From the project
Versaloon Software Framework -- a tiny preemptive-capable event-driven incremental software framework for embedded systems
Full name of VSF is "Versaloon Software Framework". VSF is an open-source software framework for embedded applications based on Apache2 license. VSF includes hal, a pre-emptive multi-thread kernel, services and components. VSF is implemented by C language with object-oriented programming methods(PLOOC).
- event-driven architecture, sleep if no event occurred, lower-power naturally - in pre-emptive mode, task switch is implemented by hardware swi(software interrupt), priority of task is the priority of the swi. - pre-emptive scheduling for tasks with different priority, collaborative…
