Hacking the APM (just a bit !!)

Hi all,

 

Following this thread (look at the picture) :

http://diydrones.com/forum/topics/open-pins-on-apmoilpan

 

I'd like to know what digital and analog pins can be used for other tasks than the original.

 

For example, if you don't need 8 INPUT and 8 OUTPUT channels, perhaps can you free this pins to other tasks ??

- For the ouptut I believe it's possible, no ? As analog input/output ?

- Perhaps for the INPUT channels it's not (because of the PPM encoder ?)

 

There stills 2 analog ports (AN6 and AN7) let free and easily accessible : thank you Jordi !

 

Is the pitot connection hackable too ? On what pin is it accessible ? Is it analog ?

 

Concerning the AN0 -> AN5, AN4 and AN5 are free, others are used for voltage dividers, which is great (I believe I will use just one). Is it possible to use the others as analog port (by shorting the divider resisances) ?

 

Does anybody know if it's possible to use all of this analog port as digital port (if needed) on the mega, and how ?

 

That's a lot of questions, so thansk for your answers !
