Latest

The biggest and the most important release so far. Majority of the source code has been rewritten from scratch. The library is header-only now, which makes it much easier to compile on different exotic platforms. Although features included in this release break backwards compatibility with v2.0 and require changes to be made in user code, upgrading to v3.0 is highly recommended due to the number of improvements.

Changes:

The library is header-only now. The old build system based on CMake is no longer necessary.
Very significantly reduced binary size (~16kB (v2.0), -> ~7.3kB (v3.0))
Significantly improved code structure, maintainability and performance
Alignment safety no longer relies on compiler attributes (__attribute__((packed)) is 'broken' on XC16 compilers)
Replaced inttypes.h with stdint.h
All register operations are now done through register callback functions.
All data is received with a data callback on master side now.
Added support for Modbus TCP
Added setters/getters for ModbusMaster and ModbusSlave structure members
Added support for custom allocators. This mechanism can be used to replace old LIGHTMODBUS_STATICMEM*
Added a new CMake config which allows liblightmodbus to be used a CMake package
Added a (very) experimental C++ API
Added a ModbusBuffer type for holding and managing allocated frames
Added some debug utilities
Created a separate repository for ESP-IDF component files
Integrated with GitHub actions
Removed the examine addon
Improved error handling
Types are now consistently named with PascalCase
Renamed many functions and type names
Dropped support for Launchpad
Prettier docs, thanks to https://github.com/jothepro/doxygen-awesome-css

Pre-release

THIS IS A RELEASE CANDIDATE 2

The biggest and the most important release so far. Majority of the source code has been rewritten from scratch. The library is header-only now, which makes it much easier to compile on different exotic platforms. Although features included in this release break backwards compatibility with v2.0 and hence require changes to be made in user code, upgrading to v3.0 is highly recommended due to the number of improvements.

Changes:

The library is header-only now. The old build system based on CMake is no longer necessary.
Very significantly reduced binary size (on AVR full v2.0: ~1600b, full v3.0: ~7300b)
Significantly improved code structure, maintainability and performance
Alignment safety no longer relies on compiler attributes (__attribute__((packed)) is 'broken' on XC16 compilers)
Replaced inttypes.h with stdint.h
All register operations are now done through register callback functions.

v0.8-beta

b135e29

Beta 0.8 Pre-release

Pre-release

This is probably pre-final release! 😄

This release includes:

Holding registers support
Coils support
Discrete inputs support
Input registers support
Minor optimizations and improvements

So, well this is basically what full version is planned to include.

Before v1.0 few things have to be improved:

Makefile
Wiki
Code may be optimized in some places
Library needs a little bit more of real testing
Check for memory leaks and bugs
Probably *.deb packages will be introduced (Well, they are here, but I do not guarantee them to work properly)
