Hi All
Apologies if this is the wrong sub board...
From my understanding of the SDK, you can have up to 3 os_tasks to do different things.
The vast majority of examples only ever seem to set up 1 task with a delay and nothing else.
Other functionality is then delivered by 1-shot or repeating timers or interrrupts.
What purpose do the system_os_task and system_os_post serve ? It's not an RTOS and it seems (from my tests) that even if multiple system_os_tasks are defined and then posted to, only one task ever seems to run.
Thanks

Granted it does seem quite an obscure set of semantics. My best guess is that it allows us to register a function which will be called at some time in the future (as quickly as possible I imagine) after we return control to the OS.

Now ... why we might not want to call the logic of the task function then and there ... I don't know. Perhaps it allows us to register an "anonymous" function where "somebody else" registered it ... but that's getting more far fetched.
