+# 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.
