-# common make targets for compiling fx2 firmware
-#
-# In your Makefile, define:
-# SOURCES: list of c files to compile
-# A51_SOURCES: list of any a51 files.
-# DEPS: list of any depedancies (like auto-generated header files) that need
-# generated prior to compiling. You must provide the target definition
-# for any DEPS you define.
-# BASENAME: name of your firmware file, i.e., myfirmware, but not myfirmware.c
-#
-# Leave these alone or redefine as necessary to customize firmware.
-# (Redefine after including this makefile)
-# VID vendor id
-# PID product id
-# LIBS optional additional libraries to link with the firmware.
-# SDCC build/link options
-# CODE_SIZE: Default --code-size 0x3c00
-# XRAM_SIZE: Default --xram-size 0x0200
-# XRAM_LOC: Default --xram-loc 0x3c00
-# BUILDDIR: build directory (default build)
-# These two can be changed to be blank if no device descriptor is being used.
-# DSCR_AREA: Default -Wl"-b DSCR_AREA=0x3e00"
-# INT2JT: Default -Wl"-b INT2JT=0x3f00"
-#
-# Provided targets:
-#
-# default target: creates $(BASENAME).ihx
-# bix: creates $(BASENAME).bix
-# iic: creates $(BASENAME).iic
-# load: uses fx2load to load firmware.bix onto the development board
-# (You can customize VID/PID if you need to load the firmware onto a device that has different vendor and product id
-# The default is 0x04b4, 0x8613
-# clean: delete all the temp files.
-#
-#
-#

-# The sdcc 8051 assembler binary has/had different names.
