Hi all Being new to the SDCC mailing list I would like to find out if anybody = knows about a proper free, open source, pre-emptive multitasking = scheduler that has been tested together with the SDCC C compiler. =20 If there are no proper free shcedulers available I would appreciate = suggestions for an affordable commercial scheduler that is good value = for money and that has been tested with the SDCC compiler. Any help will be appreciated regards Henko |

Untested with the SDCC: The Intel iDCX51 is a realtime multitasking preemptive operating system, and released to the public domain. It should work with any compiler, just make sure you use the right registers etc. Regards, Pieter Hoeben ______________________________________________________________________ Hoeben Electronics Phone : +31 6 51590081 Ronkert 44 Fax : +31 13 5096025 5094 EW Lage Mierde Private : +31 13 5096024 The Netherlands E-mail : in...@ho... http://www.hoeben.com <mailto:in...@ho...> ______________________________________________________________________ |

Hi Henko, Normally somebody needs to know for which microcontroller you need an RTOS, but there is also uCOS. The source code comes together with the book MicroC/OS-II and it is highly portable for various microcontrollers. The book expains the internals of the RTOS and how to port it. For further informations take a look at http://www.ucos-ii.com/ or contact me. The book is approx $70 and it's worth it. There is another book called Embedded Systems Building Blocks 2nc edition, which contains useful APIs once you have uCOS running. Like this you would have a microcontroller independent framework. I am also very interested in porting this to SDCC. If there are other people interested in this work, let's do it together. regards, Robert -----Original Message----- From: sdc...@li...

Hi Robert, I am interested in porting ucos to sdcc,I have started to do smth,but at the moment I am thinking twice which way to take,and I wold like to explain: ucos-ii is great and works fine,I have the book and I have read it and experiment smth.; but for 8051 I still ask myself if it is not too complicated and huge;and I think that there are needed many optimizations to make for '51. On the other side,I have the first version which appeared in Embeeded Journal and seems to me to be much shorter and more easy to adapt to '51. The main problem is how fast can the tasks be switched - as Rene Vooberg states in his port to 8052,only 10 per second - for my immediate need is very slow -,and only porting to '251 seems to be something good,but sdcc does not support '251... Can you tell me what intentions do you have? I would like to cooperate,and i will be ready to do it after 15 august,when i will finished my vacation.

Hi Ioan, I totally agree, that uCOS might be a little heavy on an 8051, but this depends strongly on what you want to do with it and which 8051 you are planning to use. You know that it is highly configurable and if you just want a scheduler I think it's working just fine. My vision is, like to have SDCC for several microcontrollers to have a common RTOS for several microcontrollers. Of course there might be faster RTOSes (there is one from Intel, which is written in Assembly) optimised or a specific microcontroller architecture, but I want to have an RTOS, where I can write applications on top of it and I have to freedom to use a different microcontroller if the one I'm using is not sufficient with minimum effort. So let's first port it to the 8051 and the other micros supported by SDCC and after some benchmarking let's decide if we go on with it or not. regards, Robert > -----Original Message----- > From: sdc...@li... > [mailto:sdc...@li...]On Behalf Of Ioan Petrescu > Sent: Freitag, 07.

I all... I'm interested in a free RTOS for 8051 family (i supose that I will use the new DS80C390 from dallas) for our university projects here... I recently used for the first time the RTX51 (with a SAB80C535) and i loved it :)))) But this one have a big problem... its not free, and i don't know how much it costs the licence for our university... I already passed on the intel web site searching for the iDCX51 RTOS, but i found nothing :((( Can you tell were i can get that iDCX51 for take a look to it?
