* Added a MS/TP zero-config (automatically choose an unused MAC address) using an algorithm that starts with MAC=64 and waits for a random number of PFM (minimum of 8 plus modulo 64) before attempting to choose a MAC sequentially from 64..127. The confirmation uses a 128-bit UUID with the MSTP Test Request frame. The modifications are in src/bacnet/datalink/mstp.c and src/bacnet/datalink/dlmstp.c modules enabling any device to use zero-config if enabled. A working demonstration is in the ports/stm32f4xx for the NUCLEO board. Complete unit testing is included. Options include lurking forever (wait for a router or another master node before joining) or lurking for a minimum time (enables self forming automatic MAC addressing device nodes).
Win32 ports for BACnet
This directory contains a demo program that compiles with a Win32 compiler. It was tested with the free MinGW32 MSYS2 GCC compiler and the (free) Microsoft Visual Studio Community Edition
Building with Makefile under MinGW32
Note: Building for 64-bit with MinGW64 requires extra runtimes, whereas building for 32-bit as Win32 doesn't require any other files for the EXE to work in any version of Windows.
-
MSYS2 installation is (from powershell):
c:> winget install --id=MSYS2.MSYS2 -e
-
Start MSYS shell, and install MinGW32.
$ pacman -Syu mingw-w64-i686-toolchain
-
Edit ~/.bashrc file and add:
alias make=mingw32-make.exe
-
Exit MSYS.
-
Start MSYS profile for MinGW32.
-
Verify MSYS profile:
$ uname
MINGW32_NT-10.0-19045
-
Verify GCC is targeting i686:
$ gcc -dumpmachine
i686-w64-mingw32
-
Verify make is built for Windows32:
make --version
Built for Windows32
Building and running with Microsoft Visual Studio
- Obtain the (free) Microsoft Visual Studio Community Edition, or use your professional version. Currently tested to MSVC 2022
- Open solution file ports/win32/Microsoft Visual Studio/bacnet-stack.sln
- Set startup project to be the desired application project, e.g. "server"
- In the active project properties, debugging, set command line to desired DeviceID
- In active project properties, debugging, set environment variables as appropriate, e.g. BACNET_IFACE=10.59.2.1 BACNET_IP_PORT=53004
- Compile & run
