Re: [Paparazzi-devel] FBW and AP...

[Alexis Lussier Desbiens]

Ahah... the problem was more stupid than that! My PPM_in was connected
to pin "RC RX" of the connector "FBW RC1"! It seems obvious to me that
this pin was used for PPM_in... but I was wrong! Running out of idea,
I just decided to try to connect it to other pins... and tried FOO2 of
the connector "FBW RC0"!

Ok now what the hell pin "RC RX" is supposed to be used for? And what
means FOO? What is the use of FOO1 and FOO3?

Again, I am using a Classix board...

Thanks!
