    How do you change structure

    When I want to change int in function I pass pointer to int so int will change #include<stdio.h> void foo ( int *ptr ) { *ptr = 10; } int main () { int a = 1; foo (&a); printf("%d", a); return 0; } I am trying to understand how we change the structure in function int...

    How tasks are broken down into smaller task's

    Agreed This project can be done with RTOS and without RTOS. I take the situation that we have to do this project with RTOS. Now we come back to the original question, we have to split the task for the RTOS. Can you offer any help in understanding how the tasks would be divided for this application

    How tasks are broken down into smaller task's

    @Harald Kapp as per your advice i choose a real time system https://www.electronics-notes.com/articles/test-methods/spectrum-analyzer/realtime-spectrum-analyser.php I have broken tasks into three tasks Sampling FFT processing Display Any idea How all tasks will execute in real-time

    How tasks are broken down into smaller task's

    A real-Time operating system may be single or multitasking. What I'm trying to find out is how tasks are broken down into smaller tasks for real-time operating systems. I see that tasks execute on a priority basis. A high-priority task always runs first. I see some tasks have hard timing...
