AVR®: Switching Between Programming and Power Options with Xplained Mini

 In this video:

  • Alternate between ISP and debugWIRE interface (toggling the power after using SPI to enable the Debug Wire Enable (DWEN) Fuse).
  • Switch to ISP from debugWIRE: While debugging, selecting 'Disable debugWIRE and close' now allows to select ISP.
  • Open the Programming dialog box in ISP mode to read the fuse settings.
  • Program the Clout Out (CKOUT) fuse to put the AVR® MCU clock out on the COUT pin.
  • Run the ATmega328P Xplained Mini at:
    • 5 V - reading a clock frequency of 16 MHz.
    • 3 V - reading a clock frequency of 8 MHz.
  • Understand speed vs. voltage of the AVR MCU from the datasheet.
