How to use the Scheduler for a subset of the Application Timers

[Menno]

I have implemented multiple application timers who all automatically use the scheduler because I used:

APP_TIMER_APPSH_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, true);

Nevertheless, I have one specific timer who is very time critical so I don't want to use the scheduler for this timer interrupt. I would like to just execute the code in the timer interrupt itself, while all the other timers are handled by the scheduler. Is this possible?

I read the shedulder tutorial but the only thing I could think of is using app_sched_event_ put() in every interrupt instead of the APP_TIMER_APPSH_INIT(), so basically handling the timer interrupts myself. This way I can select for each timer if I want to use the scheduler or not. Is this the way to go or is there a better way?

Yes, Agree with James, it basically boils down to what you put into scheduler queue and how you are picking it up. So your idea should work perfectly fine. Just DO NOT use APP_TIMER_APPSH_INIT and use instead APP_TIMER_APP_INIT. After this you selectively put callbacks into queue using app_timer_evt_schedule with fetch and decode function app_timer_evt_get
