Need help: What timer to use?


mbo

Question

Hello guys,

I am using Zybo Z7-10 and want to use a timer which polls e.g. every 100ms by starting a task in freertos.

What is the best way to implement such timer?

Do I need to use XScu_Timer or Global Timer or Watchdog Timer

Thanks,
Mirco

Hi @jpeyron

Yes, I have looked at these pages but I dont really understand what a Watchdog Timer is and what it is for.

Is my understanding correct that ISR increments ticks which is a single step in RTOS and switches tasks between those ticks?

Is there a good tutorial how to implement ISR and use it with several tasks?

Thanks,
Mirco
