Hello All,
I am looking for real time operating system which is widely use in the embedded device? I heard about Windows CE, Vxworks and FreeRTOS. I am new bee in this, Could you please suggest widely use RTOS with good support available(even its fine if it is nor free)?
Thanks for your help and time.

Thanks
Parag
 

learning micrium's micro-C OS-II will be useful as it it very simple and can be used with many IDE available like IAR workbench, keil -3 etc. and are used in safety critical applications also... wince is mostly for mobile platform and dont have any other application much.. vx works is good but only if you have licenced version.. 30 day demo version has lot of features disabled....
 

HI ckshivaram,
Thanks for reply, I can buy vxWorks license. I am working on STM3210EVAL in Ride 7 IDE, can we import vxWorks in it or I need to shift on different platform or IDE?
Also I think micrium's micro-C OS-II don't work on Ride7 and need to shift to keil IDE. Is it?
One more important question, if we compare micrium's micro-C OS-II and VxWork OS for any embedded application, which one is widely use and better?
 

you need to shift the platform... you can shift to keil micro vision 3 for micrium OS......

both are widely used, but micrium is easy to learn and all RTOs concepts are same irrespective of any RTOS........
 

Thanks. But to compile the code on Keil, we have some limitation i think we can compile and debug till 32 Kb that means we cannt use keil if code is more than 32 Kb? IS that the case?
 

Yes, but for learning purpose it should be good enough... 32K is too big to develop simple RTOS application using ADC interrupts serial port etc...
 

Hello

A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time application requests.

A key characteristic of an RTOS is the level of its consistency concerning the amount of time it takes to accept and complete an application's task..A hard real-time operating system has less jitter than a soft real-time operating system. The chief design goal is not high throughput, but rather a guarantee of a soft or hard performance category. An RTOS that can usually or generally meet a deadline is a soft real-time OS, but if it can meet a deadline deterministically it is a hard real-time OS...

Basically UCOS-ii is a free RTOS.You can learn it is easily
