UCOSII & Coocox OS on SAM3U-EK

Fri Sep 04, 2009 11:11 am

Yesterday,I port UCOSII to SAM3U-EK borad,and then develop a MP3 programmer base on UCOSII.
There also has a MP3 programmer base on Coocox OS,you can get the source code from http://www.coocox.org/EXAMPLE/ATMEL_Keil_ARMCC.htm.

The two MP3 programmer both runs very well.

For what is Coocox OS,you can visit http://www.coocox.org.

Absolutely amazing. You have been busy. How have you had time two write 2 MP3 players while simultaniously spamming nearly all the forums (including the FreeRTOS forum) with this nonsense? Actually 3, in a different post you said you had done it with the ARM RTOS.

I'm sure your spamming (from Embest in China, by the way) does you a lot of good. Its a pity, but then there is no justice in the world.

Richard

Now I have uploaded the software package to prove that I really ported the MP3 player for UCOSII. If you are interested in it, you can download to have a look.

Besides, I think I should not compare with other OS which may be inappropriate. So I have deleted the relative contents.

In addition, we have ported the mp3 player for some other OS. If you are interested in it, you can contact me by an email. Of course, it does not include freertos. In my opinion, the architecture of freertos is too complex and it is too difficult to learn so that it is not suitable for Cortex-M3. If you do not agree my view, I can also delete those sentences.

Finally, if there is some unjustice, please point it out instead of talking nonsnce. What's more, please don't guess wild. Otherwise, you will bear legal responsibility.

We all provide free and open rtos for users, and I don’t know why you have so great response on it.

Looks like he called your bluff by posting the source code. He is probably right about the performance of his RTOS, probably blows away FreeRTOS, but then, what RTOS doesn't? At least he publishes his performance whereas:

clause 2
"FreeRTOS may not be used for any competitive or comparative purpose, including the publication of any form of run time or compile time metric, without the express permission of Real Time Engineers Ltd."

You accuse the competition of spamming, but you don't allow competitive analysis? Why? Fear?
