# Hey Emacs, this is a -*- makefile -*- # AVR-GCC Makefile template, derived from the WinAVR template (which # is public domain), believed to be neutral to any flavor of "make" # (GNU make, BSD make, SysV make) # # Adaptations by Jon Langseth # This modified template is placed in the public domain like the original. # #AVRDUDE_PROGRAMMER = usbasp AVRDUDE_PROGRAMMER = usbtiny AVRDUDE_PORT = usb AVRDUDE_BL_PROGRAMMER = arduino AVRDUDE_BL_PORT = COM3 AVRDUDE_BL_SPEED = 115200 # Target name and MCU setup ------------------------------------------------- TARGET = fbosd MCU = atmega328p # Processor frequency. # This will define a symbol, F_CPU, in all source code files equal to the # processor frequency. 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. # Typical values are: # F_CPU = 1000000 # F_CPU = 1843200 # F_CPU = 2000000 # F_CPU = 3686400 # F_CPU = 4000000 # F_CPU = 7372800 # F_CPU = 8000000 # F_CPU = 11059200 # F_CPU = 14745600 # F_CPU = 16000000 # F_CPU = 18432000 # F_CPU = 20000000 # Default settings: #F_CPU = 1000000 # Fuse-bits.
