I am new to this forum, first of all try to speak English as best you can hahaha 
.
My problem is this, I want to know how to set the code that is compiled into Arduino (apm ArduPilot 3.2.1) and whether there is a guide or documentation to talk about the code, Iām following two guides this http://dev.ardupilot.com/wiki/building-ardupilot-with-arduino-windows/ and this youtu.be/SR0BpijXKxc
thank you very much for your time, and I welcome your comments
