* This file define the default configuration of the copter
* It contains two types of parameters:
* - The global parameters are globally defined and independent of any
* compilation profile. An example of such define could be some pinout.
* - The profiled defines, they are parameter that can be specific to each
* dev build. The vanilla build is intended to be a "customer" build without
* fancy spinning debugging stuff. The developers build are anything the
* developer could need to debug and run his code/crazy stuff.
*
* The golden rule for the profile is NEVER BREAK ANOTHER PROFILE. When adding a
* new parameter, one shall take care to modified everything necessary to
* preserve the behavior of the other profiles.
*
* For the flag. T_ means task. H_ means HAL module. U_ would means utils.
