I got to the point in my first quad arducopter build where it came time to load the code, exciting!
With everything connected, (including ESCs) I proceeded to power up the board via USB.
The dim LED struck me as kind of odd, but at this point I don't know that what i've just done is a no. So I make 1 attempt to load the code whith no success obviously. That's when I unplugged it.
Upon closer inspection the manual I found it rather casually mentioned here:
"3. Upload the ArduCopter firmware to the APM.
- Plug the board into the USB. If you have ESCs connected to the board, you must also be powering the board via a battery (though the power distribution board if you're using the standard ArduCopter frame). If you do have the ESCs connected to the APM board and you don't power the independently of the USB cable, the code will not load and you may blow your outputs. (You can tell you're overloading your board if your APM LEDs are dim). "
I connected the battery, made a minor correction to my sketch folder name/location and the code loaded fine.
now when I power on the quad the motors beep really fast and nudge just a little....
I calibrated the esc's according to the manual and tested each motor idividually for proper spin direction
in kinderkram's build log, at the bottom (after you fry your outputs)
there is this warning
When you plug in the USB make sure you don't have your ESCs and motors connected.
Otherwise you will blow your outputs!
you guys know the next question.
Why is this warning not in the ArduCopter manual?
