Hi We are looking to develop a simple communication Module. We want to Use LORA RA02 which should be communicating in 1 : N using a PIC micro controller. In the sense the Lora RA02 should be addressable and each Lora should be able to communicate with each other. Preffered Microcontroller would be PIC24FJ256GA702 or PIC 18F4520 . We would be requiring the programme and Circuit Layout.

I am an italian engineer and working on a bachelor project to be handed over beginning of September, so I am in kind of a hurry since I'd have to write a report too. It is about control of a microgrid via voltage source converter with integration of storage, wind and solar power in the grid using Matlab/Simulink. I already modelled some parts (but had problems to make them work) and have some...
