The USB audio application requires the following hardware:
To program the device you can use the following methods:
Please refer to the hardware user guide of the board you are using to see how to program the
device using these different methods.
Please refer to FLIP
through the USB interface.
Note:
• AVR USB evaluation board (ATEVK527)
• AVR USB microcontroller
• USB cable (Standard A to Mini B)
• PC running on Windows
• headset
• The JTAG interface using the JTAGICE mkII
• The SPI interface using the AVRISP mkII and JTAGICE mkII
• The USB interface thanks to the factory DFU bootloader and FLIP
• The parallel programming using the STK
host
1. FLIP is software provided by atmel to allow the user to program the Atmel devices through the
USB interface (No external hardware required) thanks to the factory DFU bootloader.
