 25 May 2008 1:11 where to begin learning RTOS |
|
|
|
I just graduated with a BS Electrical and Computer Engineering Technology degree where I picked up an interest in embedded programming but apparently my degree isn't going to get me any where considering we didn't cover topics of Object Oriented programming or RTOS. Almost every single job requirement for embedded software engineer requires RTOS and a few of them require object oriented programming. We did spend class time with microchip PIC 16F877A's across three semesters in C using the CCS C complier.
I am looking at learning RTOS on my own and get a little experience with it but I do not know where to begin because my budget is fairly small.
I was thinking about going to a ARM 7 but I am having a hard time finding a cheap development system for it.
Any suggestions would be appreciated for a processor/board and maybe reference material (books, pdf's, websites).
Thanks

Vxworks and QNX.
You can buy MCB2100 from keil or order at NXP. They have ARM7 complete kit available for learners. cost not so much

| Olimex boards are good, too. You may also check Embedded Artists boards

HAI,
if you know basiscs of operating system concepts u can easily learn RTOS also because almost all UNIX(GPOS) and VXWORKS(RTOS) commands are similar with little difference.

Yes and no.
Many of the APIs can be similar (start timer, send a message, get a semaphore) but the major difference between an RTOS and a non-real-time OS is the scheduler behavior & implementation.
Things like priority inheritance, interrupt latency, preemption, scheduling strategy and other mechanisms give the RTOS a more deterministic behavior in a real-time setting.
At the application level, if you abstract out enough, most OSs can be thought of as "similar" in that they allow multiple tasks/processes/threads to run concurrently and communicate with one another. But as they say, "the devil is in the details".
