Hi, Although I can hold my own flying a drone using Taranis Radio, I must admit, I’m less than proficient at python programming. Although Caleb does an excellent job describing the code and presenting it in a way, this old dog can follow. It seems, I’m stuck.
I’m using the lauchSitl code as provided in the Drone Primer Videos, but it seems to either be missing a main () subroutine or perhaps I have fat fingered something wrong, either way, it will not execute and produce the error mentioned above.
See output
