines (ISRs) to avoid common pitfalls and optimize code execution.

- Interrupts and Multitasking: Integrating interrupts with multitasking techniques such as FreeRTOS to create robust and scalable applications.

I'm eager to hear your insights, experiences, and any challenges you've faced when working with interrupts on STM32-based Arduino platforms. Let's share our knowledge and learn from each other to elevate our projects to the next level!

Looking forward to some engaging discussions!

you probably want to read the specific programming manual on your ARM core.

general answers:
1. you can set priorities for different interrupts (there are code in the specific core_cmx.h files) for that.
2. a high priority interrupt (=interrupt with lower priority number) can preempt a low priority interrupt.
3. you can chain interrupts to reduce latency.
4. you want your interrupts to be as quick as possible - no floating point math, no serial printing, ...
5. try not to use interrupts in an rtos, until you know what you are doing.
6. if anything fails, read the programming manual.
