CMSIS DSP library support (arm_math.h)

Software Development

I haven’t done it with wildcarding, but there are three variables that need to be edited/set to work add the CMSIS files.
I was only using a few things when I was experimenting so the C_SOURCES list is fairly short.
However, as many files as needed can be added manually. It should also be able to be set with a wildcard similar to above.

This can sneak by until you hit the compiler error:

ASM_SOURCES = \
$(LIBDAISY_DIR)/Drivers/CMSIS/DSP/Source/TransformFunctions/arm_bitreversal2.s

here are a few of the c sources

C_SOURCES = \
$(LIBDAISY_DIR)/Drivers/CMSIS/DSP/Source/TransformFunctions/arm_rfft_fast_f32.c \
$(LIBDAISY_DIR)/Drivers/CMSIS/DSP/Source/TransformFunctions/arm_rfft_fast_init_f32.c \
$(LIBDAISY_DIR)/Drivers/CMSIS/DSP/Source/CommonTables/arm_common_tables.c \
$(LIBDAISY_DIR)/Drivers/CMSIS/DSP/Source/CommonTables/arm_const_structs.c \
$(LIBDAISY_DIR)/Drivers/CMSIS/DSP/Source/TransformFunctions/arm_cfft_f32.c \
$(LIBDAISY_DIR)/Drivers/CMSIS/DSP/Source/TransformFunctions/arm_bitreversal.c \
$(LIBDAISY_DIR)/Drivers/CMSIS/DSP/Source/TransformFunctions/arm_cfft_radix8_f32.c

and lastly the Include folder has to be added for all of the header files

C_INCLUDES += \
-I$(LIBDAISY_DIR)/Drivers/CMSIS/DSP/Include

These can be done in any order as long as they’re above the final include statement.

Hope that helps!
