Finding a compiled Hex file for the arduino

Jack W8TEE has provided directions on how find a compiled hex file:

1. Go to your Preferences settings (File –> Preferences) and check “Set verbose output during” and check “compilation”
2. Compile the program. Do not upload as that erases all temporary files, including the hex file. In other words, just click on the
check mark icon that appears below the File menu option.
3. Scroll down the long list of output your compile generated until you see: “Linking everything together…” followed by a series of
lines with path and file names. The hex file for you program will be one of them. Just use that path name to find the hex file.

While you’re there, use a text editor to open the *.lst file. It shows a blending of C and assembler generated by the compiler. It’s an interesting way to find if one way of writing a piece of code is “better” (i.e., faster execution, or perhaps using less memory) than an alternative way.
