From: Rick North on 26 Feb 2006 16:01 Great replies, Thank you all for sharing. I like the Pete Fenelon msg about true hard RTOS and looked around more and found one in Sweden. Sierra by Realfast, http://www.realfast.se/RFIPP/products/sierra/sierra.shtml I surely will have a closer look at uCos and QNX. Again, Thank you all it was my first post in this newsgroup and I think I will monitor it more closely Cheers, Rick Rick North skrev: > Hi All, > > I have tried to get some information about RTOS from different > suppliers, but I find it hard to cut trough the marketing and sales > pitch persons.

Check out the PDFs found there and if it is not enough info drop me an email bastian.schick@<company>.com But be aware: It is direct-message-passing, no global variables and _no_ semaphores :-) but with 6 system-calls you can build 80% of your application ! -- 42Bastian Do not email to bastian42(a)yahoo.com, it's a spam-only account :-) Use <same-name>@monlynx.de instead !

You bought from the wrong company :-) Tip for evaluation an RTOS: Send a stupid support question and check how long it takes that you get an answer. If support is bad during evaluation it won't be better when you've bought. -- 42Bastian Do not email to bastian42(a)yahoo.com, it's a spam-only account :-) Use <same-name>@monlynx.de instead ! |
