Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
  4. Difference between a crystal, and a crystal oscillatorhttps://www.avrfreaks.net/comment...
  5. When your question is resolved, mark the solution: https://www.avrfreaks.net/comment...

Send me your email address and I'll email over my hourly rate for contract development work. Payment will be 50% up front; 25% on delivery of working code and 25% on delivery of full documentation. My preferred payment method is Paypal.

At #52 this appears to have split off into a new thread:

So I'm going to lock this now to prevent cross posting accidents.
