Just a friendly tip here: You are coming across as very much "DO MY PROJECT FOR ME! NOW!" with the questions you pose. And when people give you the right answer, which is typically to show how you can get all the information in the world about solving your issues, you reject these answers. The same thing pretty much happened in the thread you started a while ago when you attempted to run some Basic interpreted on an Arduino.
Asking questions (any kind, even stupid ones) is fine, but do some research first and show what you have done and ask questions based off of that. Downloading a firmware does not qualify as research in my book. Had you bothered to research MCU programming at all, you would probably have figured this out yourself without ever asking.
