what is the download file for compiling mixing c and inline assembly?
Sorry, but your question does not compute.
The tools can create a download file of identical format if your project only contains C. Or if it contains C with inlined assembler. Or if it contains both C and assembler files. Or if it only contains assembler files.
When you get all the way to download files, then we are down to the specific processor instructions the processor should run. It's just a question if the download file is in a raw binary format or some hex format or maybe elf with optional debug information.
Note that inline assembler can seriously hurt your ability to debug the program.
Dupe? http://www.keil.com/forum/60366/ Can you Please read the manual?
If it's a "mixed" file it will still be a .C file, and the linker will still be a .HEX or whatever.
Why do you think any of this would change, do you understand enough assembler for this to be worth doing?
