As you mentioned Keil have a project.lst includes C program and assembly but i couldnt use it for compile to hex.(Do you understand me or not?) j.majd@engineer.com
"What part of 'becuase i have to' do you not understand?" That bit's clear - what isn't clear is what it applies to! Is it "because I have to give him assembler," or is it "because I have to give him something he won't understand." My reading of the original questions is that the requirement is to keep the 'C' source secret, while still allowing this untrustworthy "customer" to build his project - so it's "because I have to give him something he won't understand." A Library neets that requirement admirably - So that is a direct answer to the question as I read it.
