I installed arduino on a new computer and once again got this error:
avrdude: stk500_getsync(): not in sync: resp=0×00
avrdude: stk500_disable(): protocol error, expect=0×14, resp=0×51
If you have the old style (1.0) of ardupilot, make sure you are using the board settings for Arduino Diecimilia (Atmega168)
USB love
I am amazed at all of the products sparkfun seems to just roll out, things you never knew you’d need… but soon become quite attached to! A prime example is their FTDI braekout, allowing you to connect over USB to the ArduPilot board.
I am pretty amazed by whoever figured out what hardware to put together, and how to write a driver for it. That being said… I am somewhat frustrated by the fact that it is kind of hit-or-miss for Windows to realize if it is a COM port or not! It seems that every 3rd attempt or so at using it, my computer will recognize that the USB device is plugged in, but not that it’s an active COM port. The only solution so far seems to be to uninstall the drivers and reinstall them. If that’s what it takes… then until I figure out exactly what the bug is, then that’s my suggestion for people with this problem too!
It turns out that the sim is not as strait forward as I expected, and if anyone else is having trouble with it, then feel free to chime in. One of the most annoying things to hear as a programmer is when someone uses something you developed and says “It didn’t work. why?” without giving any details as to how they are using it, what specifications are they running, what kind of errors are being generated, or anything that might be useful in diagnosing the problem! So with that being said, here is the basic setup I’m using:
-Windows XP on a Dell Latitude D820 laptop
-2nd generation ArduPilot board, with the solder jump made to power from an external battery
-external 4.8 volt battery source from 4x AA batteries
-USB connected FTDI breakout board for uploading data to the board
Is that what most of you guys are doing? Or are you using power from the plane across the extra servo-in port? Is anyone using a normal serial cable based breakout board instead of the FTDI’s USB one?
