4.4.2 Mechanical Buttons

SAM R34 Xplained Pro Evaluation Kit contains two mechanical buttons:
  • RESET button connected to the SAM R34 reset line
    • When the RESET button is pressed it drives the I/O line to ground
  • Generic user configurable button
    • When the user button is pressed it drives the I/O line to target voltage
Note: There is no pull-up resistor connected to the generic user button. Remember to enable the internal pull up in the SAM R34 to use the button.
