Re: [Paparazzi-devel] Source code analysis of paparazzi

[Felix Ruess]

Hi Matthieu,

If you want only two examples, I would suggest the following aircrafts from the example conf:

- rotorcraft, stm32f1: Quad_LisaM_2

- fixedwing, lpc21: Microjet

Of course these only represent a small subset of Paprazzi...

Cheers, Felix

Hi Michal,

Thanks. Actually, a single-threaded mainloop is simpler to analyze, so
I'll stick with that for the moment.

However, I would still be interested if you could give me the name of 2
configurations that are different in both dimensions {fixedwing,
rotorcraft} and {lpc2148,stm32}.

Thanks,
Matthieu
