Read Sensor Temperature and Modbus Protocol

[photovoltaico]

Hello, I'm a newbie from Qt.

I wanto to envelop only a shell version-software that logging data from sensor box and other instruments. They comunicate whit :
- serial protocol
- modbus rtu protocol.
- I use embedded solution of Qt.

About that, Qt is under GPL license? WHere I can download it?
WHat is the best guide about it?

Also, about serial and modbus protocol where I can find an example that implement it?

About datalogging exist in Qt function that implement solutions for datalogging embedded system?

I think that Qt is the best solution for this problem!
