v4.4.0

Add

• Add unit tests for all object type functions
• Add CMake presets for simplified usage of CMake in CI/CD

Changed

• Separate all object type functions into separate files
• Adjust repository structure to recommendations in "Professional CMake - A Practical Guide"
• Move website to separate repository

Attention: This release introduces a breaking change:

Handle basic type implementations with separate type function files and in consequence enlarge the object entry flags from CO_OBJ_DNPRW to CO_OBJ_DNAPRW. This change requires adjustments in existing object dictionary definitions:

old:
  {CO_KEY(0x1001, 0, CO_UNSIGNED8 |CO_OBJ____R_), 0, (CO_DATA)(&Obj1001_00_08)},

new:
  {CO_KEY(0x1001, 0, CO_OBJ_____R_), CO_TUNSIGNED8, (CO_DATA)(&Obj1001_00_08)},
    add an underscore or A ---^         ^
    ensure type starts with CO_T -------'

v4.3.1

Fixed

• Rollback of 32bit direct storage in 16bit machines (is not compiling reliable)

Changed

• Add a warning for 16bit microcontroller using direct storage in the object dictionary in docs

v4.3.0

Added

• Add a note in documentation to usage and api about the need of sorted object dictionary
• Add support for SDO client segmented transfers @tonbo777
• Add support of mapping values with 3 bytes in PDOs
• Introducte callbacks for read/write PDO mapped values larger than 4 bytes

Changed

• Adjust SDO client API documentation to reflect conditions for expedited and segmented transfers

Fixed

• Avoid variable declaration if SDO client is disabled @jernejsk
• Allow direct data in object dictionaries running on 16bit microcontrollers

Note: The datatype in the object dictionary was uintptr_t in previous versions. For 16bit microcontrollers uintptr_t may contain only 24bit instead of the required 32bits for direct data storage. For this reason, in version 4.3.0 and later the object dictionary should use CO_DATA as data type.

v4.2.0

Added

• Add callback CONmtResetRequest() for handling specific application and/or communication reset features
• Add feature: SYNC producer @dozack
• Add feature: SDO client (limited to expedited transfers) @dozack

Changed

• Change static website generator to Material for MkDocs

Fixed

• Fix navigation link in sidebar to quickstart example
• Correct restarting of block transfer after aborting a running transfer by a client restart
• Correct abort message when writing to 1014h:00h while active or with value out of range
• Correct abort message when writing to 1003h:00h with value out of range
• Fix data copy loops in NVM simulation read and write functions

v4.1.8

Added

• Add the option to exclude LSS and/or parameters Domen2242/configurable_features
• Detailed description of API function COObjTypeUserSDOAbort()
• Example article explaining the usage with RTOS and baremetal
• Example article explaining the firmware upload with user domains

Fixed

• Interface description and examples of API functions on Page "Object Entry"
• SDO segmented download of basic data type
• SDO block upload and download of basic data type
• correct some Domain and String object definitions in documentation

v4.1.7

Added

• Introduce COObjTypeUserSDOAbort() to define manufacturer-specific SDO Abort codes within type functions
• Add CMake toolchain files for ARM-GCC Cortex-M3, M4 and M7

v4.1.6

Added

• Explain the possible PDO transmission options
• Add example which describes how to setup and use a dynamic object dictionary
• Add type functions for EMCY COB-ID (1014) and SYNC COB-ID (1005)

Changed

• Clarify the arguments in type functions read() and write()

Fixed

• PDO Timer Config when entering the OPERATE state multiple times
• Fix the random bogus frame passed to function when no CAN frame is received
• Fix issues in SDO block upload and download protocol

v4.1.5

Added

• Allow disabling the EMCY module by setting NULL for emcy code table.

Fixed

• Explain how to setup EMCY in quickstart example (even if not used in this application).
• Fix NMT reset when EMCY is not used (no EMCY code table).
• Fix broken RPDO communication setup @cjardin112.

v4.1.4

Added

• Allow CAN driver polling for testing and demo purpose (Don't use this in production!).
• Implement a simple NVM driver simulation in RAM.

Fixed

• Add CO_TASYNC in quickstart object entry to trigger PDO transmission on write access.

v4.1.3

Added

• Standard changelog file in the project root.

Fixed

• CO_OBJ_TYPE const qualifier @cesarvandevelde.
• COBID macros: use 11-bit mask for std IDs @cesarvandevelde.
