Create a thread that'll run the event queue's dispatch function Create a queue that can hold a maximum of 32 eventsĮventQueue queue(32 * EVENTS_EVENT_SIZE) The simplest way to achieve that is to create a Thread and run the event queue's dispatch method in the thread: #include "mbed.h" You must create and start the event loop manually. An event loop extracts events from a queue and executes them. In Mbed OS, events are pointers to functions (and optionally function arguments).

More generally, the event loop can be used anywhere in a program (not necessarily in an interrupt handler) to defer code execution to a different context. The event loop offers a solution to these issues in the form of an API that can defer execution of code from the interrupt context to the user context.

One of the optional Arm Mbed OS features is an event loop mechanism that you can use to defer the execution of code to a different context.
