CC = avr-gcc

## Options common to compile, link and assembly rules
COMMON = -mmcu=$(MCU)
COMMON += -DF_CPU=8000000UL

## Compile options common for all C compilation units.
CFLAGS = $(COMMON) $(CEXTRA)
CFLAGS += -D AVRGCC -Wall -gdwarf-2  -Os -fsigned-char
CFLAGS += -MD -MP -MT $(*F).o -MF dep/$(@F).d

## Assembly specific flags
ASMFLAGS = $(COMMON)
ASMFLAGS += -x assembler-with-cpp -Wa,-gdwarf-2

## Linker flags
LDFLAGS = $(COMMON)
LDFLAGS += -Wl,-Map=$(PROJECT).map,--cref

## Intel Hex file production flags

## Other dependencies
## In cygwin the /dep folder causes make to fail after the initial make.
## $make CYG=1 allows cleans and makes based on .c dependencies (but not .h)
