Any opinions about FREE RTOS? I like a priority scheduling kernel for the product that I about to work on, but are there any significant issues or just annoying features? I am checking out the Free RTOS documentation and other resources. Just curious if anyone has experienced any undocumented issues with it. That's all. Ed

Hi all... I have an application that runs on a PC104 in a RTOS enviroment ( On-time RTOS-32). Now i need to control a dot printer (EPSON LQ300+); to make it i need to write a low level driver to manage LPT port signals. I have no experience in it... ....please help me....

Hi, I often implement an object namespace (visible to the application at run-time) for primary objects managed by the RTOS. This is invaluable in distributed applications as it allows the implementations to be more effectively decoupled (I really can't imagine any other way of supporting such applications that wouldn't be incredibly brittle!). But, the RTOS I'm currently writing doesn'...

Hi, I'm writing another multimedia RTOS and looking through the code I've written that *used* other such beasts in the past (wise move, eh? :> ). It seems like moving zero-copy semantics *formally* into the RTOS's contract should help improve application robustness -- instead of relying on ad-hoc implementations by the developer. Of course, this makes it a bit more cumbersome to pa

Greetings, I am writing my own RTOS, which I intend to use in my projects and license for anyone who would like to use it. At first I will use it in my own projects, so that it achieves a certain level of real-life performance and stability, then release it. The idea is to employ a "classic" embedded RTOS design (single address space, multiple tasks, "hard" RT scheduling) with as much co...

Hi, We're designing a new system using an RTOS. Everyone on the team has worked with an RTOS before, but none of us has ever designed a system. One thing I'm concerned with is we may end up with too many tasks. I reviewed my papers/magazines and searched the web for half a day and didn't get much info. So, for those of you who've been through this before, I have a couple of basic quest...

Dear all, I was going through the explaination for taskRestart() call in the vxworks reference manual.I believe such a feature is available for most of the RTOS in the market.This dicussion talks about vxworks,But it applies in general for any rtos which offers a restarting facility.I am looking for replys from a architecture perspective rather then os specific discussion. Vxworks refer...

Dear Experts, I am interested in knowing how do RTOS implement semaphore objects?It would be helpful if some one could let me know some links or some of your thoughts from your own experience. This is part of my own learning to update myself on what goes beneath when you take a semaphore or give a semaphore in a RTOS. Looking farward for your thoughts and advanced thanks for the s...

Hello, I have one basic doubt about how context switching work in RTOS. Where does the RTOS saves the PC (Program Counter). Is it on the stack of the thread (Then how PC is pushed (i guess only CALL instruction has that power), or can PC be treated as any other register especially in 32bit RISC uC and pushed on stack)? Then, how does the contents of PC changed by RTOS once it is done ...

Starting on my first RTOS project and can't quite see the logic to the interprocess communications. The Zilog RTOS offers message queues, but if the queue is empty the reading process is suspended until something shows up in the queue. Well sorry, that isn't good because my process has multiple things it needs to monitor periodically. It can't get hung on just one message queue. I thought a m...

HI all, I am trying to implement a 8051 based RTOS. Now I have to write a context switch function. I think that , copying all the neccesarry registers without pushing on to the stack works , do you think is this a good idea? Also what stack size is suitable for my RTOS ? (I think 64 byte is ok) If anyone write an 8051 based RTOS can you give me suggestions please? ...

Dear all, I am just curious to know why almost all commercial popular RTOS like RTLINUX,Vxworks work mainly on Micro processor instead of Microcontrollers? AFAIK,I have seen Vxworks work on Boards like Intel x86,powerpc,ARM and all mentioned processor boards instead of real microcontrollers like 8051,68HC series from motorola and so. Why do RTOS prefer microprocessors as compared to microco...
