The CANopen FD Master protocol stack for the STM32437I-EVAL runs on a bit-rate of 500 kBit/s on interface CAN2. Please make sure that:

the CAN cable is connected to CN10
jumper JP3 and JP10 are configured for CAN2

For display of the CANopen network state the example uses the LEDs LD1 (green) and LD3 (red), the symbol COM_LED_SUPPORT is configured to 1.

Board STM32437I-EVAL

The example uses Classical CANopen configuration (COM_FD_SUPPORT = 0) as default.

Prerequisites

The example project can be built if the following programs are installed:

Please make sure that the value of WIN_TOOLCHAIN_PATH (for Windows) or UNIX_TOOLCHAIN_PATH (for macOS / Linux) inside the cmake/toolchain-gcc-<version>.cmake file is equal to the install path of the GNU Arm Embedded Toolchain.

How to build

Create a local build directory and start the build process within this directory. Make sure to pass the correct toolchain (i.e. GNU Arm Embedded Toolchain) to the CMake process via the parameter -DCMAKE_TOOLCHAIN_FILE. The following examples assume a GNU Arm Embedded Toolchain version 13.2.1.

Debug build

mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../../../../../../cmake/module/toolchain-gcc-13.2.1.cmake -DCMAKE_BUILD_TYPE=Debug ..
cmake --build .

Release build

mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../../../../../../cmake/module/toolchain-gcc-13.2.1.cmake -DCMAKE_BUILD_TYPE=MinSizeRel ..
cmake --build .

For compilation in Windows you have to execute following command:

cmake -G"Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=./../../../../../cmake/module//toolchain-gcc-13.2.1.cmake ..

Resource requirements

The amount of Flash and RAM is given under the following conditions:

Symbol	Value
COM_NET_MAX	1
COM_LED_SUPPORT	1
COM_MGR_INT	0
COM_MGR_STD_RCV_FIFO_SIZE	8
COM_MGR_EXT_RCV_FIFO_SIZE	2
COM_SDO_CLN_FIFO_SIZE	4
COM_PDO_MAPPING_ENTRIES	8

All other configuration symbols (refer to com_conf.h) are set to the default value.
