Hi,
I want to use inline assembly code in a thumb compiled file! And I'm using ADS1.2! Thanks a lot!

ADS does not support embedded assembler, it was added in RVCT.

I don't believe you can do this. I'd suggest calling a function from a seperate assembler file.

I don't believe ADS1.2 supports inline assembly when targetting Thumb code;
you could try embedded C,e .g:

__asm myfunc(int r0, int r1) { ADDS r0,r0,r1; BX lr; }

Very nice post with a ton of informative information. I really appreciate the fact that you approach these topics from a stand point of knowledge and information
instead of the typical "I think" mentality that you see so much on the internet these days.
