How to use RTOS and how it can trigger functions or interrupts?

[btminzon]

Hi people

I'm new using RTOS. I have questions: First of all, how can i use RTOS? for example, FreeRTOS, or BOS for MSP430, etc... Do i need to use more than one firmware running in uProcessor, or just one running under RTOS? in case using one software (firmware), how RTOS can trigger my functions, or interrupts? its very obscure to me untill now...Thanks a lot your help

beste regards

You build your program with the rtos.
Your program may consist of several tasks or functions.
The rtos manages the switching between the tasks and the communications between them.

general rtos concepts

you could have sw interrupts, like timer, and hw interrupt, like press a button.

best rtos books

RTOS as name suggest is a real time operating system. Apart from its real time nature, it functions as normal OS(Windows,Linux).
OS is a abstraction to the low level system functionality. Depends on the OS architecture you can create a task,process,thread.

Lets take a hypothetical example, say you have RTOS X, and it supports only one process(task), and supports n threads. Now you can write a program which uses the API provided by OS to perform some operation. Compile it, link it with RTOS and burn in on the hardware,

Now there is only one user process is running and thread you have created, But depends on the architecture of the OS, there may be some other system processes running to do memory managment, thread management, interrupt handling etc.

A good starting point to understand how the things work is FreeRTOS.
Go to www.freertos.org page and have a look at the tutes.

general question about rtos

Regarding books and RTOS:

One that just came out, centered around PIC but has a solid chapter on RTOS:
https://www.elsevierdirect.com/product.jsp?lid=0&iid=73&sid=0&isbn=9780750686112

And one that is coming in ~3months....
https://www.amazon.com/Building-Real-Time-Operating-System/dp/0750683791/

The Labrosse book is still the standard. But remember, there's no substitute for spending some quality time with the code.
