}
To do:
• Build the project/solution (F7)
• Program the application into the target device using Start Without Debugging (Ctrl+Alt+F5)
• Switch to Data Visualizer to see the results
Important: Because the previous example prescaled the clock to 8 MHz/64, the ISP programming clock
must be set to less than 32 kHz to be below 1/4 of the main clock.
Important: Remember to disable on-board power on the Xplained Mini.
