# MCU name MCU = atmega32u4 # Processor frequency. # This will define a symbol, F_CPU, in all source code files equal to the # processor frequency in Hz. You can then use this symbol in your source code to # calculate timings. Do NOT tack on a 'UL' at the end, this will be done # automatically to create a 32-bit value in your source code. # # This will be an integer division of F_USB below, as it is sourced by # F_USB after it has run through any CPU prescalers. Note that this value # does not *change* the processor frequency - it should merely be updated to # reflect the processor speed set externally so that the code can use accurate # software delays. F_CPU = 16000000 # # LUFA specific # # Target architecture (see library "Board Types" documentation). ARCH = AVR8 # Input clock frequency. # This will define a symbol, F_USB, in all source code files equal to the # input clock frequency (before any prescaling is performed) in Hz. This value may # differ from F_CPU if prescaling is used on the latter, and is required as the # raw input clock is fed directly to the PLL sections of the AVR for high speed # clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL' # at the end, this will be done automatically to create a 32-bit value in your # source code. # # If no clock division is performed on the input clock inside the AVR (via the # CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
