Im looking for a real time operating system that can be used on a TI MSP430F2274...

Why?

What are u using?

I would imagine that the majority use no OS at all...?

 Hi Andy, from time to time I wish use some form of OS on MSP, but nothing appear to be simply usable and sometimes cost too much and not least no time to learn.

 Salvo from pumpkins has a free release but i hope is so limited to be used on and first usable version cost 900Us$. There where other OSes  complex like uCOSII but also licensing is a nightmare and system requirement limit usage to hi end devices.

 I try again the original question someone has something to recommend or share experience with some resource limited RTOS preferably open source?

 Me too.

Hi Gerald,

In my experience, the majority of people using MSP430s use no operating system at all, particularly if they are using the smaller/simpler parts. Before jumping into an RTOS, I would try to analyze if it's going to help your application or not, be it in ease of development, performance, etc. For most MSP projects, it is usually simpler to go without the RTOS, especially if you are using a part with limited code space.

However, TI does provide an RTOS called SYS/BIOS that has support for MSP430. This RTOS is free and if you have ccsv4 or ccsv5, you should already have it. There is more information here: http://www.ti.com/tool/sysbios and on this wiki page: http://processors.wiki.ti.com/index.php/SYS/BIOS_for_the_MSP430

This wiki page also speaks to using different RTOS with MSP430 in general: http://processors.wiki.ti.com/index.php/MSP430_Real_Time_Operating_Systems_Overview

 Hi Katie, you win a question about sysbios:

 what about memory footprint, performance impact and which devices support?

 About Salvo is usable also on low end devices, did you know about benefit and performance impact?

 Also on a non low footprint I wrote my own scheduler due to no time to learn or choose an RTOS, what I wish and hope same for Gerald is to ear from someone that real use it.

 Thank you
