Add library on platformio (IDFGH-12435)

[mattia424]

Bye, Is there a simple way to load this library into the platformio environment? I have tried all ways but from the main.c I can't reach the header files

@mattia424 ,

The esp-modbus can be used with platforio environment. In order to accomplish this you need:

1. Download the latest library from v1.013.
2. Extract it to the path c:\Users\youruser\.platformio\packages\framework-espidf\components\ (Win path! should be adopted on linux) or to the 'your_proj_root\components' folder.
3. Create your project in platformio. In your root folder CMakeFiles.txt file add the lines as below:

   cmake_minimum_required(VERSION 3.16.0)
   set(EXCLUDE_COMPONENTS freemodbus) #to exclude the old freemodbus component which is part of platformio
   # Include parameters from common modbus folder (add the common parameters folder in the root of the project, if you need them
   set(MB_PARAMS_DIR "${CMAKE_CURRENT_SOURCE_DIR}/mb_example_common")
   list(APPEND EXTRA_COMPONENT_DIRS "${MB_PARAMS_DIR}")
   include($ENV{IDF_PATH}/tools/cmake/project.cmake)
   project(mbm)

4. In your pio_proj_root\src in the main.c you can include the
   modbus_params.h, mbcontroller.h and implement your modbus implementation using the stack API.
5. Compile the project in platformio CLI.

Perfect this solved my problem, I had missed the fact that it is a component and not just a library to be included
