# Generic AVR Makefile - Adapted for FabTinyStar # Brian Mayton # # 'make' builds the .hex file. # 'make flash' uses the programmer to load it onto the target chip. # 'make fuses' programs the fuse bits on the target chip. # 'make rstdisbl' blows the reset fuse. # 'make clean' removes all autogenerated files. # OBJECTS should list all of the object files for the program (e.g. for each # .c file, list a corresponding .o file here.) APPLICATION just specifies the # name of the hex/elf files, and can be whatever you want. OBJECTS = main.o usbdrv/usbdrv.o usbdrv/oddebug.o usbdrv/usbdrvasm.o APPLICATION = fts_firmware # Set up which MCU you're using, and what programmer, and the clock speed # here.
