When developping an application in C for ST7 micros, you have to choose between 2 C compiler : Cosmic or MetroWerks.

Now I am at this step, I have to make this choice.

Can you please give me your feedback on this?

1- Have you noticed some differences between the 2 C compilers? (optimization, size of the code, timings, prices, options)

2- What features are included in one compiler and is not included in the other?

3- What are the advantages and drawbacks for each compiler?

Thank you very much for your help.

Best Regards

I would recommend cosmic out of the two.

Cosmic gives slightly better optimisation as well as the choice of either using a software or hardware stack - metrowerks only has a software stack.

I also think cosmic is slightly cheaper, it was anyway.

Don't bother with zap (save the money), just use Visual Debug.

Is there anyboday else who had experienced using the 2 compilers? and that have noticed differences between them? (in term of generated code size and speed, speacila optimizations).

Thank you

Hello

I am FAE of STMicroelectronics and i am getting this question all the time .

What i am learning from my customers that all the programmer like the Cosmic but the Metrowerks give more optimaize code .

I have tried both and finally choosed the cosmic !

I like the Cosmic thing, highly optimized towards code efficiency

even their maths libs are impressive

but their editor (idea) is pure BS.

Yes thats true thats a difficult choice to make, it could be a good idea to discuss all the differences between these 2 compilers.

Compared to cosmic, Metrowerks is the right choice to take care of the codesize and it has some good compiler options to reduce both ROM,RAM.

( It all depends on the way in which the program has been written )
