Efficient Task Scheduling on STM32 Using Cooperative Multitasking
Implementing a lightweight scheduler for real-time applications
By Lester Knight Chaykin
In this blog post, we’ll dive deep into the implementation of a cooperative multitasking scheduler for STM32 microcontrollers. Cooperative multitasking, unlike preemptive multitasking, relies on the tasks themselves to yield control periodically, making it particularly suitable for real-time applications where predictable execution is crucial. We’ll explore the design, implementation, and debugging of a lightweight scheduler capable of managing multiple tasks efficiently. [Read More] -
