ESP-Modbus
|
||||
----------
|
||||
|
||||
Breaking Changes (Summary)
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The ESP-IDF component ``freemodbus`` has been removed from ESP-IDF and will be supported as a separate component. Additional information for the ``ESP-Modbus`` component can be found in the separate repository:
|
||||
|
||||
* `ESP-Modbus component on GitHub <https://www.github.com/espressif/esp-modbus>`__
|
||||
|
||||
The ``main`` component folder of the new application shall include the component manager manifest file ``idf_component.yml`` as in example below:
|
||||
|
||||
.. highlight:: none
|
||||
|
||||
::
|
||||
|
||||
dependencies:
|
||||
espressif/esp-modbus:
|
||||
version: "^1.0"
|
||||
|
||||
The ``esp-modbus`` component can be found in `component manager registry <https://components.espressif.com/component/espressif/esp-modbus>`__. Refer to `component manager documentation <https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html>`__ for more information on how to set up the component manager.
|
||||
|
||||
Applications targeting v4.x releases of ESP-IDF which use the new ``esp-modbus`` component should exclude the legacy ``freemodbus`` component from the build. This can be achieved using the below statement in project ``CMakeLists.txt``:
|
||||
|
||||
.. highlight:: none
|
||||
|
||||
::
|
||||
|
||||
set(EXCLUDE_COMPONENTS freemodbus)
