Re: [Paparazzi-devel] New Cortex-M4 hardware platform

[Meier Lorenz]

I'm not sure if APM/ACM will want to wait forever for Arduino, that's all I can 
say so far.

The PX4 platform will be continuously developed, an there are some major 
research groups behind it. 

I would also recommend to compare the Atmel ARMs selected by Arduino to the F4 
(look at clock rates, RAM and floating point support). At least to my current 
knowledge the result will be pretty clear. 

Cheers,
Lorenz
