;
; to build and run directly on linux: pio run -e standalone -t exec
;
; to build and run on Windows, it needs winsock for the console input so:
;  - For the first time, install Msys2 (https://www.msys2.org/) and the GCC compiler with `run pacman -S mingw-w64-ucrt-x86_64-gcc`
;  - Then, build with `pio run -e standalone` to create the program.exe file
;  - run by calling the executable from the Mysys shell e.g. `C:/msys64/msys2_shell.cmd -defterm -here -no-start -ucrt64 -c <location>/.pio/build/native/program.exe`
;  - or use with Windows Terminal https://www.msys2.org/docs/terminals/

; Modbus
;  Creating the modbus registers is a multi-step process. Before it was in a shell script called generate_csv_and_headers.sh
;  but now moved to pio so everything is in python and cross-platform. The logic is as follows:
;  1. create a dummy modbus_entity_parameters.hpp file so the first pass compiles
;  2. compile the EMS-ESPcode with the EMSESP_MODBUS flag set
;  3. run the entity_dump test command and generate the dump_entities.csv file
;  4. use the dump_entities.csv file with update_modbus_registers.py script to generate the modbus_entity_parameters.hpp file
;  5. clean up everything and start again with the EMSESP_STANDALONE flag set
;  6. run the entity_dump test command again to create the real dump_entities.csv file
;  7. create the Modbus-Entity-Registers.md file
;  8. create the dump_telegrams.csv file
;
;  To run this in pio use the steps
;   pio run -e build_modbus -t clean -t build
;   pio run -e build_standalone -t clean -t build

# builds the modbus_entity_parameters.hpp header file
# pio run -e build_modbus -t clean -t build
