Re: [Bacnet-developers] Having problem porting STM32F4xx

[Steve K. <st...@ka...>]

Hello Emre Can Kirtorun,

You didn't mention which compiler or IDE you are using, so I'm guessing you
are not using the example code in ports/stm32f4xx folder as-is.
The IAR project file uses some defines to tune RAM usage, and there are
more settings in src/bacnet/config.h
<https://sourceforge.net/p/bacnet/src/ci/master/tree/src/bacnet/config.h>
file that can be overridden from their defaults, or just make your own
config file.

IAR:
                    <state>NDEBUG</state>
                    <state>USE_STDPERIPH_DRIVER</state>
                    <state>STM32F4XX</state>
                    <state>BACDL_MSTP</state>
                    <state>MAX_APDU=480</state>
                    <state>BIG_ENDIAN=0</state>
                    <state>MAX_TSM_TRANSACTIONS=1</state>

GCC Makefile:

BACNET_FLAGS = -DBACDL_MSTP=1
BACNET_FLAGS += -DBACAPP_ALL
BACNET_FLAGS += -DMAX_APDU=480
BACNET_FLAGS += -DBIG_ENDIAN=0
BACNET_FLAGS += -DMAX_TSM_TRANSACTIONS=0
BACNET_FLAGS += -DMAX_CHARACTER_STRING_BYTES=64
BACNET_FLAGS += -DMAX_OCTET_STRING_BYTES=64
# if called from root Makefile, PRINT was already defined
BACNET_FLAGS += -UPRINT_ENABLED
BACNET_FLAGS += -DPRINT_ENABLED=0

Probably MAX_TSM_TRANSACTIONS needs to be lowered, since the default is 255.

Best regards,

Steve
