|
|
The NUCLEO-F429ZI platform includes the following peripherals:
|
|
|
|
1) USB ST-Link
|
|
|
|
2) Ethernet
|
|
|
|
3) Arduino Uno V3 compatible RS485 shield (DFR0259)

### Building this Project
|
|
|
|
#### IAR EWARM Project
|
|
|
|
There is an IAR EWARM project bacnet.ewp that can be used to build the project.
|
|
|
|
#### GNU Makefile
|
|
|
|
There is a GNU Makefile that uses arm-none-eabi-gcc to build the project.
|
|
It also includes recipes for openocd or stlink, and gdb or ddd for debugging.
|
|
|
|
This is used in the continuous integration pipeline to validate the build
|
|
is not broken. The Makefile is called from an Ubuntu image container
|
|
after installing the necesary tools:
|
|
|
|
sudo apt-get update -qq
|
|
sudo apt-get install -qq build-essential
|
|
sudo apt-get install -qq gcc-arm-none-eabi
|
|
sudo apt-get install -qq libnewlib-arm-none-eabi
|
|
|
|
For debugging, install these tools:
|
|
|
|
sudo apt-get update -qq
|
|
sudo apt-get install -qq openocd gdb-multiarch
|
|
|
|
##### Shield option
|
|
|
|
If, instead of the DFR0259 shield for RS485, the build is intended for the
|
|
linksprite shield, `make SHIELD=linksprite` can be used.
|
|
|
|
#### CMake & Visual Studio Code
|
|
|
|
There is a CMakeLists.txt file that enables building the project with the
|
|
tools that CMake can find. It is useful under Visual Studio Code editor
|
|
with the CMake Tools extension for quickly configuring the build environment,
|
|
choosing a cross-compiler, and building.
|
|
|
|
For Visual Studio Code debugging, add the Cortex-Debug extension, and configure
|
|
its settings for the specific OS and path of the tools. For Windows using
|
|
MinGW64:
|
|
|
|
"cortex-debug.armToolchainPath.windows": "C:/msys64/mingw64/bin",
|
|
"cortex-debug.gdbPath.windows": "C:/msys64/mingw64/bin/gdb-multiarch.exe",
|
|
"cortex-debug.objdumpPath.windows": "C:/msys64/mingw64/bin/objdump.exe",
|
|
"cortex-debug.openocdPath.windows": "C:/msys64/mingw64/bin/openocd.exe",
|
|
|
|
To add the build and debug tools to MinGW64 environment:
|
|
|
|
pacman --noconfirm -S mingw-w64-x86_64-arm-none-eabi-gcc
|
|
pacman --noconfirm -S mingw-w64-x86_64-openocd
|
|
pacman --noconfirm -S mingw-w64-x86_64-gdb-multiarch
