# open62541 Architecture Support
|
|
|
|
This folder contains all the architecture-specific code for different operating systems.
|
|
The arch-specific code covers:
|
|
|
|
- System clock
|
|
- EventLoop (Networking, Interrupt handling (optional))
|
|
|
|
Currently open62541 supports
|
|
|
|
- Windows
|
|
- POSIX (Linux, BSD, Mac, etc.)
|
|
|
|
Previously (until v1.3) there was additional support for:
|
|
|
|
- freeRTOS
|
|
- vxWorks
|
|
- WEC7
|
|
- eCos
|
|
|
|
We strive to recover support for these.
|
|
The main effort of porting is forking the EventLoop implementation.
|
|
|
|
## Adding new architectures
|
|
|
|
To port to a new architecture you should follow these steps:
|
|
|
|
1. Create a ua_clock.c file that implements the following functions defined in open62541/types.h:
|
|
|
|
* UA_DateTime UA_DateTime_now(void);
|
|
|
|
* UA_Int64 UA_DateTime_localTimeUtcOffset(void);
|
|
|
|
* UA_DateTime UA_DateTime_nowMonotonic(void);
|
|
|
|
2. Fork the EventLoop code (the default is POSIX) and adjust to your architecture
|
|
|
|
3. Add your architecture to the list in /include/open62541/config.h.in
|
|
|
|
4. Add the architecture and the new files to /CMakeLists.txt
|
|
|
|
You can also use a custom architecture implementation outside of the library build.
|
|
For that, set UA_ARCHITECTURE=none in the cmake setting.
|
|
Then no architecture-specific code will be included in the open62541 library itself.
|
|
You have to link in your custom clock and EventLoop implementation only for the final binary.
