How can I add a parameter?

I'd like to add a parameter to arduplane that I can change during flight. How do I go about doing that?

I don't understand how the Parameters.h file works at all. I guess I don't have a full understanding of the C constructs used in it. Can someone explain to me how parameters are defined and initialized?

  • Ok, I figured it out by looking at the change logs for APM, but how much space is there for parameters? Last time I made a post complaining of a missing feature, I got the response that "parameter space is somewhat of a commodity." Is it going to run out of flash if I add a parameter? If so, how does it fail? Will it cause the ardupilot to crash or anything else dangerous like that?
