@vermut rebase on master, apply your patches on top while reworking them, when you have something working please let me know so I can test it! Greatly appreciated!

Do want me to delete other folders as I did in my repo? Because I needed to do that so PlatformIO can use that repo as a source.

On that case you will need to create separate repos for SimpleModbusMaster and SimpleModbusSlaveSoftwareSerial

Dear people, Is this library compatible with Arduino FIO?

I have no idea. Chip seems to be the same, so I would say yes.

I have tested V10 with fio, but when we connected 4 or more devices, Modbus RTU started to give Comm fail.
