How to read and write to MSFS Lvars

[roa]

Hi, I just wondered if someone could give a hint if it is possible to read and write to the MSFS's airplanes LVars that are using the G1000 or specific airplane type avionics ( B747, B787 A320)?

None of the G1000 and other specific avionics (B747,B787) knobs and buttons , but the "standard" HDG, ALT etc. are read or write able via SimConnect.

Read the "README.txt" that comes with FSUIPC7...
