Hi!
I would be really interested in getting a new arm compiler (ASM), I want to program directly through assembly. Could someone (support), finded a compiler I could used? Instead of the normal arduino IDE & compiler. What about a arm compiler? I could mixed C and ASM?
I would really appreciate it!
Sorry for bad english
You can mix C and ASM for the ARM with the Arduino IDE and compiler. It seems to fit your requirements already. What is it about the Arduino IDE that you are trying to avoid.
Personally, I like Eclipse. But I am still using the Arduino toolchain. It works as well as anything else IMHO.
You will be hard pressed to produce better assembler code than the compiler.

Not sure but ATMEL might have what you want.
