ATtiny85 20MHz Internal Clock
Here is a new tutorial from technoblogy.com on how to run ATtiny85 with internal 20MHz clock. The ATtiny85 is rated at a maximum clock speed of 20MHz at 4.5 – 5.5V. For some applications it would be nice to get the maximum speed without needing to buy a 20MHz crystal, or tie up two...
