Re: The Best RTOS
Hello,
You need to define 'best' before you ask a question like this. What platform are you using, and what development tools? Do you want to spend money on it? Generally the free RTOSs are more difficult to use, but the commercial ones cost a lot of money. Some compilers come with an included rtos which may be enough for your needs. Some posters here are giving you OSs which are for 16/32 bit processors 'RTEMS,' is one example.
The best advice I've seen here is for uCOS II, because as you build it, you can read about it, and gain understanding of how to use it well. That being said, picOS18, or freertos, is probably worth looking into. SALVO has a demo version, that is probably the quickest to get up and running.
Most likely, you can get by with a simple scheduler, which you can write yourself. RTOS is well suited to apps where timing is critical: auto-pilots, and medical equipment, where a failure in timing can spell disaster. For almost all hobby projects, a scheduler is enough.
Just my two cents,
Robert
