This is the easiest way of doing it and the documentation only focus on this method. Generate the open6254.h and open6254.c files with the freeRTOSLWIP architecture and then put these files in your project in your IDE that you’re using for compiling. This method can be hard to do because you need to specify the include files and some other configurations. Select the cross compiler in CMake, set the flags needed for compilation (different for each microcontroller so it can be difficult) and then run make in the folder and the library should be generated. There are two main ways to build open62541 for freeRTOS + LwIP: This documentation assumes that you have a basic example using LwIP and freeRTOS that works fine, and you only want to add an OPC UA task to it. If you have any doubts, please first check the discussion there. The configured maximum message size that is preallocatedĬredits to documentation is based on the discussion of the PR. The RAM requirements of a server are mostly due to the following settings: Information to the binary that is only used for human-readable logging and
UA_ENABLE_TYPEDESCRIPTION and UA_ENABLE_STATUSCODE_DESCRIPTIONS add static Last, logging messages take up a lot of space in the binary and might not be
Examples for this are Subscriptions or encrypted Third, some features might not be needed and can be disabled to reduce theīinary footprint. Setting this option can reduce the binary size by Second, setting UA_NAMESPACE_ZERO to MINIMAL reduces the size of theīuiltin information model. Second, the binary size can be reduced by removingįeatures via the build-flags described above. This sets the compiler flags to minimize the binary size. The following options influence the ROM requirements:įirst, in CMake, the build type can be set to CMAKE_BUILD_TYPE=MinSizeRel. That require less than 100kB of RAM and ROM. With open2541, it is possible to configure minimal servers The size of the generated binary can be reduced considerably by adjusting theīuild configuration. UA_FILE_NS0 is used to specify the file for NS0 generation from namespace0 folder.
DEBIAN INSTALL CMAKE FULL
Use the full NS0 instead of a minimal Namespace 0 nodeset UA_ENABLE_STATUSCODE_DESCRIPTIONSĬompile the human-readable name of the StatusCodes into the binary. UA_ENABLE_TYPEDESCRIPTIONĪdd the type and member names to the UA_DataType structure. The advanced options need to be toggled toīe visible in the cmake GUIs. The advanced build option UA_FILE_NS0 can be used to override the XML REDUCED: Small namespace zero that passes the CTT.įULL: Full namespace zero generated from the official XML definitions. (Conformance Testing Tools of the OPC Foundation). But this namespace 0 is so small that it does not pass the CTT MINIMAL: A barebones namespace zero that is compatible with mostĬlients. May not be required for all applications. Namespace zero contains the standard-defined nodes.

Replacement is done with atomic operations so that the information model isĪlways consistent and can be accessed from an interrupt or parallel thread Nodes in the information model are not edited but copied and replaced. UA_ENABLE_NODEMANAGEMENTĮnable dynamic addition and removal of nodes at runtime UA_ENABLE_AMALGAMATIONĬompile a single-file release into the files open62541.c and open62541.h. Utility functions that are not essential to the SDK. UA_ENABLE_METHODCALLSĮnable the Method service set UA_ENABLE_PARSINGĮnable parsing human readable formats of builtin data types (Guid, NodeId, etc.). This is a new feature build upon events and currently marked as EXPERIMENTAL. UA_ENABLE_SUBSCRIPTIONS_ALARMS_CONDITIONS (EXPERIMENTAL)Įnable the use of A&C for subscriptions.
