I am using the IAR compiler. It has an include (h) file and a linker control (xcl) file for each AVR. But not the mega48 because that was introduced after this compiler version. I could not find a download, so I asked IAR. They said that I would need to pay to upgrade my compiler. They are working on a quote. Yes, I know that I can generate the files myself, but I am disappointed. :(
Can anyone tell me how the other compilers handle this? If a new chip comes out after you buy the compiler, how do they support it?
